| 摘 要： | 利用人工湿地模拟开展城市生活污水处理后二级水深度处理研究,发现人工湿地可以实现二级水的进一步处理,有效提升水质.选用西部地区常见的6种植物,利用箱培养开展不同植物在不同时期对水体COD,BOD5,NH4+-N处理效果的研究.研究显示,不同水生植物不同时期对不同污染物处理效率明显不同,8月份各类水生植物的处理效率最高,其中茭白对3类污染物的处理效率最高,菖蒲、芦苇处理效率较高,相对而言,慈姑的处理效率最低.因此利用天然湖泊或人工湿地可以进行城市生活污水的深度处理,开展污水治理过程中,水生植物的选择十分重要.

| Abstract: | A study on advanced water treatment of primarily treated municipal sewage by constructed wetlandreveals that constructed wetland is effective for treating secondary water and water quality can be considerably improved after the treatment.Six common aquatic plant species in West China were chosen to study theireffects of water treatment in different times using the three proxies of COD,BOD5and NH4+ -N.The studyshows that treatment efficiency of different plants on different wastes is very different in different times.Thetreatment efficiency of each species reaches its maximum in August.Among the six species,Zizania latifolia works most efficiently on the three wastes.The treatment efficiencies of Acorus calamus Linn andPhragmitescommunis Trirn are medium.Sagittariasagittifoliais the least efficient.Natural lake and constructed wetland can be used for advanced treatment of municipal sewage.Aquatic plant selection is very important for the treatment process. |
