介绍了混凝工艺在饮用水除砷中研究进展，内容包括：常规混凝，强化混凝，电解-混凝和混凝-微滤。重点评价了各种混凝工艺的优缺点、应用范围及发展方向。砷一般以As（Ⅲ）与As（V）形态存在，As（Ⅲ）比As（V）更不稳定，毒性更大。常规混凝简单易行，但去除As（Ⅲ）的效果比As（V）差，通常需要进行强化混凝，电解-混凝和混凝微滤作为新的混凝技术已展现出更多的优势。混凝工艺具有低能耗、易操作、高效率等优点，应成为今后饮用水除砷技术的发展重点。

The research progress of coagulation for arsenic removal in drinking water is delineated, which is inclusive of con- ventional coagulation, enhanced coagulation, electrocoagulation, coagulation - microfihrafion process. The advantages, disadvantages and developing directions of various coagulation technologies and their applicable scope are analyzed in this paper. Generally, the existence forms of arsenic are As（ Ⅲ ） and As（ V ）. Conventional coagulation is simple and easy to handle, but not as ef- ficient for As（ Ⅲ） removal as for As（ V ） removal, and enhanced coagulation is usually added. As new coagulation technologies, electroeoagulation and coagulation - microfiltration process have shown more advantages. The process is characteristic of energy saving, easy handling and high performance, which is considered to he key technology on arsenic removal in drinking water.
