Polythiocarbonate-containing wastewater treatment agent, application thereof and wastewater treatment method

The invention relates to the field of wastewater treatment, and discloses a polythiocarbonate-containing wastewater treatment agent, an application thereof and a wastewater treatment method, the heavy metal wastewater treatment agent contains polythiocarbonate, water-soluble chitosan and/or derivatives thereof and a trimercaptotriazine compound; wherein the weight ratio of the polythiocarbonate to the water-soluble chitosan and/or the derivative thereof to the trimercaptotriazine compound is 1: (0.6-3): (0.8-3). The polythiocarbonate, the water-soluble chitosan and/or the derivative thereof and the trimercaptotriazine compound are matched for use, so that the treatment requirement of heavy metal wastewater is met, and a better precipitation separation effect is achieved when the polythiocarbonate, the water-soluble chitosan and/or the derivative thereof and the trimercaptotriazine compound are used in the wastewater treatment process. 本发明涉及废水处理领域，公开了一种含多硫代碳酸盐的废水处理剂及其应用和废水处理方法，该重金属废水处理剂含有多硫代碳酸盐、水溶性壳聚糖和/或其衍生物以及
