MAP法处理中浓度氨氮废水的探讨

Treatment of Medium Concentration Ammonia Nitrogen Wastewater by MAP Method

氮在水中主要是以有机氮和氨氮的形式存在的,污染受纳水体,影响水环境质量。高浓度氨氮废水可采用吹脱、汽提法去除。中、低浓度氨氮废水可采用MAP法沉氨预处理,除去大部分氨氮后,再经生物处理去除剩余的氨氮。MAP法去除中、低浓度的氨氮处理效果良好,并无二次污染。

Nitrogen in water mainly is in the form of ammonia nitrogen and organic nitrogen, which can pollute the receiving water body and affect water environment quality. High concentration ammonia nitrogen wastewater can be treated by stripping method, medium or low concentration ammonia nitrogen wastewater can be pretreated by MAP method, then the biological treatment can be used to remove residual ammonia nitrogen. MAP method has good effect to treat medium or low concentration ammonia nitrogen wastewater, and there isn＇t second pollution.
