摘　　要： 选取石英砂、煤灰渣和高炉渣作为介质,再按适当的比例配以有机质和土壤组成人工土填料处理柱,进行了不同基质垂直流人工湿地对城市污水的净化效果研究。为期1a多的运行试验结果表明,煤灰渣基质对化粪池出水中COD、BOD5和TP的去除率分别达到71%～88%、80%～89%和70%～85%。高炉渣基质对化粪池出水中COD和BOD5的去除率分别为47%～57%和70%～77%,但对总磷的去除率高达83%～90%。石英砂基质虽然对化粪池出水中COD、BOD5和TP的去除率分别为36%～49%、65%～75%和40%～55%,但其导水能力最好,水力负荷最高。 We used quartz sand, cinder residue, steel furnace slag as filtering media according to proper proportion compound with organic matter and soil for sewage treatment for a period of over one year. The results of operation showed that the removal rates of COD, BOD5, and TP were 71%～88%, 80%～89%, and 70%～85%, respectively by cinder residue for treating septic tank effluent. The removal rates of COD and BOD5 by steel furnace slag were 47%～57%and 70%～77%, but the removal rate of total phosphorus was high up to 83%～90%. Although the removal rates of COD, BOD5 and TP were 36%～49%, 65%～75%and 40%～55%, respectively by quartz sand, the hydraulic conductivity and hydraulic loading rate was the highest among the three substrates.
