高浓度粪便污水处理技术研究

Research on the Treatment of High Concentration Sewage from Excrement Collector

高浓度粪便污水具有污染物浓度高、处理难度大等特点。采用“两级MBBR+磁混凝”工艺对高浓度粪便污水进行现场试验。经过“两级MBBR+磁混凝”处理后,粪便污水COD、TN、NH3-N和TP去除率分别为89.56%、95.76%、97.31%和95.15%,出水水质满足《污水排入城镇下水道水质标准》(GB/T 31962—2015)要求。试验结果表明,“两级MBBR+磁混凝”工艺可以有效处理高浓度粪便污水。

High concentration sewage of excrement collector has the characteristics of high pollutant concentration and difficulty in the treatment of sewage.The two-stage MBBR and magnetic coagulation process were used to treat the high concentration sewage.After two-stage MBBR and magnetic coagulation treatment,the removal rates of COD,TN,NH3-N and TP were 89.56%、95.76%、97.31%and 95.15%,respectively.The water quality of the water can meet the Wastewater quality standards for discharge of sewage to municipal sewers(GB/T 31962—2015).The test results show that the two-stage MBBR and magnetic coagulation process can effectively treat high concentration of sewage.
