絮凝法处理酒精废液的研究

Treatment of Thin Stillage with Flocculation

用絮凝法处理离心分离后的酒精废液 ,悬浮物除去率为86.57%～89.62% ,COD除去率为58.2 %～59.2%。在几种絮凝剂中 ,PAC絮凝法效果较好 ,且成本低廉。

Treating the thin stillage of centrifugalization with flocculation,the removing rates of suspended solids could be 86.57%～89.62%, and the removing rates of COD could be 58.2%～59.2%.In the several flocculating agents,polyaluminium chloride(PAC)was the best one both on effects and on cost.This flocculation method is suitable for real production.
