摘　　要：运用生物转盘+碎石湿地系统处理某北方农村污水,设计处理水量400 m^(3)/d,实际运行结果表明,对农村污水处理效果明显。原水ρ(CODCr)≤200 mg/L,ρ(NH3-N)≤40 mg/L,ρ(TP)≤4 mg/L时,系统对CODCr,NH3–N,TN和TP的平均去除率分别为78.98%,92.02%,69.44%和87.98%,出水主要指标满足DB 13/2795—2018《大清河流域水污染物排放标准》一般控制区排放限值,具有较强的耐冲击能力。项目每年削减CODCr23.36 t, NH3-N 5.548 t,TP0.38 t,明显改善了河道的生态环境。A system of ecological gravel bed and constructed wetland has been developed to treat rural sewage with a processing capacity of 400 m^(3)/d.The collected results demonstrated that this system/design significantly improved the rural sewage.When the COD,ammonia nitrogen and TP of raw water was no more than 200.0 mg/L,40 mg/L and 4 mg/L,the average removal rates of COD,ammonia nitrogen,TN and TP were 78.98%,92.02%,69.44%and 87.98%respectively.The major indices meet Daqing River Basin Water Pollutant Discharge Standard(DB 13/2795-2018).This system has exhibited robust treatment capabilities in processing waterways with a wide spectrum of qualities.This project is estimated to reduce Cod,nitrogen,and TP by 23.36 ton,5.548 ton,and 0.38 ton respectively annually,which significantly improved the ecological environment of the main channel in City.
