    Northern rural domestic sewage treatment by integrated household constructed wetlands

    • A ten months continuous study (covering winter period) was conducted on an integrated household constructed wetland system for rural wastewater treatment. With a 0.5 m of biomass thermal insulation layer on the top of the system, the system temperature remained above 7℃ while the lowest climate temperature of -15℃, guaranteeing the ordinary treatment efficiency. The removal rates of COD, BOD5, NH3-N, TP, TSS, and turbidity were 93.0%, 96.0%, 88.4%, 87.7%, 97.0% and 89.6%, respectively. The effluent concentrations were 36.0, 11.8, 3.5, 0.6, 3.8 mg/L and 9.1NTU, respectively. The perfect removal efficiency of integrated household constructed wetland proved its potential application in the rural areas for the distributed wastewater treatment and environment protection.
