Synthesis and Application of Inorganic-Organic Hybrid Flocculant

Abstract:

A series of inorganic-organic hybrid flocculants were synthesized by using aluminum chloride, ferric chloride, polyacrylamide (neutral & cationic) and polydimethyldiallyl ammonium chloride as raw materials. Effect of mass ratio of inorganic and organic polymeric flocculant, basicity, categories of inorganic and organic polymeric flocculant on the regeneration of coking wastewater was investigated. The results showed that the optimum conditions of preparation the title hybrid flocculant were: mass ratio 100, basicity 1.5, inorganic polymeric flocculant PAFC and organic polymeric flocculant CPAM. The removals of CODCr and chroma were 43.48% and 71.88%, respectively, when the pH of raw water was approximately 7 and the dose of flocculant was 360 mg•L–1.
