摘要
以黄浦江水源地突发污染为背景,通过实验重点研究了粉末活性炭(PAC)吸附技术对甲苯的应急处理效果,包括PAC投加量、吸附时间等因素对处理效果的影响。结果表明:针对低浓度的甲苯突发污染,强化PAC投加量,可大幅提高对其的去除率,但当突发污染倍数较高时,去除率提高幅度较小。
Emergency treatment efficiency of toluene by PAC adsorption was investigated by experiment in the background of sudden pollution occurred in Huangpu source water. Effect of PAC dosage, adsorption time on treatment efficiency was investigated. The experimental resuhs show that enhancing PAC dosage can significantly improve removal ratio of toluene on low concentration level, but have little contribution for high concentration pollution.
