A/O+A/O两级生物接触氧化工艺处理工业区废水

Application of A/O+A/O biological contacted oxidation process to the wastewater treatment in industrial districts

以如皋某工业区废水处理中心为例,介绍了A/O+A/O两级强化生物接触氧化工艺处理工业区废水的工程设计。设计处理规模为20000m3/d,进水COD为500mg/L,处理后出水达国家一级排放标准,并在两级A/O强化池中构建了生态系统,为工业区废水的综合治理和利用提供了一条较好的途径。

An industrial wastewater treatment center in Rugao is taken as an example.The engineering design of A/O+A/O couple strengthening biological contacted oxidation process for the wastewater treatment in industrial districts is introduced. The scale of this treatment design is 20 000 m3/d, and the inlet water COD is 500 mg/L. After the treatment,the outlet water can reach the first grade of discharge standard of China. Besides, an ecological system has been set up in the A/O couple strengthening pond, providing a good approach to the comprehensive control and utilization of industrial district wastewater.
