活性污泥法与工业废水处理 摘要 随着社会和经济的发展，中国的工业化程度与水平不断提高，工业废水规模不断增加，水污染问题逐渐严重。

大量工业废水未经处理直接排入环境，污染了大量水资源，加剧了我国水资源的紧缺。

近年来，国家日益重视水环境污染状况，加大了对水污染防治设施的建设投入。

由于处理率高、运行成本低、操作简单等特点，活性污泥法成为工业废水处理常用的方法之一，常见的活性污泥法有AAO、氧化沟、CAST和MBR工艺。

本文将对以上活性污泥法进行详细介绍，并进行比选，选择出本例中工业园区污水处理的主工艺。

Key words:industrial park sewage treatment；activated sludge process;AAO process;oxidation ditch;CAST process;MBR process 1.前言 随着社会和经济的发展，中国的工业化程度和水平越来越高。

但是与此同时工业化带来的水污染问题也愈发显著。

随着水资源的短缺和水体污染的加剧，各个国家对于水体保护的要求也日益提高，制定了更加严格的污水处理和排放标准，从”量”和”质”两方面对污水处理和排放提出了更为严格的要求[1]。

以本设计中的乌鲁木齐高新区甘泉堡工业园区的污水处理项目为例，因服务范围内有新材料、煤化工、机械、建材、化工等企业，故进水水质较常规的生活污水浓度高。

工程出水水质执行一级A排放标准。
