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。

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20000m3/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。

A2O工艺由于不同环境条件,不同功能的微)能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被开环或断链,使得N、P、有机碳被同时去除,并提高对COD的去除效果。

它可以同NB--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NH3N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。

摘要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。

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(COD NB)能被开环或断链,使得N、P、有机碳被同时去除,并提高对COD NB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。

工业废水占城市总废水量的20%,各工业废水经过处理达到国家标准后排入城市污水管网。

1.2.2排水系统雨水与污水采用分流制,生活污水与工业废水为合流制,污水处理厂只考虑处理生活污水与工业废水,输入污水厂的污水干管直径为1000mm ,管底埋深为地面以下5.3m ,充满度为0.5。
