危险废物多种重金属废水的预处理工艺研究

Study on Pretreatment Process of Various Heavy Metal Wastewater from Hazardous Wastes

本文阐述了一种含多种重金属废水的危险废物的预处理工艺的研究。实验研究了联合沉淀法降低废水重金属含量的最佳工艺参数,进而达到废水的生化处置指标。

This paper describes the research on the pretreatment process of hazardous waste containing a variety of heavy metal wastewater. The best process parameters of the joint precipitation method to reduce the heavy metal content of wastewater were experimentally studied, so as to achieve the biochemical disposal index of wastewater.
