摘要
本文以无机絮凝剂Fe2(SO4)3与壳聚糖复配进行絮凝性能研究,并对实际食品废水进行处理。实验表明,以高岭土悬浮液为絮凝对象,当pH值为7,温度为30℃,搅拌时间为5min时,Fe2(SO4)3-壳聚糖絮凝剂的絮凝效果为最佳而且优于单独使用无机絮凝剂Fe2(SO4)3和天然高分子絮凝剂壳聚糖。以实际食品废水为絮凝对象,Fe2(SO4)3-壳聚糖的絮凝效果优于Fe2(SO4)3-聚丙烯酰胺复配絮凝剂的絮凝效果。
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 p H 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.
