无机聚磷酸盐的应用进展

Application Development of Inorganic Polyphosphate

无机聚磷酸盐是线性聚合物,一般包括几个到几百个正磷酸盐残基,由键能较大的磷酸苷键连接而成。综述了无机聚磷酸盐在工业、农业和环保等领域的应用进展,如作为肥料、阻燃剂、食品添加剂、水处理剂等,并介绍了控制水体富营养化的强化生物除磷(EBPR)方法。

Inorganic polyphosphate（PolyP） are linear polymers containing a few to several hundreds of or- thophosphate residues linked by energy-rich phosphoanhydride bonds. The application development of Polyp in agriculture,industry and environmental protection, such as acting as fertilizer, flame retardant, food additive and water treatment agent,are reviewed. And enhanced biological phosphorus removal（EBPR） based on Polyp accu- mulation by sludge bacteria,as an accepted and low-cost strategy for controlling eutrophication is introduced.
