摘要
对高浓度豆制品废水的预处理方法作了实验研究。采用调节等电点酸沉降的方法回收蛋白质,然后用聚合硫酸铁化学混凝处理上清液以降低COD的含量。实验证明了方法的可行性并得出了最佳实验条件。
This paper primarily discusses the pre - treatment methods of high - concentration wastewater from bean products.First of all,the protein is recovered by acid setding,then with using poly - ferric sulfate (PFS) the supernatant liquor is treated by chemical coagulation to reduce the quantity of COD in wastewater.The results show the feasibility of this method and the optimal operating conditions.
