| 中文摘要 |
| 研究了天然膨润土对阳离子、分散、还原、中性、活性和直接等类有机染料的吸附特性,并比较了膨润土吸附-絮凝法与单纯絮凝法处理染料水溶液的脱色效果,前者比后者的脱色率可提高40%-200%.使用0.01%的膨润土加0.005%的聚合氯化铝,可使以阳离子染料为主的印染废水脱色率达94%-100%。 |
| 英文摘要 |
| The adsorptions of cationic, disperse, reducible,neutral, active and direct dyes on bentonite are studied respectively and the decolorization effects of treating dye-containing aqueous solution by using bentonite adsorption-flocculation method and only flocculation method are compered. The decoloriztion rate of the former will be 40%-200% higher than that of the latter. Using 0.01% of bentonite with 0.005% of PAC can decolorize the dye-containing wastewater by 94%-100%,where in the dye consists mainly of cationic dye. |
