摘要
比较目前国内外对NH3 N、NO-3 N废水的各种治理技术的优缺点后 ,提出采用多流通旋转分配阀的连续离子交换分离法是治理回收高浓度、小水量NH3 N、NO-3 N废水的较适宜技术。通过实验室动态模拟试验表明 ,连续离子交换分离法不但能有效治理含NH3 N、NO-3 N的硝铵废水使废水达标排放 ,而且还能回收、提浓再生的硝铵产品返回硝铵生产工艺而产生经济效益。
Compares the advantages and disadvantages of various NH 3 N and NO - 3 N waste water treatment techniques at home and abroad,indicates that the continuous ion exchange separation using multipass rotary partition valve is a proper technique for the treatment of the small amount of waste water with high concentration of NH 3 N and NO - 3 N.The lab dynamic simulation tests show that this separation method can not only treat NH 4NO 3 waste water with NH 3 N and NO - 3 N effectively to make the waste water reach pollution exhaust criteria,but also it can recover and concentrate the regenerated NH 4NO 3,and recycle it to NH 4NO 3 production process,thus result in economic benefit.
