污水土地处理系统填料的研究进展

The Advances of soil filler in sewage land treatment

填料是土地处理系统中处理污水的关键组成,其性能决定出水水质的好坏。土壤颗粒的大小结构、有机质含量及矿物质均对污水中污染物的降解有着重要的作用。虽然天然土壤本身就具有良好的除污性能,但是处理规模和质量不能满足目前的需求,且存在易堵塞、有机负荷低的缺陷,而各种人工土壤和填料的出现则强化了其性能并解决了天然土壤存在的一些问题。本文对土地处理系统中人工土和填料的研究现状进行了综述,并对未来的发展提出了展望。

the filler is the key composition in the land treatment eatment.its performance can determine the quality of the effluent.the size,struture,organic content and mineral of the filler are the main factors in the breakdown of the contaminant in the sewage.even the nature soil can deal with the sewage well,but can not content the demands in the scale and quality.it can be easily colgged and take lots of speace.while the new filler and the manmade soil enhance the sewage treatment and to solve some problems of n...
