摘要
文章主要讨论了磁性活性污泥在废水处理中的作用机理,指出了在活性污泥中加入磁性粉末后,使活性污泥的结构得到了改善,污泥的沉降性能、污泥中微生物活性及抗污染物冲击负荷能力都优于普通活性污泥,并且使污泥对废水中的有机物、N、P等营养物质及重金属的去除效率有较大的提高。这主要与磁性粉末有较大比表面积及表面的键态、电子态有关。
This paper mainly discussed the Study of function mechanism of magnetic powder activated sludge in wastewater treatment industry, pointed out after magnetic powder was added in the activated sludge, in comparison with conventional ASP, magnetic powder activated sludge is better than ASP in relation to the sedimentation, microorganism activity and the permissive concentration of poisons. In addition, the removal of COD, N, P, Heavy Metal was compared to raise greatly. This mainly has re- lationship with the magnetic powder has specific surface area and surface of bonding state, electronic state.
