摘　　要：利用构建的复合人工湿地系统,对邯郸市城市污水进行了长期净化试验,探讨了秋冬季节系统对污水的净化效果。试验结果表明,秋季系统对COD、TN、TP、SS的去除率分别为65%、86%、80%和91%,冬季下降为25%、27%、65%和89%。经过二级子系统串联后,净化效果明显提高且系统稳定性增强。The test on treating urban sewage in Handan has been continuing for a long- term by using the composite constructed wetland system, and the purification effect were discussed in autumn and winter. The results show that the removal rates of COD, TN, TP, SS are 55 %, 84 %, 80 %, 91%, in winter drop off to 25 %, 27 %, 65 %, 89 % in autumn. The purification effect and stability of system have been raised during the serial secondary sub - series.
