摘　　要：研究了200、500、1 000 mm/d 3种不同水力负荷条件下人工湿地-稳定塘组合系统对污水中污染物的处理效果,分析了组合系统的抗污染负荷能力。研究表明,水力负荷对人工湿地-稳定塘组合系统处理生活污水的去除效果有较大的影响,随着水力负荷的降低,去除率逐渐升高。COD_(Cr)、TN、NH_4^+-N去除率分别达到72.09%、51.68%、62.54%,组合系统具有较好的抗污染负荷冲击能力,出水能保持相对稳定。The effects of the combined system,constructed wetland-stabilization pond on the removal of pollutants from sewage under three kinds of hydraulic loads(200,500,and 1 000 mm/d,respectively) conditions have been studied,and the anti-pollution load capacity of the combined system analyzed. The results show that hydraulic loads have great influence on the removing capacity of the combined system,constructed wetland-stabilization pond,for treating domestic sewage. With the decrease of hydraulic load,the removing rate increases gradually. The removing rates of COD_(Cr)、TN、and NH_4^+-N can reach 72.09%,51.68%,and 62.54%,respectively. The combined system has pretty good capacities of anti-pollution load and shock resistance. The effluence remains relatively stable.
