第一章设计说明书1.1城市污水处理概论城市污水处理是指为改变污水性质，使其对环境水域不产生危害而采取的措施。
城市污水处理一般分为三级：一级处理，系应用物理处理法去除污水中不溶解的污染物和寄生虫卵；二级处理，系应用生物处理法将污水中各种复杂的有机物氧化降解为简单的物质；三级处理，系应用化学沉淀法、生物化学法、物理化学法等，去除污水中的磷、氮、难降解的有机物、无机盐等。
至于采取哪级处理比较合理，应视对最终排出物的处理要求而定。
城市污水处理技术就是利用各种设施设备和工艺技术，将污水所含的污染物质从水中分离去除，使有害的物质转化为无害的物质、有用的物质，水则得到净化，并使资源得到充分利用。
城市污水处理技术通常有物理处理技术、化学处理技术、物理化学处理技术、生物处理技术等。
典型的物理处理技术在城市污水处理中应用的有沉淀技术、过滤技术、气浮技术等。
典型的化学处理技术和物理化学处理技术有中和、加药混凝、离子交换等。
典型的生物处理技术有好氧牲氧化分解和厌氧生物发酵技术。
城市污水处理工艺，实际上是以上这些技术的应用与组合。
城市污水处理工艺：城市污水处理工艺按流程和处理程序划分，可分为预处理工艺，一级处理工艺、二级处理工艺、深度处理工艺和污泥处理工艺，以及最终的污泥处置。
城市污水处理工艺目前仍在应用的有一级处理、二级处理、深度处理，但国内外最普遍流行的是以传统活性污泥法为核心的二级处理。
城市污水处理工艺的确定，是根据城市水环境质量要求、来水水质情况、可供利用的技术发展状态、城市经济状况和城市管理运行要求等诸方面的因素综合确定的。
工艺确定前一般都要经过周密的调查研究和经济技术比较。
最近几年国内应用较多的有A-O或A-A-O工艺、SBR工艺、氧化沟工艺等类型。
A-O或A-A-O工艺也叫缺氧-好氧或厌氧-缺氧-好氧工艺。
这一工艺的开发主要是为了满足脱氮除磷的需要，这是一种经济有效的生物脱氨除磷技术，我国南方不少污水厂就采用这一工艺。

2万m3d污水处理厂设计
设计任务书一．设计任务：某区2万m3/d污水处理厂设计二．任务的提出及目的要求：（一）任务的提出及目的：随着经济飞速发展，人民生活水平的提高，对生态环境的要求日益提高，要求越来越多的污水处理后达标排放。
在全国乃至世界范围内，正在兴建及待建的污水厂也日益增多。
有学者曾根据日处理污水量将污水处理厂分为大、中、小三种规模：日处理量大于10万m3为大型处理厂，1-10m3万为中型污水处理厂，小于1万m3的为小型污水处理厂。
近年来，大型污水处理厂建设数量相对减少，而中小型污水厂则越来越多。
如何搞好中、小型污水处理厂，特别是小型污水厂，是近几年许多专家和工程技术人员比较关注的问题。
通过城市中小型污水处理厂工艺的选择、设计，培养环境工程专业学生利用所学到的水污染控制理论，系统的掌握污水处理方案比较、优化，各主要构筑物结构设计与参数计算，主要设备造型包括格栅、提升泵、鼓风机、曝气器、污泥脱水机、砂水分离器、刮泥机、水下搅拌器、淹没式循环泵、加药设备、消毒设备等，以及平面布置和高程计算。
然后根据所确定的工艺和计算结果，绘制污水处理厂总平面布置图，管线总平面布置图、工艺流程图及各主要构筑物图10~12张。
（二）要求①方案选择合理②参数选取与计算准确③处理系统布置紧凑④所选设备质优、可靠、易于操作⑤图纸绘制达到施工图要求⑥概算部分尽量准确，详细三．设计基础资料A市是某省的重要工业城市，以重工业为主体，b区为其重要的工业及化工区，工业门类比较齐全，主要有一家铝厂、一家石油化工厂、一家热电厂、一家化肥厂、一家制药厂、一家农药厂、两家化工厂、一家合成纤维厂、一家电镀厂等。
b区为化工区，城镇人口有6万，目前每天排出污水量1.8万m3左右，污水BOD、COD、SS、酸、碱、有机磷、酚、氯化物、硫化物、石油、苯、三氯乙醛、四醇、铬离子等浓度较高，大都未经处理（或处理效果不好）直接排入c河。
根据规划，决定从b区起埋设新的污水总管收集工业污水和生活区的生活污水，在c河畔建设一座污水处理厂。

我国水体污染主要来自两方面，一是工业发展超标排放工业废水，二是城市化中由于城市污水排放和集中处理设施严重缺乏，大量生活污水未经处理直接进入水体造成环境污染。
工业废水近年来经过治理虽有所减少，但城市生活污水有增无减，占水质污染的51%以上。
本设计要求处理水量为28000m3/d的城市生活污水，设计方案针对已运行稳定有效的A2/O活性污泥法工艺处理城市生活污水。
A2/O工艺由于不同环境条件，不同功能的微生物群落的有机配合，加之厌氧、缺氧条件下，部分不可生物降解的有机物（CODNB ）能被开环或断链，使得N、P、有机碳被同时去除，并提高对CODNB的去除效果。
它可以同时完成有机物的去除，硝化脱氮、磷的过量摄取而被去除等功能，脱氮的前提是NH3+－N应完全硝化，好氧池能完成这一功能，缺氧池则完成脱氮功能。
厌氧池和好氧池联合完成除磷功能。

辽宁省WF市排水工程规划及污水处理厂设计第一章设计任务与内容1.1 前言在我国城市和工业飞速发展的今天，污水排放量与日俱增。
据统计，我国城市污水年排放量达400多亿立方米，现已有一批城市兴建了污水处理厂，一大批工业企业建设了工业废水处理厂，更多的城市和工业企业在规划、筹划和设计污水处理厂。
但这些污水处理厂几乎全在近100个大城市中。
近几十年来，污水处理技术无论在理论研究方面还是在应用方面，都取得了一定的进步，新工艺、新技术大量涌现，氧化沟系统和高效低耗的污水处理技术，如各种类型的稳定塘,AB法工艺,间歇式（序列式）活性污泥法,脱氮、脱磷的A-O系统，湿地系统都取得了长足的进步和应用。
这些新工艺、新技术已成为水污染防治领域的热门研究课题。
在国家科委、建设部、国家环境保护局的组织和领导下，广泛、深入地开展了这些课题的科学研究工作，取得了一批令人瞩目的研究成果。
不应回避，我国水资源严重短缺，我国人均水资源为世界人均水资源的四分之一，在我国北方一些城市人民生活水平的提高和工农业生产的发展已受到水资源不足的制约。
城市污水和工业废水回用，以城市污水作为第二水源的趋势，不久将成为必然。
这就是我国污水事业面临的现实。
作为给水排水工程专业的学生，就更应该深刻地了解这种形势，掌握并发展污水处理的新工艺、新技术，成为跨世纪的工程技术人才，将我国的污水处理技术达到世界领先水平。

第一章设计说明书1.1城市污水处理概论城市污水处理是指为改变污水性质，使其对环境水域不产生危害而采取的措施。
城市污水处理一般分为三级：一级处理，系应用物理处理法去除污水中不溶解的污染物和寄生虫卵；二级处理，系应用生物处理法将污水中各种复杂的有机物氧化降解为简单的物质；三级处理，系应用化学沉淀法、生物化学法、物理化学法等，去除污水中的磷、氮、难降解的有机物、无机盐等。
至于采取哪级处理比较合理，应视对最终排出物的处理要求而定。
城市污水处理技术就是利用各种设施设备和工艺技术，将污水所含的污染物质从水中分离去除，使有害的物质转化为无害的物质、有用的物质，水则得到净化，并使资源得到充分利用。
城市污水处理技术通常有物理处理技术、化学处理技术、物理化学处理技术、生物处理技术等。
典型的物理处理技术在城市污水处理中应用的有沉淀技术、过滤技术、气浮技术等。
典型的化学处理技术和物理化学处理技术有中和、加药混凝、离子交换等。
典型的生物处理技术有好氧牲氧化分解和厌氧生物发酵技术。
城市污水处理工艺，实际上是以上这些技术的应用与组合。
城市污水处理工艺：城市污水处理工艺按流程和处理程序划分，可分为预处理工艺，一级处理工艺、二级处理工艺、深度处理工艺和污泥处理工艺，以及最终的污泥处置。
城市污水处理工艺目前仍在应用的有一级处理、二级处理、深度处理，但国内外最普遍流行的是以传统活性污泥法为核心的二级处理。
城市污水处理工艺的确定，是根据城市水环境质量要求、来水水质情况、可供利用的技术发展状态、城市经济状况和城市管理运行要求等诸方面的因素综合确定的。
工艺确定前一般都要经过周密的调查研究和经济技术比较。
最近几年国内应用较多的有A-O或A-A-O工艺、SBR工艺、氧化沟工艺等类型。
A-O或A-A-O工艺也叫缺氧-好氧或厌氧-缺氧-好氧工艺。
这一工艺的开发主要是为了满足脱氮除磷的需要，这是一种经济有效的生物脱氨除磷技术，我国南方不少污水厂就采用这一工艺。
