| 摘 要： | 利用人工湿地处理技术探讨城镇生活污水治理与利用,研究菖蒲、美人蕉、麦冬3种植物在水力停留时间分别为1、3、5、7 d时对城镇生活污水的净化效果。结果表明,3种植物中美人蕉的处理效果最好,麦冬较差。在水力停留时间为7 d、密度为10株/m2时美人蕉对BOD5、CODcr、TP和TN的去除率分别为92.3%、88.2%、94.9%、94.6%。人工湿地生态系统适合以生活污水为主的城镇污水处理。

| Abstract: | Urban domestic sewage in town would be an important water pollutant source as the process of urbanization.Sewage treatment and reuse had not address enough attention and needed to be solved.The artificial wetland processing technique was used to treat domestic sewage and reuse.The purification effect of three plant species,calamus,canna and liriope with hydraulic retention time 1,3,5,7 d was investigated.The results showed that canna had the best purification effect;while liriope was worse.When hydraulic re... |
