【摘要】 用聚二甲基二烯丙基氯化铵(PDMDAAC)改性高炉渣以提高其对印染废水的处理能力.研究了改性过程中改性剂浓度、温度和制备时间对改性效果的影响,对模拟印染废水和实际印染废水进行了处理,表明PDMDAAC改性大大提高了高炉渣对染料的吸附能力.更多还原

【Abstract】 To improve the absorbability of boiler furnace(BF)slag in treating dyeing waste water,it was modified by using PDMDAAC.The current paper deals with an investigation on the effects of preparation time,temperature and concentration of PDMDAAC on the preparation of PDMDAAC-BF slag,and the results show the best process conditions.Treatment of simulated and practical dyeing waste water had been carried out and showed PDMDAAC-BF slag had stronger absorbability in treating dyeing waste water than that without modifying.更多还原
