The application of reverse osmosis in the municipal sewage recycle to thermal power plants

The application of flat sheet MBR in treatment of municipal sewage is introduced,including basic process of MBR,tank volume calculation,filtration mechanism,energy saving measures,sludge age,membrane cleaning method and so on.

In this paper, the effect of heavy metals on the ability of phosphate accumulating bacteria purifying municipal sewage was studied by adding 4 kinds of solutions containing different contents of Cu~(2+), Zn~(2+), Cr~(6+), and Cd~(2+) to sewage.

The results of the investigation on sludge treatment systems over 400 municipal wastewater treatment plants in China show that only about 46 plants have sludge anaerobic digestion systems,most of which adopt thickening/mesophilic anaerobic digestion/dewatering process.
