摘要
瑞安市污水处理厂采用A-A2O氧化沟工艺,该工艺具备好氧、兼氧和厌氧等多种环境,适合微生物生长。一期工程自2007年运行以来,日处理污水量逐年上升。2008—2010年的水质检测数据显示,A-A2O氧化沟对CODcr、氨氮等机污染物的去除率较高,可达90%以上;对总氮、磷等污染物的去除率相对较低,但不影响飞云江水质。3年检测数据表明:该处理厂的出水水质良好,处理工艺基本合理。
The A-A2O oxidation ditch technology is adopted in the sewage treatment plant of Ruian city,which has the many environment of aerobic,facultative and anaerobic to meet the microbiology growth.The daily capacity of sewage treatment increases year by year since the operation of the first phase project in 2007.The water quality data between 2008 and 2010 shows that the removal rate of CODCr,ammonia and nitrogen pollutant is up to 90% and the removal rate of total nitrogen and phosphorous pollutant is lower relatively,but it not affects water quality of Feiyun river.The 3 years test data show that the water quality of the plant output is good and the technology is rational basically.
