金属前处理废水回用技术分析

Analysis of Wastewater Reuse Technology for Metal Pretreatment

金属行业废水相对其他行业更容易治理,最终实现达标排放。当前,新会区潭江、龙潭、龙溪等流域水环境容量趋于饱和,传统污水处理技术不能满足环保要求。因此,本文分析了前处理废水治理工艺,提出废水回用技术,确保前处理废水回用生产,不外排。

Metal industry wastewater is easier to manage than other industries, and ultimately achieves standards. At present, the water environment capacity of the rivers such as Tanjiang, Longtan and Longxi in Xinhui District tends to be saturated, and traditional sewage treatment technologies cannot meet environmental protection requirements. Therefore, this paper analyzes the pretreatment wastewater treatment process, proposes wastewater reuse technology, and ensures that the pretreatment wastewater is recycled and not discharged.
