ABR-生物接触氧化法处理乌鲁木齐小区生活污水

Study on Urumqi Domestic Sewage Treatment by ABR-biological Contact Oxidation Process

采用ABR-生物接触氧化组合工艺处理乌鲁木齐市华清园小区生活污水,对各构筑物进出口COD、BOD5、SS和氨氮进行40天运行监测,结果显示:此工艺对污染物的去除效果良好,运行稳定后,COD、BOD5、SS和NH3-N的去除率分别为86.5%、92.3%、93.3%和78.3%,出水水质达到城市绿化用水标准。研究分析了ABR-生物接触氧化组合工艺在生活污水处理中的反应机理、优势、设计特点以及运行参数。为经济高效地处理生活污水提供了理论依据。

Use ABR- biological contact oxidation combined process for Urumqi Huaqing Park District sewage,the operation of various structures import and export,such as COD,BOD5,SS and ammonia nitrogen,were monitored in 40 days,the results showed that this process worked well for pollutant removal operation after stabilization,COD,BOD5,SS and NH3- N removal rate were 86. 5%,92. 3%,93. 3% and 78. 3%,urban green water effluent quality met the standards. The reaction mechanism in sewage treatment ABR- biological contact oxidation combined process,benefits,design features and operating parameters was analyzed. Economic and efficient handling of domestic wastewater provided a theoretical basis.
