电镀园区重金属总镍污水达标排放——以无锡杨市金属表面处理工业园为例

Electroplating park heavy metal total nickel wastewater discharge standards——Take Wuxiyangshi metal surface treatment industrial park as an example

作为国内最早进行行业整顿、环境整治的电镀集中工业园,近十年来,对园区电镀污水处理厂、入园企业以及排污管网进行了全面升级改造,取得了明显成效,但总镍排放仍难以达标。针对这一情况,笔者利用社会实践机会,到该园区专门调研,对污水总镍处理工艺技术从理论到实际作了分析比较,在此提出几点个人见解。

As one of the earliest electroplating rectifcation, environmental remediation industry concentrated industrial park, in the past ten years, the park sewage treatment plants, electroplating enterprises and sewage pipe network has been fully upgraded the transformation, and achieved remarkable results, but still diffcult to meet the total emissions of nickel. In view of this situation, the author makes use of the social practice opportunity to make a special investigation in the park, and ana-lyzes and compares the total nickel treatment technology from theory to practice, and puts forward some personal opinions here.
