摘要
通过对巢湖农村地区进行调研,测算了农村生活污水产排污系数,并分析了不同污水处理模式的效果和适用条件。结果表明:该地区农村生活污水的平均产生量和排放量分别为26.31、16.31 L/(人.d),COD、TN、NH4+-N和TP的产污系数分别为18.91、0.63、0.16、0.08 g/(人.d),相应的排污系数分别为11.72、0.39、0.10、0.05 g/(人.d)。测算污水产量平均值为实测平均值的45%,COD、TN、TP换算浓度分别为实测平均值的151%、51%和74%。另外,实例分析表明,厌氧发酵(沼气)/人工湿地工艺、厌氧/生物接触氧化或曝气池/水生生物塘工艺、厌氧/人工湿地/水生生物塘工艺等以生物处理与生态处理相结合的污水处理技术可在农村地区推广使用。
The production and discharge coefficients of rural domestic sewage in the Chaohu area were estimated. The efficiency and suitable condition of sewage treatment modes were analyzed. The results showed that the average production and discharge quantity of rural domestic sewage in this area were 26.31 and 16.31 L/（person·d）, respectively. The production coefficients of COD, TN, NH4 -N and TP were 18.91, 0. 63,0. 16 and 0. 08 g/（person·d）, respectively, and the corresponding dis- charge coefficients were 11.72, 0.39, 0.10 and 0.05 g/（person·d）. The average estimated sewage production was 45% of the measured value, and the calculated concentrations of COD, TN and TP were 151% , 51% and 74% of the measured values. In addition, sewage treatment technologies that combine biological and ecological treatments, such as anaerobic fermentation （biogas）/eonstrueted wetland, anae-robie/bio-eontaet oxidation or aeration tank/aquatic pond, anaerobic/wetland/aquatic pond, can be widely used in rural areas.
