有机高分子絮凝剂PDMDAAC对活性染料印染废水混凝脱色研究

STUDY ON DECOLOURIZATION OF ACTIVETED DYEING WASTEWATER BY ORGANIC FLOCCULANT-PDMDAAC

用聚合氯化铝(PAC)、硫酸亚铁、PAC和聚丙烯酰胺(PAM)、PAC和聚二甲基二烯丙基氯化铵(PDMDAAC)对以活性染料为主要成分的印染废水进行混凝脱色试验,PAC+聚二甲基二烯丙基氯化铵(PDMDAAC)对印染废水的处理效果略低于PAC+聚丙烯酰胺(PAM),但PDMDAAC无毒。对脱色影响因素和控制条件等进行了试验研究。

A decolourization test for wastewater containing reactive dye has been carried out by chemical coagulation with polyaluminum chloride （PAC）, ferrous sulfate （FeSO4 · 7H2O）, PAC and PAM. PAC and PDMDAAC. The efficiency of PAC and PAM for color removal of waste water is greater than PAC and PDMDAAC but PDMDAAC is nontoxic. The influencing factors on decolourization are determined.
