摘要：随着工业的发展和社会生活水平的提高，人们对水的需求量越来越大，直接导致工业废水和生活污水的量急剧上升。靠自然水体的自净能力已经远远不够。于是污水处理厂应运而生。污水处理工艺多式多样，本文只讲述SBR一法。SBR(Sequencing Batch Reactor)全称是间歇式活性污泥处理系统，又称序批式活性污泥处理系统。
近几十年来，电子工业发展迅速。污泥回流，曝气充氧以及混合液中的各项主要指标，入溶解氧、PH值、电导率、氧化还原电位等，都能够通过自动检测仪表做到自控操作，污水处理厂整个系统都能够做到自控运行。这样就为活性污泥处理系统的间歇运行在技术上创造了条件。
SBR法是通过时间上的安排，在一个池子内完成了进水、反应、沉淀和排水等一系列工艺过程，构成了一个周期。这种工艺近年来在我国已被广泛研究和应用。本文对国内已经实际运行的SBR及其几种变型工艺作些介绍，并着重介绍近年来发展的城市污水处理SBR技术。

Abstract：With industrial development and social improvement of living standards, people are increasing demand for water is a direct result of industrial wastewater and domestic sewage volume rose sharply. Self-purification capacity of natural water by far is not enough. So sewage treatment plant came into being. Wastewater treatment and more diverse style, tells SBR this is only one method. SBR (Sequencing Batch Reactor) stands for SBR treatment system, also known as sequencing batch reactor activated sludge treatment system.
In recent decades, the electronics industry has developed rapidly. Return sludge, aeration, and the major indicators of the mixture, into the dissolved oxygen, PH, conductivity, redox potential, etc., can be controlled by automatic detection instrument operation, the entire system of sewage treatment plant Can be controlled operation. This activated sludge treatment system is intermittent operation to create the conditions in the technology.
SBR method is through the timing, in a pond within the water, reaction, sedimentation and drainage and a series of process, form a cycle. China in recent years this process has been widely studied and applied. In this paper, the country has actually run some variant of SBR and its introduction to some process, and focuses on the development of urban wastewater treatment in recent years, SBR technology.
Keywords: SBR activated sludge integrated design method
污水处理的基本方法，就是采用各种技术与手段，将污水所含的污染物质分离去除、回收利用，或将其转化为无害物质，使水得到净化。
现代污水处理技术，按原理可分为物理处理法，化学处理法和生物化学处理方法。
物理处理法：利用物理作用分离污水中呈悬浮状态的固体污染物质。方法：筛虑法，沉淀法，上浮法，气浮法，过滤法和反渗透法等。
化学处理法：利用化学反应的作用，分离回收污水中处于各种形态的污染物质（包括悬浮的溶解的胶体的）。主要方法有中和、混凝、电解、氧化还原、汽提、萃取、吸附、离子交换和电渗析等。化学处理多用于处理生产污水。
生物化学处理法：是利用微生物的代谢作用，使污水中呈溶解、胶体状态的有机物转化为稳定的无害物质。主要方法可分为两大类，即利用好氧微生物作用的好氧法（好氧氧化法）和利用厌氧微生物的厌氧法（厌氧还原法）。前者广泛用于处理城市污水及有机性生产污水，其中有活性污泥法和生物膜法两种;后者多用于处理高浓度有机污水与污水处理过程中产生的污泥，现在也开始用于处理城市污水与低浓度的有机物。
