氨氮废水处理七大技术详解

发布日期:2019-06-19 作者: 点击:

氨氮废水的一般的形成是由于氨水和无机氨共同存在所造成的,废水中氨氮的构成主要有两种,一种是氨水形成的氨氮,一种是无机氨形成的氨氮,主要是硫酸铵,氯化铵等等。氨氮废水主要来自化工、冶金、化肥、煤气、炼焦、鞣革、味精、肉类加工和养殖等行业。排放的废水以及垃圾渗滤液等。氨氮废水对鱼类及某些生物也有毒害作用。另外,当含少量氨氮的废水回用于工业中时,对某些金属,特别是铜具有腐蚀作用,还可以促进输水管道和用水设备中微生物的繁殖,形成生物垢,堵塞管道和设备。处理氨氮废水的方法有很多,目前常见的有化学沉淀法、吹脱法、化学氧化法、生物法、膜分离法、离子交换法以及土壤灌溉等。本文对氨氮废水处理方法作一综述并对各种方法的优缺点进行分析汇总。

影响化学沉淀法处理效果的因素主要有pH值、温度、氨氮浓度以及摩尔比(n(Mg²﹢):n(NH4﹢):n(P04³-))等。文艳芬等人以氯化镁和磷酸氢二钠为沉淀剂对氨氮废水进行处理,结果表明当pH值为10,镁、氮、磷的摩尔比为1.2:1:1.2时,处理效果较好。丛培龙等人也以氯化镁和磷酸氢二钠为沉淀剂进行了研究,结果表明当pH值为9.5,镁、氮、磷的摩尔比为1.2:1:1时,处理效果较好。张文华等人对新出现的高浓度氨氮有机废水一生物质煤气废水进行研究,结果表明,MgC12+Na3PO4.12H20明显优于其他沉淀剂组合。
