摘要
针对包头地区稀土冶炼工艺产生的氨氮废水,通过化学沉淀法对其进行初步处理,通过单因素实验选取最佳控制点,继而通过正交实验进行优化设计,做到用药最少,效果最好。
This article choose peculiar method on ammonia waster water that smelting craft forms of Baotou.This article analyse the content of ammonia in the waste water of smelting rare earth,and putting forward the eliminable method of the ammonia in the waste water of smelting rare earth.This experiment adopts the method of distilling the titration of chemistry precipitate to examine the content of ammonia,which does preliminary treatment on high density waste water through chemical sediment.
