Abstract :
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 = 30 min. The best removal efficiency of phosphate and ammonium-nitrogen all has impact on removal efficiency of phosphate and ammonium-nitrogen.
