Abstract

Abstract:

The magnetic activated carbon(CuFe₂O₄/AC, MACC) activated S₂O₈^2- has been used for the advanced treatment of biochemical effluent of coking wastewater, and the influence of m(CuFe₂O₄):m(AC), MACC dosage, K₂S₂O₈ concentration, and solution pH on the removing effects of TOC and chroma from the biochemical effluent of coking wastewater investigated. The CCD experimental design of response surface method has been used for the optimization of reaction conditions. The results show that the optimal reaction conditions are as follows 1.5-MACC mass concentration is 5 g/L, K₂S₂O₈ mass concentration 6 g/L, and initial pH 8.3. After reacted for 360 min under these conditions, the removing rates of TOC and chroma are 85.4% and 95.2%, respectively. The result of response surface method shows that the TOC removing rate under optimal conditions is close to the model prediction value.

摘要：

采用磁性活性炭（CuFe₂O₄/AC，MACC）活化S₂O₈^2-深度处理焦化废水生化出水，考察了m（CuFe₂O₄）:m（AC）、MACC投加量、K₂S₂O₈初始质量浓度以及溶液pH对焦化废水生化出水中TOC和色度去除效果的影响，并采用响应面法中的CCD实验设计对反应条件进行优化。结果表明：最佳反应条件为1.5-MACC投加量为5 g/L，K₂S₂O₈初始质量浓度为6 g/L和初始pH为8.3，在此条件下反应360 min后，TOC、色度去除率分别为85.4%、95.2%。响应面分析结果表明，最佳条件下的TOC去除率与模型预测值接近。
