Engineering practice of inverted A2/O+A biochemical method+membrane method+magnetic coagulation combination process for wastewater treatment
A combination process of"inverted A2/O+A biochemical method+membrane method+magnetic co-agulation physicochemical method"is adopted to treat wastewater,and the process characteristics are ana-lyzed.The main structures and equipment parameters are also described in detail.The combined process has excellent treatment effect,with good phosphorus and nitrogen removals.The monthly average values of COD,TP,NH3-N and TN in the effluent are 28,0.2,0.3 and 6.06 mg/L,respectively,which reach the pollutant dis-charge standards of other regions in the Discharge Standard of Main Water Pollutants for Municipal Wastewa-ter Treatment Plant&Key Industries of Taihu Area(DB32/1072-2018).Among them,the three indicators of COD,TP and NH3-N also meet the specified Class IV water discharge standard of Environmental Quality Stan-dards for Surface Water(GB3838-2002).
