摘要
XX市地处山东半岛最东端，三面环海，海岸线长500公里。拥有石岛、龙眼两个一类开放口岸，山东省GDP排名第一的县级市（威海市代管）， 中国魅力城市，优秀旅游城市，生态园林城市，人居范例城市，环保模范城市，新兴工业强市，沿海开放城市，海洋经济大市，国家级海洋食品名城，人口较多。所以使用SBR工艺设计一个XX市的污水处理厂。
SBR是序列间歇式活性污泥法（Sequencing Batch Reactor Activated Sludge Process）的简称，是一种按间歇曝气方式来运行的活性污泥污水处理技术，又称序批式活性污泥法
与传统污水处理工艺不同，SBR技术采用时间分割的操作方式替代空间分割的操作方式，非稳定生化反应替代稳态生化反应，静置理想沉淀替代传统的动态沉淀。它的主要特征是在运行上的有序和间歇操作，SBR技术的核心是SBR反应池，该池集均化、初沉、生物降解、二沉等功能于一池，无污泥回流系统。经过这个废水处理工艺的废水可达到设计要求，可以直接排放。产生的污泥经过浓缩、压滤等处理后，进行堆肥产生一定的经济效益。

City25,000m3/d sanitary sewage SBR of Rongcheng deals with
technological design
Abstract
Rongcheng is located in the eastern tip of Shandong Peninsula, surrounded by the sea, a coastline of 500 km.Rongcheng has Shidao, longan which are one-class open port,and it is the first county-level city GDP rankings (Weihai City hosted) in Shandong Province.It was He was known as the Chinese charm of the city, excellent tourist city, eco-garden city, living examples cities, environmental protection model city, the emerging strong city, coastal open cities, the Great City National Ocean marine food city.However, it has lager population.So use the SBR process design of a sewage treatment plant in Rongcheng .
SBR is the abbreviation of the intermittence type active mud law (Sequencing Batch Reactor Activated Sludge Process ) of the array, it is one kind that exposes to the sun the active mud sewage treatment technology that the angry way operates according to the intermittence , also called the criticizing type law of active mud of preface.
Different from traditional sewage disposal craft, SBR technology adopt operation mode that time cut apart substitute operation mode that space cut apart, stabilize biochemistry is it substitute stable state biochemistry react , quiet to put ideal precipitate and substitute the traditional dynamic
