突发性酚污染事故处理方法

Research on treatment method of sudden phenol pollution accident

摘要:

为应对日益增加的水体突发性污染事故,研究了活性炭、活性炭纤维、膨润土和粉煤灰的吸附性能及吸附时间、温度等吸附条件对活性炭吸附酚性能的影响.结果表明:活性炭最适合做应急吸附材料,吸附时间最好在60 min以上;活性炭投加量增加,去除率先迅速上升,后趋于平缓;苯酚初始质量浓度增加,去除率略有下降.当河流中发生突发性酚污染事故时,可设置活性炭拦截吸附网.

Abstract:

In response to sudden phenol pollution accidents,the adsorption performance of activated carbon,carbon fiber,bentonite and fly ash were studied,and the effects of the adsorption time and temperature conditions on activated carbon were studied too.The results indicates that the activated carbon is the most appropriate adsorption material.The adsorption time should be preferably more than 60 min.With the dosage of activated carbon increasing,the removal rate rise rapidly,and then flatten.With the phenol initial concentration increasing,the removal rate decreased slightly.When the sudden phenol pollution accidents occurred in the river,the activated carbon interception and adsorption nets should be set.
