摘要
H酸综合废水 ,成分复杂、毒性大 ,针对上述废水进行了系统的实验研究 ,结果表明 :用铁屑过滤装置处理该废水 ,提高其BOD5、CODcr比值 ,再用生化法处理 ,COD、NH3 N去除效果明显、且流程简单 ,投资省、运行费用低。
This paper is about the treatment of H-acid comprehensive waste water which is complex in ingredient and serious in poison.We did systemic experiment on this kind of waste water.The result shows that it can increase the ratio of BOD s/COD cr if we use scrap iron filtration device to treat this kind of waste water.After that,when we use biochemical method to treat it,the decrease of COD and NH 3-N is obvious.This method also has other advantages such as simple flow,small investment and low cost of running.
