Poverty高碑店污水处理厂实习报告本次实习主要是通过工作人员的悉心介绍与讲解，能够使我们更好得了解专业知识，对污水处理现状有个基本的了解；同时也能在了解基本工艺流程的基础上，结合所学的知识，充分认识到当今水资源问题的重要性，为解决或改善水资源问题打下一定的基础。1 简介1.1 地理环境及气候北京市属温带半干旱半湿润干燥季风气候区。多年平均降雨量 595 毫米，年降水
12、总量99. 96 108m3可形成地表径流 21.98108m3，地下水资源为 27. 09108m3。降水量在时间和年度上是极不均衡的。同时，北京市的水资源人均不到 300 立方米，仅占全国平均水平的八分之一，属于缺水城市。按联合国规定的人均水资源丰水线标准(3000m 3/人) 和警戒线标准( 1700m 3 / 人)，北京市水资源量的承载能力为: 最佳人口规模 92 万人，最大人口规模 162. 4 万人。而 2008 年北京市人口总量已达 1633 万人，为水资源最大承载人口的 10. 06 倍，已经大大超过了北京市水资源的承载力。在水资源紧缺的前提下，北京仍然面临着水污染严重的问题。
13、北京 1 年大概需要 30 亿40 亿吨的水，城区每年排放 9 亿吨污水，现在每年北京各种品质的再生水利用已达到 6亿吨，仅北京排水集团每年即可生产各种品质的再生水七八亿吨，也就是说可以解决北京1/5-1/4 的水源。1.2 高碑店污水处理厂简介北京市高碑店污水处理厂由北京市市政工程局负责建设，北京市市政工程设计研究总院设计，北京市第四市政工程公司施工。该处理厂是北京市城市总体规划拟建的 16 座城市污水厂中规模最大、也是目前全国最大的污水处理厂，承担着市中心区及东部工业区总计9661 公顷流域范围内的污水收集与治理任务，服务人口 240 万，占地 1020 亩，远期建设规模 250 万 m3
14、/d，近期建设规模 100 万 m3/d，占全市污水处理总量的 40%。19841990 年设计，1990 年开工，1993 年底建成通水，经过运行考核，出水水质及处理量均达到设计要求。据观测，通惠河下游的水质已开始还清，河水中的溶解氧已升至these precious and worth cherishing.

25、改污水为二级处理出水灌溉，使该地区的农作物及土质，地下水水质污染得以改善，产生了很好社会效益和环境效益。在高碑店污水厂一期工程建设的同时，通惠河南岸污水截流工程亦同时建设，以完善该流域污水管网系统。工程于 1999 年 8 月完成，流域内 100 万 m3/d 污水将全部汇至高碑店污水处理厂。作为一期工程的续建项目，经国家计委及市计委批准，1996 年二期工程正式开工，工程总投资为 11.2 亿元人民币，其中包括瑞典政府贷款 1.73 亿瑞典克郎。工程于 1999 年 9 月竣工通水。高碑店污水厂的建成投产，将彻底解决北京市中心区及东郊地区的水环境污染，还清通惠河，是北京市“九五”计划和 20
26、10 年远景规划的重要组成部分，将为把北京市建成环境优美、基础设施齐全的国际化大都市作出积极的贡献。同时 100 万 m3/d 的出水还可为工农业生产提供第二水源，对于缓解北京市的水资源紧张状况，起到积极的作用。2 高碑店污水处理厂工艺简介与工艺参数介绍高碑店污水处理部分采用的是传统活性污泥法工艺；污泥处理部分采用的是两级中温厌氧消化的处理工艺，消化后的污泥，经带式压滤机脱水外运。污泥消化产生的沼气，主要用于发电，来驱动鼓风机和进水泵。沼气发动机的热水，作为消化污泥加热的热源，实现热电联供和资源的综合利用。传统活性污泥法为二级处理工艺：一级处理包括格栅、泵房、曝气沉砂池和矩形平流式沉淀池；二级
27、处理采用空气曝气活性污泥法。污泥处理采用中温两级消化技术，消化后经脱水的泥饼外运作为农业和绿化的肥源。消化过程中产生的沼气用于发电可解决厂内部分用电。2.1 高碑店污水处理厂污水进出厂标准根据我国城镇污水排放标准 GB18918-2002以及城镇污水处理厂污染物排放标准（GB18918-2002） ，城镇污水处理厂主要处理的城镇污水，指城镇居民生活污水，机关、学校、医院、商业服务机构及各种公共设施排水，以及允许排入城镇污水收集系统的工业废水和初期雨水等。根据城镇污水处理厂排入地表水域环境功能和保护目标，以及污水处理厂的处理工艺，将基本控制项目的常规污染物标准值分为一级标准、二级标准、三级标准。
