在城市污水处理厂A_2O系统中硅藻土对除磷的影响

The Impact of Diatomite on Phosphorus Removal on the municipal Sewage Plant using A_2O

为考察硅藻土对城市污水处理厂除磷的影响,以辽宁朝阳某城市污水处理厂A_2O处理系统为研究对象,重点分析了硅藻土的微观结构,投加硅藻土对A_2O处理系统MLSS、MLVSS、MLSS/MLVSS、微生物及磷去除率的影响。结果表明,硅藻土具有多孔结构,在A_2O处理系统中投加硅藻土能够显著提高MLSS、MLVSS、MLSS/MLVSS,微生物明显也增多,且有助于对磷的去除。

In order to understand the impact of diatomite on phosphorus removal in the municipal Sewage plant, a certain municipal Sewage plant using A2 O, in Chaoyang City Liaoning Province as research target. The microstructure of diatomite was analyzed, the effect of dosing diatomite on MLSS, MLVSS, MLSS/MLVSS, microbial structure,the phosphorus removal rate was studied. The results show that diatomaceous has a porous structure, MLSS, MLVSS, MLSS/MLVSS increased significantly, microbial also increased, and contributed to removal phosphorus.
