【摘要】 以炉灰剂脱色对分散红染料废水进行脱色处理研究,结果表明,炉灰脱色剂是分散红染料废水很好的脱色剂,其脱除率可达99.84％。用炉灰脱色剂对分散红染料废水进行脱色处理,以废治废,不但炉灰价廉易得,处理设备简单,操作方便,处理时间短,对分散红废水无需进行pH值的调整。炉灰脱色剂再生后可多次重复利用,大大降低了处理成本,而且脱色效果较许多已知的方法还好。更多还原

【Abstract】 In this paper, the stove-ash was used as decolourization agents for the scatter about the red dyestuff treatment in textile.lt was proved by ours experiment that the stove-ash was a very good decolourization agents for the scatter about the red dyestuff waste water, the decolor ratio of red are 98.84% in textile. There are great advantages, when using the stove-ash as the decolourization agents.For examples, the coal-ash, itself a waste, it is very easy to obtained, the equipment for the waste water treatment is simple and easy to operate,the time used for treatment is shorter than general,the stove-ash as the decolourization agents could be regenerated and reused, it need not adjust the pH of the waste water for the treament , the cost of the treatment is low.更多还原
