【摘要】 利用TiO₂复合吸附剂进行了氯消毒副产物（以三氯甲烷为例）的去除实验,并与活性炭吸附法进行了对比,考察了吸附时间、吸附剂用量、溶液pH值等因素对实验的影响,结果表明,对于三氯甲烷的质量浓度为100μg/L的水样,经TiO₂复合吸附剂在一定条件下吸附处理后,绝对浓度小于10μg/L,三氯甲烷的去除率达98%,高于或相当于颗粒活性炭吸附法。本文同时对TiO₂复合吸附剂的吸附机理进行了初步探讨。更多还原

【Abstract】 The experimental study uses a titania compound adsorbent to remove the CHCl₂ in water,which is compared with using the active carbon adsorbent and focused on the effect of absorbing time,the quantity of the absorbent and the pH of the fluids.The results show that if the content of the CHCl₂ in water is 100ug/L with the treatment of the titania compound adsorbent,the absolute concentration will be below 10ug/L and the removal rate of CHCl₃ will reach 98%,which is equal to or obviously higher than using active carbon adsorbent.The effluent quality meets National Discharge Standard. This study also preliminarily examines the absorbing mechanism.更多还原
