摘要
以济南水质净化二厂为例分析DE型氧化沟处理城市污水的效果,对该厂2004年水质指标CODCr、BOD5、SS、TP、NH3-N的进出水浓度变化进行了分析,同时分析了1#氧化沟和3#氧化沟的MLSS、MLVSS、SV的月平均变化趋势。结果表明用DE型氧化沟处理城市污水具有较好的效果,能够达到《城镇污水处理厂污染物排放标准》(GB18918—2002)的二级标准。
DE-type oxidation ditch was adopted for municipal wastewater treatment at Jinan No.2 Water-Purification Plant, Shandong Province. The average concentration records of 2004 for COD_ Cr , BOD_5, SS, TP and NH_3-N of influent and effluent, also the MLSS, MLVSS and SV of channel 1 and channel 3 of the oxidation ditch in this plant were investigated. The results showed that the DE oxidation ditch worked well, and the output water reached the class Ⅱ of the Discharge standard of pollutants for municipal wastewater treatment plant(GB 18918—2002).
