摘　　要：针对某大型工业园综合污水氮磷含量高的特点,应用多点进水倒置A/A/O工艺处理该工业园排放的综合污水,通过改变内回流的回流点及回流比例,使倒置A/A/O工艺可以根据进水水质,既可按缺氧—厌氧—好氧顺序运行,也可按照厌氧—缺氧—好氧顺序运行,而多点进水方式可以有效地解决反硝化菌和聚磷菌对有机底物的竞争。采用该工艺处理后出水可达标排放。对该工程设计的主要设计参数及主要工艺设计特点进行了介绍。Aiming at the high nitrogen/phosphorus content in the integrated wastewater in an industrial park,the multi-site inverted A2/O process has been applied to the integrated wastewater treatment in an industrial park.The inner reflux point and reflux ratio are to be changed.Then,according to the influent water quality,the inverted A2/O process can be operated in sequence of anoxic-anaerobic-aerobic and can also be operated in sequence of anaerobic-anoxic-aerobic.The application of multi-site influent can solve the competitive substrate concentration between denitrifying bacteria and polyphosphate accumulating organisms.Every index of its effluent can reach the discharge standard.The main design parameters and main design characteristics of the engineering design process are introduced.
