浅谈含重金属电镀废水的治理

Treatment of Electroplating Wastewater Containing Heavy Metal

电镀加工产生的含重金属离子废水数量大,成分复杂。重金属废水对生态环境危害极大。重金属离子富集在人体内可致癌、致畸和致染色体异常。重金属的治理已列入国家"十二五"规划。源头控制,过程阻断,末端治理达标排放是治理重金属污染有效手段;从長远考虑,应创新重金属废水的整治技术;开展清洁生产和循环经济,使电镀产生的重金属废水数量和危害最小化,最终实现回收利用的目标。

Electroplating wastewater containing heavy metal is extremely serious harmful to ecological environment due to its large quantity and complex composition. Accumulation of the heavy metal ions inside human body could cause cancer, distortion and chromosomal anomaly. Now, heavy metal pollution control has been listed in the National ＂ 12th Five-Year Plan＂. Source controlling, process blocking and discharging up to standard through end treatment are effective means of heavy metal pollution control. Take a long view of this matter, innovation of pollution control technology, cleaner production and recy- cling economy, minimization of wastewater quantity and its pollution are very important issue,in so doing, the recycling target could be achieved.
