摘　　要：某开发区污水处理厂主要接收园区的化工废水和少量生活污水,针对污水成分复杂、难降解有机物多、可生化性差的特点,采用水解酸化/多段多级AO/臭氧氧化/曝气生物滤池/高效混凝沉淀/纤维转盘过滤的组合处理工艺。运行实践表明,该工艺运行稳定,处理效果良好,出水水质满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准,运行成本为1. 89元/m^3。The wastewater treatment plant in a development zone mainly received chemical wastewater and a small amount of domestic wastewater. Due to the complex composition of wastewater with many refractory organic matter and poor biodegradability, the combined process of hydrolysis acidification/multi-stage and multi-level AO/ozonation/biological aerated filter/coagulation reaction/high efficiency precipitation/fiber rotary filter was used. The actual operation results showed that the effluent quality of the sewage treatment plant was stable and met the first level A criteria in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant ( GB 18918-2002 ). Its unit operating cost was 1.89 yuan/m^3.
