江苏苏州天通一体化污水处理设备
工程概况 
本污水处理系统污水来源为生活污水，生活污水如果直接排放会污染周边环境，因此必须对排放的污水进行处理，使处理后的排放水达标排放。  根据实际情况，针对本处理工程，在处理工艺上采用AO处理技术，工艺成熟，处理效果好，处理后的排放水可达到国家《污水综合排放标准》（GB8978-1996）一级排放标准。
 
设计依据 
1、《城市区域环境噪声标准》（GB3096-93）； 2、《室外排水设计规范》（GBJ14-87）； 3、《给水排水工程结构设计规范》（GBJ69-84）； 4、《污水综合排放标准》（GB8978-1996）。
 
设计范围 
污水处理站范围内的污水处理建（构）筑物及配套建（构）筑物的工艺、土建、电气、仪表及供电线路及进出水管线的设计。
 
工艺选择
水质浓度不高且稳定，可生化性较好，属可生化污水。工艺确定 
工艺可分为生物挂膜法和活性污泥法。生物挂膜法一般适用于水量较小、水质较为稳定、浓度不高的污水水质，同时由于生物膜培养较快系统调试好后运行稳定，可操作性较强。
 
由于污水中氨氮和**物含量较高，建立调节池的目的是调节污水的数量和质量。A级池的生化作用后，仍存在一定量的**质和较高的氮和氨氮污水中。为了进一步氧化和分解**物，同时，当炭化效果趋于完整时，硝化反应可以顺利进行。特别是在生物**物氮、**物、氨氮等**物的生物降解中，氨氮也是污染控制的重要指标之一，因此污水处理采用厌氧好氧A/O生物接触氧化工艺，生化池需要分为池池和O池两部分。
Design scope
The design of sewage treatment, construction, construction and construction, construction, electrical, instrument, power supply line and inlet and outlet water line of sewage treatment station.

Process selection
The water quality is not high and stable, and it can be biodegradable, which is a biodegradable sewage. Process determination
The process can be divided into biological membrane method and activated sludge process. Biofilm is generally suitable for sewage with small water quality, stable water quality and low concentration. At the same time, because biofilm culture is faster and system debugging is good, operation is stable, and operability is strong.

Because of the high content of ammonia nitrogen and organic matter in the sewage, the purpose of setting up the regulating pool is to adjust the quantity and quality of the sewage. There is still a certain amount of organic matter and higher nitrogen and ammonia nitrogen sewage after the biochemical action of the A-level pool. In order to further oxidize and decompose organic matter, the nitrification reaction can be carried out smoothly when the carbonization effect tends to be complete. Especially in the biodegradation of organic compounds, such as nitrogen, organic matter and ammonia nitrogen, ammonia nitrogen is also one of the important indicators of pollution control. Therefore, the anaerobic aerobic A/O biological contact oxidation process is applied in wastewater treatment. The biochemical pool needs to be divided into two parts: pool pool and O pool.
