无机絮凝剂除磷机理综述（英文）

论文简介：

This paper reviews the use of pre-polymerised inorganic coagulants in water and waste-water treatment, and discusses the removal
of phosphorus by chemical precipitation and coagulation. Commonly used inorganic coagulants are aluminium or iron (III) based
salts, but a range of hydrolysed Al/Fe species, and not the Al/Fe salt itself, are responsible for the removal of impurities from water.
By the development and use of polymeric inorganic coagulants, the coagulation performance can be improved significantly in
some cases. Chemical precipitation and coagulation in phosphorus removal are two different processes, with the former related to
the compound solubility and the latter depending on the destabilisation-adsorption mechanism. Presently, there is uncertainty
concerning the mechanisms and overall performance of phosphorus removal by pre-polymerised metal coagulants.
