A^2/O工艺在污水处理厂的应用

Applications of Anaerobic-Anoxic-Oxic Process in Wastewater Treatment Plant

分析了某污水处理厂污水处理主要工艺,重点研究了主要构筑物、工艺流程、工艺参数等。污水先经物化处理,然后利用A2/O工艺处理,最后再经物化处理。运行结果表明,工艺对COD等去除效果良好,达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级B标准。

The process of YunTing sewage treatment plant has been mainly analysed.the main structures,process control,and Process parameters have been mainly studied.The wastewater was firstly treated by the physicochemical process,then by the anaerobic-anoxic-oxic biological process,finally by the physicochemical process.Results showed that the process was efficient in removal of COD and the effluent can meet the standard of first A class of＂Municipal Wastewater Treatment Plant discharge standards＂（GB18918-2002）.
