平顺县污水处理厂设计
摘要
水资源是我们的生命之源，水资源有限，但人口数量却在不断上升，水体被污染水资源短缺变成我们面临的巨大问题，如何对水资源保护和处理被污染水资源并回收再用成为一个重要课题。
平顺县是山西省长治市下辖县，位于山西省东南部，长治市东部，地处太行山脉南段西半侧，是典型的干石山区和革命老区。
其地势东南高，西北低，属暖温带大陆性季风气候，其境内有神龙湾天瀑峡、太行水乡、通天峡等旅游景点，曾获得“电子商务进农村综合示范县”等荣誉称号。所以使用SBR工艺设计一个荣成市的污水处理厂。
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。

City14500m3/d sanitary sewage SBR of Pinshun deals with technological design
Abstract
Water resources are the source of our life. Water resources are limited, but the population is increasing. The shortage of polluted water resources has become a huge problem we are facing. How to protect and treat polluted water resources and how to recycle them has become an important topic.
Pingshun County is a county under the jurisdiction of Changzhi City in Shanxi Province. It is located in the southeast of Shanxi Province and in the east of Changzhi City. It is located in the western half of the southern section of Taihang Mountains. It is a typical dry mountain area and an old revolutionary base area. Its terrain is high in the southeast and low in the northwest. It has a continental monsoon climate of warm temperate zone. Its tourist attractions such as Tianbao Gorge in Shenlongwan, Taihang Watertown and Tongtian Gorge have won the honorary title of "E-commerce into Rural Comprehensive Demonstration County". Therefore, SBR process was used to design a wastewater treatment plant in Pingshun County
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 sediment to react. On main characteristic of it operate in order and intermittence operate, core, SBR of technology that SBR reacts in the pool, this pool collects melting , sinking for the first time , function that biodegradation , two sink ,etc. in one pond, there is no mud backset current system. Can reach the designing requirement through the waste water of this waste water treatment craft , can discharge directly . Mud that produce after concentrating , pressing and straining etc. dealing with , go on compost produce sure economic benefits.
