The development history of China′s aluminum-and-iron salt industry in coagulant application including the production technology and processes of some key coagulants（polymeric ferric sulfate,polymeric ferric chloride,polymeric aluminum chloride and aluminum sulfate）,such as aluminum ash method,calcium aluminate method,aluminum hydroxide acid method,air/oxygen oxidation method and so on,in past 60 years was introduced.The development history and current status of coagulants using in China′s water treatment factory and enterprise were also reviewed.Finally,an outlook on the future trends of the aluminum and iron salt industry was presented：the theory of coagulation needs to be further developed,the development of new composite coagulant needs to be applied into practical production,and there is a misunderstanding should be awared,that is“the higher the purity,the better the effect”.
