【摘要】 采用静态实验遴选不同种硅藻土,进而研究其与常用混凝剂的最佳组合及复配比,考察其中几种复配剂在一定条件对城市污水的处理效果。实验结果表明:硅藻土和混凝剂组成的复配剂具有强化混凝作用;氯化铝、硫酸亚铁和高分子絮凝剂与硅藻土分别在1:9,1:11,和1:9的配比时制备复配剂处理生活污水的效果最佳。更多还原

【Abstract】 In this paper,domestic wastewater treatment is investigated using enhancing coagulation process with the blends of diatomite and coagulants (CDGC). Blends that consisted of the diatomites and coagulants were used to treat domestic sewage. The results indicate that the blends could enhance coagulation process and the efficiency of domestic sewage. The ratios of AlCl3 or FeSO4, and macromolecular coagulants to diatomites in blends is 1:9, 1:11, and 1:9, respectively.更多还原
