固化微生物膜—植被渗滤法处理生活污水的研究

Study on the Treatment of Waste Water by Using Curing Microbial Membrane Combined with Vegetation Filtration System

利用废陶瓷固化微生物膜与植被渗滤联合系统,对模拟生活污水进行处理,分别研究其对CODCr、总氮、总磷的去除率,将其与单独使用固化微生物膜处理模拟生活污水比较,研究结果表明,将固化微生物膜—植被渗滤系统联合使用时,相当于二级处理模拟废水,经微生物利用部分污染物后,随后排放的水经植被渗滤系统,滞留其中且被植物吸收利用,使得CODCr、总磷、总氮去除率明显优于单独使用固化微生物膜的去除率。这对处理农村生活废水有一定帮助,有效减少水体富营养化。

Using waste ceramic curing microbial membrane uniting vegetation filtration system to process simulation sewage,and to study the removal rate of CODCr,total N and P severally.Then contrasting it to the exclusive use of curing microbial membrane.The results of the study showed when waste ceramic curing microbial membrane and vegetation filtration system are combined,it corresponds to the use of secondary treatment of simulation sewage.Using a part of pollutants by microorganisms,then waste water passes into vegetation filtration system,the pollutants were detained and absorbed by plants.So the removal rate of CODCr,total of P and N were superior than curing microbial membrane obviously.It was beneficial to the rural sewage treatment and reducing water eutrophication effectively.
