摘要
从潼湖地区村镇污水的特点及居民的生活习惯出发,构建了处理能力为100 m3/d的原位生态修复示范工程,通过植生混凝土滤槽/给水污泥人工湿地/人工浮岛组合工艺处理潼湖水系黄屋村污水,以实现对污水的净化和水环境原位生态修复。监测数据表明,进水TN、TP、COD、NH+4-N平均浓度分别为53.3、4.77、90.23、41.61 mg/L,相应的出水平均浓度为7.36、0.75、31.23、3.76 mg/L,平均去除率分别为86.59%、84.06%、65.43%、91.09%。出水COD、NH+4-N、TN浓度达到了《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准,TP达到了一级B标准。这对于南方地区村镇污水的处理具有一定的工程示范作用和推广应用价值。
Based on the characteristics of rural sewage and living habits of residents in Tonghu area, an in-situ ecological restoration demonstration project with capacity of 100 m^3/d was built. To realize biological treatment of rural sewage and in-situ ecological restoration of water environment, the combined processes of planting concrete filter tank, waterworks sludge constructed wetland and artificial floating island was applied. The monitoring data showed that the average concentrations of TN, TP, COD and NH4 - N were decreased from 53.3 mg/L, 4.77 mg,/L, 90.23 mg/L and 41.61 mg/L to 7.36 mg/L, 0.75 rag/L, 31.23 mg/L and 3.76 mg/L, and the average removal rates were 86.59% , 84.06% , 65.43% and 91.09% respectively. The effluent concentrations of COD, NHf -N and TN could meet the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002）, while the effluent concentration of TP could meet the first level B criteria. It is certainly valuable in engineering demonstration and application for rural sewage treatment in the southern area.
