Research on the Treatment of High Concentration Sewage from Excrement Collector
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.
