废水的化学处理可以在不同的混凝剂、絮凝剂和沉淀剂的帮助下进行。混凝是最重要的化学处理方法之一。国内外学者对混凝技术进行了大量的研究，主要研究混凝剂的选择、影响因素的优化以及与其它处理方法的组合。本文就混凝的研究进展作一综述。许多研究人员建议使用聚合物基促凝剂。壳聚糖和辣木籽等混凝剂表现出良好的混凝性能。混凝与超滤或微滤联用改善了高有机负荷水的处理工艺。通过对混凝剂的选择，以及混凝与其它物化处理的合理组合，可以获得高效、经济、高效的污水处理方案。
Chemical treatment of wastewater can be carried out with the help of different coagulants, flocculating and precipitating agents. Coagulation is one of the most important chemical treatments. Various investigators have carried out investigation on coagulation aimed at studying selection of coagulant, optimization of affecting parameters and combinations with other treatment methods. Current review is aimed at summarizing research and studies on coagulation. Many investigators recommended use of polymer-based coagulant. Coagulants like chitosan and moringa seeds indicated good coagulation properties. Coagulation combined with ultraor microfiltration improved the treatment process of water with higher organic matter load. Selection of coagulating agent and proper combination of coagulation with other physicochemical treatment can lead to highly effective, economical and efficient solution for wastewater treatment.
