| 摘 要： | 探讨粉煤灰、活性炭和膨润土等吸附剂对硫酸锰溶液中残余少量有机物的吸附效果,并以膨润土为吸附剂进行单因素试验,考察了膨润土用量、吸附时间、pH和温度对吸附效果的影响。结果表明,使用膨润土吸附剂,在溶液pH为7.0,25℃,吸附时间30min,膨润土用量10.0g的条件下,硫酸锰溶液的COD去除率可达32.4%;改性膨润土较未改性原土脱除溶液中有机物的效果更好,且酸化改性膨润土优于热化改性膨润土,COD去除率达到40.8%。

| Abstract: | The adsorption performance of coal ash,bentonite and activated carbon to removal organic residues in manganese sulfate solution was investigated.Bentonite was chosen as adsorbent for single factor experiment to examine the effects of dosage of bentonite,pH,time and temperature on adsorption.The results show that with bentonite as adsorbent,COD removing rate is 32.4% under the optimal conditions including pH value of solution of 7.0 and dosage of bentonite of 10.0 g for 30 min at 25 ℃.The removal effect on organic matter with modified bentonite is better than that of with unmodified bentonite,and the effect of acidification modified bentonite is better than that of thermalization modified bentonite.The COD removing rate of acidification modified bentonite is 40.8%. |
