Progress and research of Organic Polymeric Flocculant in water treatment

摘要

coagulation and sedimentation method is an effective water treatment method, and the key factor is the choice of flocculant, according to its different chemical composition, it is generally divided into inorganic, organic, microbial flocculants. Because of the small dosage,fast flocculation and less effect by external environment, organic polymeric flocculant has widely used in wastewater treatment. This paper describes some types of organic polymer flocculation and its research and application. finally,the development trend of organic polymeric flocculant was predicted.
