Abstract

In this paper floculation performance for combinations of the inorganic flocculants and chitosan are studied,which is applied into food wastewater treatment.The experiments results for application show that flocculation effect of Fe2(SO4)3-chitosan Flocculant is best,when pH Value was 8,the temperature is 30℃and the stirring period is 5 min,which is prior to natural polymer flocculant chitosan.In addition,as for food wastewater treaiment,flocculation effect of Fe2(SO4)3-chitosan flocculant is better than that of Fe2(SO4)3-polyacrylamide compound flocculant.
