Abstract: | [Objective] To analyze the topography of Sichuan hilly areas and the characteristics of rural domestic sewage in reconstruction region.[Method] The methods of A/O and artificial wetlands were combined to treat rural domestic sewage.[Result] Operating at 22 h hydraulic retention time of A/O and a hydraulic loading rate of 0.6 m3/(m2·h),under the average concentrations of COD≤60 mg/L,NH3-N≤8 mg/L,TP≤1.0 mg/L,SS≤20 mg/L in the effluent,the average removal efficiencies of COD,NH3-N,TP and SS were 81.4%,84.1%,83.3% and 90.0%,respectively.[Conclusion]The effluent indexes could reach the first level B discharge criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002). |
