等离子体协同改性活性炭净化邻苯二甲酸二甲酯废水

Purification of DMP Wastewater by Plasma Co-modified Activated Carbon

为了探索邻苯二甲酸二甲酯(DMP)废水高效降解方法,采用等离子体协同硫酸亚铁改性活性炭净化DMP废水。结果表明:放电电压40 kV、原液pH值6、放电时间60 min时,化学需氧量(COD)去除率为98.29%;放电电压80 kV、原液pH值2、放电时间60 min时,浊度去除率为95.00%。该结果与软件预测结果吻合度较高。

In order to explore the efficient degradation method of dimethyl phthalate(DMP)wastewater,in this paper,plasma and activated carbon modified by ferrous sulfate are used to purify DMP wastewater.The results show that the discharge voltage is 40 kV,the pH of the original solution is 6,the discharge time is 60 min,and the COD removal rate is 98.29%.The discharge voltage is 80 kV,the pH of the original solution is 2,the discharge time is 60 min,and the turbidity removal rate is 95.00%.The result is in good agreement with the software prediction.The software predicts that the discharge time is 60 min,the pH of the original solution is 2,the discharge voltage is 40 kV,the COD removal rate is 86.803%,and the turbidity removal rate is 96.743%.This study provides a new idea for DMP wastewater treatment.
