| 摘 要： | 采用由生物浮床、生物接触氧化以及河道生态系统构成的生态组合系统处理农村生活污水,考察了其对农村生活污水的净化效果以及季节和污水停留时间(HRT)对污染物的去除效果的影响。结果表明,该组合系统对污染物具有良好的去除效果,COD,NH4+-N,TN,TP的平均去除率分别为57.68%,51.13%,52.38%和49.02%。污染物的去除率随HRT的增加而提高,4 d后变化趋于平缓,在HRT为6 d时,NH4+-N,TN,TP和COD的去除率分别达到80.36%,72.85%,60.74%和71.97%。与秋季相比,夏季时该组合系统对NH4+-N,TN,TP的去除率相对较高,但季节变化对COD去除效果的影响不大。

| Abstract: | The combined eco-system of floating culture bed,biological contact oxidation process and the river eco-system was used to treat rural domestic sewage.The removal efficiency and the influence of the season and sewage retention time on pollutants removal were investigated.The results showed that the combined bio-system had good removal efficiency on pollutants.The mean removal rates of COD,NH4+-N,TN and TP were 57.68%,51.13%,52.38% and 49.02% respectively.The removal rate of pollutants increased greatly with ... |
