摘要
配位剂是影响电镀废水稳定达标的主要因素之一。指出电镀废水应考虑其中所含配位剂的性质,从源头分类收集,采用氧化、水解、化学沉淀、生物等方法预处理。电镀废水治理的重点是重金属离子,难点是配位剂,关键是分类收集。
The existence of complexing agents is one of the reasons for unsteady emission of electroplating wastewater. The wastewater streams containing different complexing agents should be segregated from their sources according to the properties of complexing agents, and then pretreated individually by oxidation, hydrolysis, chemical precipitation, biological treatment or other methods. Heavy metal ions should be focused on during the treatment of electroplating wastewater. The difficulty is the degradation of complexing agents. Separate collection is the key.
