摘要：

采用膨润土吸附-微波催化氧化技术处理番茄酱生产废水,考察了膨润土添加量、H₂O₂用量、辐射时间以及微波功率对废水处理效果的影响.确定微波催化氧化的条件是:微波功率650W、辐射时间13 min、H₂O₂用量0.21mL、膨润土用量1.1g/L.在此条件下对废水进行处理,处理时间由2 h缩短为13 min,废水的COD和TOC去除率分别为88%和80.1%.

Abstract：

Microwave catalytic oxidation combined with bentonite absorption was studied for treating wastewater from tomato paste processing. The effects of microwave power,irradiation time,H₂O₂ and bentonite dosage on the degradation were examined. The best treatment conditions were microwave power 650 W,irradiation time 13 min,H₂O₂ dosage 0.21 mL and bentonite dosage 1.1 g/ L, respectively. The degradation rates of COD and TOC were 84.8% and 80.1%,respectively.
