Zusammenfassung:The invention relates to the field of wastewater treatment, and discloses a metal sulfide-containing wastewater treatment agent and a wastewater treatment method, the wastewater treatment agent contains polythiocarbonate, a metal sulfide and lignin and/or derivatives thereof, and the weight ratio of the polythiocarbonate to the metal sulfide to lignin and/or derivatives thereof is 1:(0.5-4):(1-4). When the metal sulfide-containing wastewater treatment agent provided by the invention is used for treating heavy metal wastewater, not only is the treatment requirement of the heavy metal wastewater met, but also a better precipitation separation effect is achieved. 本发明涉及废水处理领域,公开了一种含金属硫化物的废水处理剂和一种废水处理方法,所述废水处理剂中含有多硫代碳酸盐、金属硫化物以及木质素和/或其衍生物,多硫代碳酸盐、金属硫化物、木质素和/或其衍生物的重量比为1:(0.5-4):(1-4)。采用本发明提供的含金属硫化物的废水处理剂进行重金属废水的处理,不仅满足了重金属废水的处理要求且具有更好的沉淀分离效果。
