摘要
对西安市北石桥污水净化中心DE型氧化沟系统各阶段处理效果进行了实测 ,结果表明DE型氧化沟处理城市污水效果显著。COD、TN、TP的总去除率分别达到 87 5%～ 91 6 %、6 3 6 %～ 6 6 9%、85 0 %～ 93 4% ,处理水质优于国家二级出水排放标准。
The treatment efficiency of the DE oxidation ditch was investigated in Beishiqiao Wastewater Treatment Center in Xi'an. The result shows that the system has achieved a removal of COD, TN and TP as high as 87.5%～91.6%, 63.6%～66.9% and 85.0%～93.4% respectively and the effluent quality is better than the class II of the National Standard. One of the principal features of this system is utilizing the high adsorption ability of sludge in the selective basin and the decomposition ability of bacteria in the oxidation ditch to achieve high removal of organic and nutrient matters.
