摘　　要：水处理絮凝剂的发展经历了从最初的传统絮凝剂,到无机高分子絮凝剂,再到有机高分子絮凝剂;从简单的天然有机高分子絮凝剂,到合成的有机高分子絮凝剂,再到基于生态安全性的天然改性有机高分子絮凝剂;从单纯的无机或有机高分子絮凝剂,到有机-无机复合絮凝剂;从化学絮凝剂,再到具有生态安全性能的生物絮凝剂.为了促进水处理絮凝剂的迅速发展和实际应用,本文综述了水处理絮凝剂在国内外的研究进展与应用现状,重点对化学和微生物两大类絮凝剂分别阐述了其特点以及在水处理中的应用情况,并对其发展方向进行了分析和评价;尤其是针对目前我国絮凝剂研究与开发应用中的不足,对今后的研究工作提出了一些建议和设想.Water-treatment flocculants are being developed from traditonai to inorganic, from inorgamc to organic, from natural organic to synthetic organic, from synthetic organic to modified natural organic, from inorganic or organic to inorganic-organic, and from chemical to biological with ecological safety, In order to promote the rapid development and practical application of water-treatment flocculants, the research progress and application situation of flocculants for water treatment at home and abroad were reviewed. In particular, the characteristics of two important flocculant types, chemical and microbiological flocculants, as well as their application processes in water treat mentwere summarized, their development orientations were analyzed and evaluated, and the future research directions aimed to overcome the current shortages in developing and applying flocculants in China were put forward.
