| 摘 要： | 用壳聚糖和粉煤灰对含间甲酚的废水进行吸附处理,考察了壳聚糖的用量、振荡时间、振荡速度以及粉煤灰与壳聚糖的混合比对处理效果的影响.结果表明:在常温下,对于初始质量浓度为56 mg/L的间甲酚,当壳聚糖用量为3 g/L,以170 r/min的转速吸附振荡0.5 h,去除率可达到88%以上;在上述条件下,加入质量比4:1的粉煤灰与壳聚糖混合物5g/L时,间甲酚的去除率可达到91%.

| Abstract: | The wastewater containing m-cresol was treated by adsorption of chitosan and coal ash. The influences of the factors such as amount of chitosan,vibrating time and velocity,and ratio of coal ash to chitosan on the treating efficiency were investigated. The results showed that the removal rate of m-cresol could achieve more than 88% when amount of chitosan was 3 g/L,vibrating time was 0.5 h and vibrating velocity was 170 r/min,and the removal rate of m-cresol could be up to 91% when coal ash was 4 g/L and chitosan was 1 g/L under normal temperature and original concentration of m-cresol 56 mg/L. |
