摘要
通过单因素变量实验研究了MAP法处理氨氮废水的处理效果,分析了反应温度、pH值、反应物投放比例和氨氮浓度对氨氮去除率的影响。实验表明,温度为30℃,pH=9.5~10,n(Mg2+)∶n(PO34-)∶n(NH4+)=1∶1.2∶1时,氨氮去除率分别达到最佳;在相同条件下,一定浓度范围内,随着氨氮浓度的增加,去除效果有增加的趋势。
Through the single factor variable experimental study the MAP method on the treatment of am- monia nitrogen wastewater treatment effect. Analysis of the reaction temperature, pH value, reactant on the scale and ammonia nitrogen concentration on the influence of ammonia nitrogen removal efficiency. Exper- imental results showed that the temperature of 30 ℃, pH = 9.5 - 10, between n (Mg^2+ ): n (PO4^3-): n ( NH4 + ) = 1 : 1.2: I in ammonia nitrogen removal efficiency to achieve the best respectively;and in the same condition, the certain concentration range, with the increasing of the concentration of ammonia nitro- gen removal efficiency has a trend of increase.
