摘要
将人工湿地技术与生物接触氧化法相组合的生物净化槽应用于上海市中心城区黑臭河水净化.试验结果表明,生物净化槽对系统中BOD5、CODCr、NH3-N和TP的平均去除率分别为37.0%,34.8%,34.7%,26.7%,去除率高于单一的填料净化槽.海寿花的同化利用对N、P的去除贡献率分别为8.92%,25.24%,并与微生物间形成了良好的互惠共生关系.生物膜挂膜动态分析检测结果表明,生物净化槽能够较好地实现对黑臭水体生态系统的修复.
The biological purification tank combined of artificial wetland technique and the bio-contact oxidation method was applied for malodorous river water in central urban region of Shanghai City. The average removal rates of Pontederia cordata L filling filtering tank on system BOD5, CODCr, NH3-N and TP were 37.0%,34.8%,34.7%,26.7% respectively, the removal rates were higher than the filling purification tank. The devoted rates of Pontederia cordata L assimilate ufiUzation on N, P were 8.92% and 25.2.4% respectively, and formed good mutually beneficial and intergrowth relations. Through the analysis of biofilm, the ecosystem of water body has been remediated rapidly during the experiment.
