| Abstract: | New composite modified bentonite was applied to the treatment of the dyeing wastewater of cationic dyes. The coagulation behavior of the flocculant was introduced. Influences of PH value, reaction temperature, reaction time, dosage of the flocculant, dyeing auxiliary, as well as inorganic salt were explicitly investigated. It shows the composite modified bentonite used in 0. 04 % removes color and COD by 99. 9 % and 93 % from the dyeing wastewater of cationic dyes, the ratio of sludge sedimentation is only 1 - 2 %. |
