通过调查研究，对中学生的学习心理有了初步的了解，为准确地把握当前中学生的学习心理动向，深化教学改革，加强教育教学的针对性，
提高教育教学的实效性，探索实施素质教育的新路子，提供了客观依据。
二、调查的具体目标和方法
(一)具体目标
1、中学生的学习心理现状
2、当前中学生的学习心理特点
3、当前中学生的学习心理成因及对策
(二)调查方法
学生问卷，内容涵盖教育价值观、学习态度、学习需求和学习目的四个方面。
问卷调查在六中学进行，共发问卷80份，回收有效问卷70份，接近理想的高效样本数。
三、调查结果
对学生问卷调查分析，中学生的学习心理具有明显的时代特征。

1、教育价值观
调查显示，大部分中学生具有较为明确的教育价值观。
74%的学生认为学习的作用是提高自身素质，10%的学生认为学习的作用是为了考大学，16%的中学生没有考虑。
调查还显示，中学生的教育价值观带有显著的经济社会特征。
他们认为，青年人的经济收入与受教育程度成正比，其中65%的学生认为大学生挣钱多，25%的学生认为高中毕业生挣钱多，8%的学生认为初中毕业生挣钱多。
2、学习
态度
调查结果表明，67%的学生对学习的热情较高，24%的学生对学习的热情中等，9%的学生害怕学习。
这与他们“考大学”意识淡化是相一致的。
值得注意的是，害怕学习的学生数占相当份额。

1、教育价值趋向多元化、务实化、功利化
他们中的大部分人已经认识到了教育的重要价值在于帮助他们提高自己的综合素质，使他们掌握生存、生活所需的基本的文化科学知识，以增强自己在未来社会的竞争能力。
在此基础上，部分家庭经济条件较好且成绩优秀的学生则致力于追求更高等的教育。
中学生的教育价值观的另外两个特点是务实化和功利化。
中学学生越来越强烈地追求未来教育输出的经济价值，他们中的很多人从经济的角度去衡量所学课程的价值，继而决定自己在不同课程上的努力程度。
他们要求课程教学更多地联系生活和生产实践，渗透更多的实用技术。

第五篇：污水处理厂调查报告及英文
宣化区污水处理厂的调查报告 调查时间：2015-2-21
调查地点：河北省张家口市宣化区污水处理厂
科学处理污水是经济社会发展的迫切要求，也是城镇建设过程中必须面对的现实问题。近年来，县委、县政府高度重视城镇环境卫生整治工作，将这项工作作为改善城镇人居环境，推进城乡统筹发展、构建和谐社会的重要抓手。过去的几年，宣化区在污水处理方面做了大量的工作，取得了一些成效。
宣化区污水处理厂及污水管网工程在2001年经省发展计划委员会立项批复。该项目是国家支持的环境资源保护项目。2004年经国家发展和改革委员会办公厅批复建设，计划总投资6316万元。该工程是处理我们的生活、城镇建设的污水的重要环节，近期日处理污水3万m³，远期日处理污水5万m³。
厂址位于宣化区城区东南5公里处，占地65.2亩；同时建设配套
一、二级污水管网25.8公里,主要是东沙河及南环线截流干管以及部分旧城区管网。污水厂自运行以来，运行稳定，现阶段日进水量1.6万吨，COD、NH3-N等各项污染物指标均达到排放标准。
一、污水处理工业流程 （1）粗格栅间
粗格栅设在进水泵房之前，以去除进厂污水中颗粒较大的杂质，使进水泵安全稳定运行。其设计流量为3325m3/h，此构筑物内的主要设备有回转式格栅。（2）进水泵房
污水从粗格栅间出来就流进进水泵房，泵房结构简单紧凑，选用污水离心潜水泵，据工作人员说该泵具有不堵塞型流道、效率高能耗低的优点，有效处理污水同时还节约了资源，其设计流量为3325m3/h。将初步处理后的污水抽入细格栅间。（3）细格栅间
在细格栅间内安装有机械细格栅、螺旋输送压实机等设备，用来处理小颗粒垃圾，将其过滤出来的垃圾装车匀速到指定位置填埋；其中还在里面同时进行细菌的反硝化，产生泡沫状的相互硝化的产物，之后用鼓风机吹起沉淀的颗粒，防止堆积沙子，从而把土和沙子处理掉。其设计流量为3325m3/h。（4）旋流沉砂池
旋流沉砂池主要设备是砂水分离器，其优点为占地面积小，沉砂效果好，安装使用方便等。设计流量3325 m3/h沉砂池直径4.2m，水深4m。（5）计量设备
沉砂池后有许多仪表，在沉砂池后设置电磁流量计，可以对进厂污水流量进行连续监测，同时设置水质监测仪表，如PH计、温度计、SS计，把测量信号传至中央控制室，防止任何纰漏的出现。（6）厌氧选择池
露天厌氧选择池内有缓慢移动的潜水搅拌器，回流污泥与污水在池中接触、混合反应，可以达到部分除磷作用，并改善活性污泥的性质，还能分离喜氧细菌和厌氧细菌。设计流量1250m3/h，池有效容积3925 m3/h。（7）奥贝尔氧化沟 奥贝尔氧化沟，它为椭圆形钢筋混凝土池，分为2座。每池分为三条环形沟道，污水依次进入外沟道、中沟道及内沟道，最后经中心岛的出水并排入沉淀池配水井。设计流量1250m3/h，每座有效容积11000m3，混合液浓度4.5 g/l，设计水深4.2m，水力停留时间17.6h。
并且奥贝尔氧化沟是整个处理系统的核心部分，其主要功能是使培养、驯化后的活性污泥降解、吸附、凝聚有机物，并通过细菌的作用使悬浮颗粒和溶解颗粒易于沉淀，使出水中的有机物含量降低。
每座氧化沟安装有转碟曝气盘10套，外沟道的溶解氧控制在0.5mg/l，在此同时进行氧化、硝化及反硝化。中间沟道及外沟道溶解氧分别控制在1mg/l和2mg/l，对污水中的有机物进一步氧化，保证出水中的有机物含量达到设计要求。（8）沉淀池
氧化沟处理后的水会排入沉淀池，沉淀池采用辐流式沉淀池，中心进水，周边出水，直径D＝38m，共2座。设集配水井二座，经过沉淀后的污水进入接触池。每座沉淀池设周边驱动的全桥式刮吸泥机，沉淀池泥至回流及剩余污泥泵站。设计流量1813m3/h，最大表面负荷0.8 m3/ m2.h，单池池边水深4m，停留时间4.3h.（9）接触池
由于要保证出水的清洁程度达标所以需进行消毒处理，因此设接触池1座：1813 m3/h流量，接触时间30min,有效接触容积1056 m3，有效水深4m。本工程采用二氧化氯消毒方式，负责污水二级出水的接触池加氯。污水的加氯投加点在接触池前端。设计回流1813 m3/h，平均加氯量8 mg/l，单台有效产氯量7.5kg/h。（10）回流及剩余污泥泵房
由于部分水会沉淀出一些污泥，所以回流污泥泵采用潜水轴流泵，剩余污泥的提升采用潜水离心泵，土建结构简单紧凑。回流污泥量1250 m3/h，污泥含水率99.1%。（11）加氯间
本工程采用二氧化氯消毒方式，负责污水二级出水的接触池加氯。污水的加氯投加点在接触池前端。设计回流1813 m3/h，平均加氯量8 mg/l，单台有效产氯量7.5kg/h。
二、污水处理的意义
随着的发展,城市水资源短缺的压力越来越大,追究城市水危机的根本原因,人们越来越认识到,是水的社会循环超出了水的自然循环可承载的范围.因此,只有充分尊重水的自然运动规律,合理地使用水资源,使上游地区的用水循环不影响下游水域的水体功能、社会循环不损害自然循环的客观规律,从而维系或恢复城市乃至流域的良好水环境,才是水资源可持续利用的有效途径.这就要求我们从“取水－输水－用户－排放”的单向开放型的用水模式转变为“节制地取水－输水－用户－再生水”的反馈式循环流程,提高水的利用效率.实现这一重大用水模式的转变,加强污水再生利用是关键.随着科学技术的进步,城市污水已不再是废水,而是一种宝贵的资源.既然是一种资源,就要最大程度的利用.提高城市污水的再生利用率,一是可以减少污染物排放,二是节约了有限的水资源.水利部水资源司副司长程晓冰在由清华大学和中国水网主办的“2010城市水业战略论坛”上发表讲话,他指出,我国水资源短缺,城市缺水问题突出,污水处理回用是战略选择,意义重大.城市污水处理回用在替代清洁水源的同时减少了污水排放量,降低了城市排污负荷,具有水量稳定、输水距离短、制水成本低等特点,可以提供安全可靠的替代水源,是解决城市缺水问题的战略选择.推进污水处理回用工作充分体现了科学发展观以人为本的要求,反映了广大人民群众的迫切愿望,是推进城市化建设的客观需要,是实现水资源合理配置、科学保护、循环利用的重要手段,对建设资源节约型、环境友好型社会意义重大,对我国经济又好又快发展意义重大.三、存在问题
（一）环境卫生基础设施建设比较薄弱。城市管网向农村延伸刚刚起步，宣化区下水道管网尚未形成。
（二）本地城镇污水处理系统还处于发展阶段。
（三）人们环保意识差，不懂得资源保护与可持续性发展的关系，缺乏遏制环境污染的主观能动性，对环境“脏、乱、差”现象习以为常，熟视无睹。所以仍有自然排放的现象存在。
四、存在问题的原因
经过我的研究与对工作人员的询问我们认为造成城镇污水无害化处理难的原因是多方面的，主要有：
（一）重发展，轻环境。先发展后治理观念一些企业中仍是主导观念，在搞经济建设、抓工业发展的过程中，污水处理问题相对滞后。
（二）宣传不到位。政府和社会的宣传力度还不到位，人们意识不到污水处理的难度，水资源浪费严重。
（三）监管力度有纰漏。有关部门的监察还有疏漏，造成有人趁机钻空子，造成水污染。
（四）城镇污水处理设施的建设资金缺口较大。城镇污水处理设施建设属于公益性项目，但公共财政资金投入却十分有限，导致污水处理厂设备落后，处理效率低。
（五）相应的处罚法律法规不够完善。处罚力度不够严导致很多企业无视法律法规，处罚过后依然我行我素，污染环境问题不能完全解决。
（六）缺乏相应的检举方法和奖励措施，公民参与企业污染举报积极性不高。
五、提出建议
针对上述问题我们提出一些建议：
1.强制要求企业设立环境监测部门，对本企业对环境污染进行检测和评估。 2.加大政府资金投入，进一步完善符合国家标准的生活污水处理场所。
3.学习国外先进污水处理技术，引进国外先进污水处理设备，提高污水无害化处理效率。
4.搭建垃圾污水处理设施，建设多元融资平台以解决污水处理厂资金问题。
5.建立完善环境卫生保洁的法律法规和惩处措施，做到政府管理有法可依，企业生产心有所畏。
6.社会和政府加强对公民节水和环保的教育宣传，节水从每一位社会公民做起以达到最好的节水效果。
7.政府设立相应的举报部门和奖赏措施，提高公民参与社会监督的积极性。 8.试行对城市居民生活下水排放收费措施，以此增强居民节水意识。
六、污水处理调查感想 通过这次调查，我学到了很多关于自己专业的知识，而且好多都是课堂上学不到的。我对自己的专业有了新的认识和理解。对自己将来的工作方向有了初步的了解。在这次调查中我遇到很多困难，但是我都努力克服了。在整个过程中我学会了怎么与人交流和沟通，也学会了怎么独立解决问题。
在这次调查中，我了解到污水处理是能源密集型的综合技术。一段时期以来,能耗大、运行费用高一定程度上阻碍了我国城市污水处理厂的建设,建成的一些处理厂也因能耗原因处于停产和半停产状态。在今后相当长的一段时期内,能耗问题将成为城市污水处理的瓶颈。能否解决耗污水厂的能耗问题，合理进行能源分配，已经成为决定污水处理厂运行效益好坏的关键因素。能耗是否较低，也是未来新的污水处理厂可行性分析的决定性因素，开发能效较高的污水处理技术，合理设计及运行污水处理厂，必将是未来污水处理厂设计和运行的必由之路。为此，实施污水处理厂的创新管理模式不失为一条切实可行的道路。水是不可缺少的一部分，是人类生存的必要条件。我国是水资源短缺的国家，地区缺水问题尤为突出。随着经济发展和城镇化进程的加快，水污染问题也越来越严重。切实加强和改进城镇供水、节水和水污染防治工作，促进经济社会的可持续发展，维持生态平衡，已成为社会发展的一项重要举措，也是每个公民应尽的义务，作为一名大学学生，我们更应该从我们自身做起，从点滴做起。
Survey Xuanhua District sewage treatment plant Survey Time: 2015-2-21 Survey Location: Zhangjiakou, Hebei Xuanhua District Wastewater Treatment Plant Science sewage treatment is an urgent requirement of economic and social development, but also practical problems of urban construction proce must face.In recent years, the county government attaches great importance to urban environmental remediation work, will this work for the improvement of urban living environment, promoting urban and rural development, an important starting point to build a harmonious society.Over the past few years, Xuanhua District sewage treatment has done a lot of work and achieved some succe.Xuanhua District sewage treatment plant and sewer network project in 2001 by the Provincial Development Planning commiion approved the project.The project is environmental conservation projects supported by the state.2004 by the Office of the National Development and Reform commiion approved the construction, plans a total investment of 63.16 million yuan.The project is to deal with our lives, an important part of the sewage of towns, the recent sewage treatment 30000 m³, long-term daily treatment 50000 m³.Site is located 5 km southeast of the city of Xuanhua District, covering 65.2 acres;at the same time supporting the construction of one or two 25.8 km sewage pipe network, mainly East River and KSL intercepting pipes and part of the old city pipe network.Since the wastewater treatment plant self-running, stable operation, 16,000 tons of water into the stage day, the pollutant index COD, NH3-N and so have to meet emiion standards.A sewage treatment industrial procees(1)between the coarse grid Coarse grid in the water before pumping stations, sewage into the plant to remove larger particles of impurities, safe and stable operation of the pump intake.The design flow is 3325m3 / h, the main equipment within this structure there are rotary grill.(2)water pumping station Advantages of sewage from between the coarse grid to flow out into the water pumping stations, pumping stations simple and compact structure, the selection of sewage submersible centrifugal pumps, according to the staff

dosing point sewage pond in the front contact.Design reflux 1813 m3 / h, the average amount of chlorine 8 mg / l, a single effective yield chlorine 7.5kg / h.Second, the significance of the sewage treatment With the development of urban water shortages increasing preure to pursue the root causes of urban water crisis, it is increasingly recognized that community water cycle beyond the natural cycle of water can carry a range.Therefore, only full respect for the natural movement of water, the rational use of water resources, making water recycling upstream region does not affect the function of water downstream waters, without prejudice to the objective laws of social cycle natural circulation, thereby maintaining or restoring good water environment and the watershed of the city, The effective way is the sustainable use of water resources which requires us from "water-user" into open water unidirectional mode is "sparingly wateruser-recycled water" feedback circulation procees, improve water use efficiency.achieve this major shift patterns of water use and enhance wastewater reuse is the key.With the advancement of science and technology, urban sewage is no longer a waste, but a valuable resource.Since is a resource, it is neceary to maximize the utilization.improve urban sewage recycling rate, one can reduce pollutant emiions, and second, to save the limited water resources.Water Division of Water Resources Deputy Director Xiao-ice from Tsinghua Speaking on the university and China Water Network's "2010 Urban Water Sector Strategy Forum", he pointed out that the shortage of water resources in China, urban water shortages highlight, wastewater treatment and reuse is a strategic choice, significant urban wastewater treatment and reuse in Alternative sources of clean water while reducing emiions, reducing the city sewage load, with water stability, water a short distance, low cost of water can provide a safe and reliable alternative water sources, is a strategic choice to solve the city's water shortage Propulsion wastewater treatment and reuse work fully reflects the scientific concept of development is about people's demands, reflecting the urgent desire of the maes, is to promote the urbanization objective need, is an important means to achieve rational allocation of water, scientific conservation, recycling for building a resource-saving and environment-friendly society of great significance to China's fast economic growth is significant.Third, there is a problem(A)environmental health infrastructure is weak.Distribution network extends to rural areas has just started, Xuanhua District sewer pipe network has not yet formed.(B)the local municipal wastewater treatment system is still in the development stage.(C)poor awarene of environmental protection, do not know the relationship between conservation and sustainable development of resources, lack of initiative to curb environmental pollution to the environment "dirty, chaotic, and poor" phenomenon for granted, turn a blind eye.Therefore, the existence of the phenomenon are still natural emiions.Fourth, the problem of reason After my research and ask our staff to blame for urban sewage treatment and disposal difficult for many reasons, including:(A)re-development, light environment.After the first few companies in the development of the concept of governance is still the dominant idea in economic construction, caught in the proce of industrial development, sewage treatment is lagging behind.(B)the publicity is not in place.Propaganda of the government and the society is not in place, people are not aware of the difficulty of sewage treatment, water waste.(C)supervision flawed.There are omiions surveillance departments, resulting in people taking advantage of a loophole, causing water pollution.Construction funds(four)of urban sewage treatment facilities gap larger.Urban sewage treatment facilities are public projects, public financial investment is very limited, leading to the sewage treatment plant equipment behind, low proceing efficiency.(E)the appropriate punishment laws is inadequate.Strict punishment is not enough cause many companies ignore the law and regulations, after the punishment is still its own way, can not completely solve the problem of environmental pollution.(Vi)lack of appropriate methods and incentives to report, citizen participation enterprise reporting pollution are not enthusiastic.Fifth, make recommendations To solve these problems we propose some suggestions: 1.force businees to set up environmental monitoring department of the enterprise for the detection and aement of environmental pollution.2.increase government funding to further improve the sewage disposal sites in line with national standards.3.Learn the advanced wastewater treatment technology, the introduction of foreign advanced sewage treatment equipment to improve the efficiency of wastewater treatment and disposal.4.to build waste water treatment facilities, the construction of multi-financing platform to solve the financial problems of sewage treatment plants.5.Establish and improve environmental sanitation in the laws, regulations and punishment measures, so that government law, the production heart and fear.6.Government to strengthen the social and civic education and promotion of water-saving and environmentally friendly, water-saving society from every citizen to start saving in order to achieve the best results.7.The government set up the appropriate reporting department and reward measures to increase citizen participation in social monitoring initiative.8.Trial of urban residents living water emiions charges measures in order to enhance awarene of water conservation residents.Six sewage treatment survey feelings Through this investigation, I learned a lot about their own profeional knowledge, but many are le than the claroom.I myself have a new profeional knowledge and understanding.The future direction of their work have a preliminary understanding.In this survey, I encountered many difficulties, but I try to overcome.Throughout the proce, I learned how to communicate with people and communication, but also learned how to solve problems independently.In this investigation, I learned that sewage treatment is a comprehensive technical energy intensive.Over the years, energy consumption, operating costs hindered the construction of urban sewage treatment plants to some extent high, built of some treatment plants is also due to the reason in the cut consumption and semi-shutdown state.In the future for a long period of time, energy iues will become the bottleneck of urban sewage treatment.Can solve the energy consumption of the wastewater treatment plant problems, make reasonable energy distribution, sewage treatment plant has been decided to run benefit the quality of the key factors.Energy consumption is low, the decisive factor is the future of a new sewage treatment plant feasibility analysis, develop a high energy efficiency of sewage treatment technology, reasonable design and operation of sewage treatment plants, sewage treatment plants is bound to be the future design and operation of the only way.To this end, the implementation of the sewage treatment plant management model innovation may well be a feasible way.Water is an indispensable part, is a neceary condition for human survival.Ours is a shortage of water resources at national, regional water shortage is particularly prominent.With the rapid economic development and urbanization, and water pollution problems are more serious.Strengthen and improve urban water supply, water conservation and water pollution control work to promote sustainable economic and social development, to maintain ecological balance, has become an important measure of social development, but also the obligation of every citizen, as a university students, we should start from ourselves, from scratch.
