The Experimental Research on Removal Phosphorus and Nitrogen in Supernatant of Thickener from Municipal Wastewater Treatment Plant by MAP
2009
Propose a method of MAP for the supernatant from thickener of municipal wastewater treatment plant, principal orders of factors which affect MAP precipitation process, concluded by orthogonal experiment and the Optimal Test are as following: pH value, n(Mg):n(P) and reaction time. The optimum reaction conditions are pH=9, n(Mg):n(P) =1 and t=30min. The best removal efficiency of phosphate and ammonium-nitrogenall has impact on removal efficiency of phosphate and ammonium-nitrogen.
