铁基树脂的制备及其对水中络合重金属催化降解性能研究任务书

 2020-04-17 08:04  

1. 毕业设计(论文)的内容和要求

内容: 金属矿冶炼、电解、电镀等行业每年要排放大量含重金属离子的废水,重金属废水排放到环境中不能被微生物降解,并通过土壤、水、空气,尤其是食物链,对人类健康、动植物及水生生物产生严重危害。

近年来随着表面处理技术的发展,电镀、化学镀被广泛应用,而这种工艺中大量使用的络合剂,使重金属废水的成分更加复杂。

以电镀行业重金属废水为例:电镀废水中含有铜、镍、镉、铅、铬等有毒有害重金属离子、氰化物、乙二胺四乙酸(edta)以及表面活性剂、光亮剂、防染盐等污染物。
