工业废水中的氨氮处理

Ammonia-nitrogen Treatment in Industrial Wastewater

工业废水中的氨氮造成自然界水体的富营养化,对生态平衡带来极大威胁,因此需要研究工业废水中氨氮的去除。目前工业废水中的氨氮处理常用以下几种方法:吹脱法、化学沉淀法、折点氯化法、生物硝化反硝化法等。综述了国内氨氮废水处理的研究现状,分析几种常用方法的优劣之处,为后期研究者提供参考。

Ammonia-nitrogen in industrial wastewater causes eutrophication of natural water bodies and poses a great threat to ecological balance.At present,ammonia-nitrogen wastewater is commonly used in the following methods:ammonia blow method,chemical precipitation method,fold-point chloridize method,biology nitration method,etc.,this paper summarizes the current situation of domestic ammonia nitrogen wastewater treatment,analyzes the advantages and disadvantages of several common methods,and provides reference for later researchers.
