摘要
通过静态吸附实验,研究了黄河底泥对以氯苯为代表的氯代芳烃类有机物的吸附规律及机理,在此基础上进一步研究了絮凝剂(铝铁共聚物)对氯苯去除率的影响及机理。结果表明,黄河底泥对氯代芳烃类有机物的吸附主要通过其表面及微孔作用。加入絮凝剂后氯苯的去除率明显提高,这是由于絮体在形成过程中的凝聚、卷扫、网捕作用使水体中微小胶体颗粒得以沉降,进而增加了有机物的去除率。
Through static adsorption experiment,the adsorption behaviour and mechanism of chlorobenzene as exponent of chloroarene onto sediments in Yellow River are studied.The influence of flocculating agent for absorption and sedimentation is also studied.The results show that the adsorption of chlorobezene onto these sediments is mainly through the surface and microporosity of the particulate matter. The removal rate of chloroarene in solution is hanced when flocculating agent is added in,because the floc has coacervation and net-capture function to collidal substance in sedimentation.
