摘　　要：本文构建了一种分散式农村生活污水净化槽,研究了净化槽在不同水力停留时间、进水水质、填料等运行条件下对模拟污水中化学需氧量(COD)、氨氮(NH;-N)、总磷(TP)3项指标的去除效果。结果表明,净化槽对模拟污水的处理效果较好,具有一定的可行性和实用价值。对COD的去除效果最好,出水COD达到山东省《农村生活污水处理处置设施水污染物排放标准》二级标准。在各种填料中,腐殖土对磷的吸附效果最好,陶粒次之。In this study, a decentralized rural domestic sewage purification tank was constructed, the removal efficiency of three indicators of chemical oxygen demand(COD), ammonia nitrogen(NH;-N) and total phosphorus(TP) in the simulated sewage was studied under different operating conditions,such as hydraulic retention time, influent quality and carrier. The results showed that the purification tank had a good effect on the treatment of simulated sewage, and it had certain feasibility and practical value. The removal efficiency on COD was the best, and the effluent concentration of COD reached secondary standard of Discharge Standard of Water Pollutants for Rural Sewage Treatment Facilities in Shandong Province. Among the several carriers, humus showed the best adsorption efficiency on phosphorus, followed by ceramsite.
