摘要
对MAP法处理高氮高磷制药废水进行实验研究,探讨了反应物浓度、pH值、n(Mg):n(N)、n(N):n(P)和镁盐种类对MAP法脱氮除磷效果的影响。结果表明:当废水反应物浓度(以N计)1500mg/L,p H=9.0~9.5,n(Mg):n(N)=1.1~1.2,n(N):n(P)=0.95~1.0,反应沉淀剂为MgCl_2·6H_2O,反应温度20℃,反应时间1h时,废水中氨氮、磷酸盐去除率可分别达96.7%、99.6%。
Experimental research on treating the pharmaceutical wastewater with high concentration of nitrogen and phosphorus by magnesium ammonium phosphate（ MAP）,the concentration of reactant,p H,n（ Mg） ： n（ N） 、n（ N） ： n（ P） and species of magnesium salt on the influence of removing ammonia nitrogen and phosphate are discussed. The results show that：When the concentration of reactants in the wastewater（ in N） is 1500 mg/L,p H = 9. 0 ~ 9. 5,n（ Mg） ： n（ N） = 1. 1 ~ 1. 2,n（ N） ： n（ P） = 0. 95 ~ 1. 0,reaction precipitator is Mg Cl2·6 H2 O,reaction temperature is 20 centigrade degree,and the reaction time is 1 hour,the removal rate of ammonia nitrogen,and phosphate in the wastewater is 96. 7%,99. 6% respectively.
