本设计是某城市污水处理厂的初步设计.设计处理污水为工业废水与生活用水的城市混合污水,处理规模171600m3/d.主要任务是工艺流程选择及构筑物的设计和计算.
本设计采用A2O工艺.该工艺是最简单的同步脱氮除磷工艺,总水力停留时间短.在厌氧好氧交替运行条件下,丝状菌不能大量增殖,不易发生污泥丝状膨胀.污泥含磷高,具有较高肥效,易于解决污泥的处理问题.此外,该工艺还具有运行费用低等优点.
污水处理厂处理后的出水达到国家《城镇污水处理厂污染物排放标准》（GB18918-2002)一级B标准.

This design is the preliminary design of a city sewage treatment plant. The design of city sewage treatment sewage for industrial wastewater and domestic water, deal with the scale of 171600m3/d. The main task is to design and calculate the selection and construction process.
This design uses the A2O process. This is the process of simultaneous nitrogen and phosphorus removal process is the most simple, short hydraulic retention time. In the anaerobic aerobic conditions, filamentous bacteria could not proliferate, less sludge bulking. Sludge high phosphorus content, high efficiency, easy to solve the problem of sludge treatment. In addition, the process has the advantages of low operating costs.
The effluent from a sewage treatment plant after treatment up to the national "urban sewage treatment plant pollutant discharge standard" (GB18918-2002) is a B standard.
