However, it is a kind of natural nontoxic polymer, itself and its modified products have good flocculation performance, plays an important role in wastewater treatment. This paper mainly introduces the principle of chitosan flocculation and its application in wastewater treatment research. This paper describes the structure and properties of chitosan and chitosan LDH synthetic industry, the application of chitosan and its application in wastewater treatment research. By experiment research is mainly focused on the process of chitosan, LDH zhejiang optimal PH value of the sewage treatment ...
