甲壳素和壳聚糖在污水处理中的应用进展

Applying Chitin and Chitosan in Sewage Treatments:Practice and Progress

针对工业废水中重金属和有机质含量高、难以去除且处理成本高的现状,该文聚焦来源于海洋虾蟹壳的活性物质甲壳素及其脱乙酰基产物壳聚糖,综述其在处理城市污水与工业废水中的高效性,从高吸附性与环境安全性等方面阐述该类物质在工业废水处理中的应用;同时基于国内外最新进展并结合实验室研究成果对该类起源于海洋的活性物质在水处理中的应用前景进行展望,以期为进一步开发基于海洋的环境友好型水处理方法提供参考。

With the continuous development of human activities and industrial production,the treatment and discharge of urban sewage and industrial wastewater can not be ignored.Under the strategic guidance of the new national environmental protection policy,the development of new sewage treatment means with high treatment efficiency,low cost and no pollution is the future trend of the industry.This paper summarizes the practical application of chitin and its deacetylated product chitosan in urban sewage and industrial wastewater treatment,and comprehensively analyzes its future application prospects,so as to provide a research basis for the further development of marine environment-friendly sewage composite treatment agent.
