pH value is one of the most important factors which affect the nitrogen and phosphorus removal in the wastewater treatment process. The influences of potential of hydrogen on nitrogen and phosphorus removal of wastewater were studied in this study. The results revealed that: (1) faintly acidic environment was conducive to biological phosphorus removal in biochemical reactors with FeCl3, PFS and PAS but not with Al2(SO4)3.On the other hand, synergistic effect between the microorganism and coagulants ( FeCl3, PFS, Al2(SO4)3 and PAS) was confirmed in this study. (2) faintly acidic environment was favorable to the nitrogen removal in biochemical reactors with PFS and PAS while the faintly alkaline environment was conducive to the nitrogen removal with FeCl3 and Al2(SO4)3. And there was no synergistic effect between the microorganism and coagulants.

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.
