Study on Treatment of Municipal Wastewater with Biochemistry Process

Abstract:

Treatment of municipal wastewater with biological/chemical process was studied in this paper. Chemical agents-polyaluninum sulfate was selected in this test to determine the effect on phosphorus removal and to assess the effect of coagulants on denitrification and organics removal by using coagulants cooperated with organisms. The result indicated that the removal efficiency of total phosphorus increased by 74.2%, and raised noticeably and meets the first class standard(GB 8978-1996) ,the average removal efficiencies of total nitrogen and organic increased by 0.04% and 8.2%. It was verified that the PAS together with activated sludge have the synergistic effect on nitrogen and phosphorus removal and the organic compound removal.
