金属表面处理废水深度处理与回用技术初探

Preliminary Study on Advanced Treatment and Reuse Technology of Metal Surface Treatment Wastewater

金属表面处理废水中存在大量的有毒有害物质,其中含有大量重金属,直接排放将严重污染环境。同时随着两高司法解释的出台,降低了金属表面处理企业的环境犯罪入罪门槛,为降低重金属排放浓度,在一定程度上减少法律风险,企业实施废水深度处理与回用势在必行,本文主要对金属表面处理废水深度处理与回用技术对目前的一些方法进行阐述。

There are a lot of toxic and harmful substances in the metal surface treatment wastewater, which contains a large amount of heavy metals, which will directly pollute the environment seriously. At the same time, with the introduction of the two high judicial interpretations, the environmental crime threshold of metal surface treatment enterprises is reduced. In order to reduce the concentration of heavy metals and reduce the legal risk to a certain extent, it is imperative for enterprises to implement the wastewater treatment and reuse. This paper mainly deals with the technology of deep treatment and reuse of metal surface treatment wastewater. Some of the current methods are described.
