摘要
通过优化超声波功率、溶液pH、氧化剂种类和浓度、反应时间和温度等影响有机废水降解效率的因素,确定最佳预处理条件为:超声功率为150 W,pH为6,加入1%的H2O2,预处理反应时间为25 min,反应温度为50℃,COD总去除率稳定在89%左右,其他污染物去除率稳定在80%以上.
Abstract
By optimizing the factors that affect the degradation efficiency of organic wastewater,such as ultrasound power,solution pH,oxidant type and concentration,reaction time and temperature,the optimal pre-treatment conditions were determined as follows:ultrasound power was 150 W,pH was 6,1%H2O2 was added,pre-treatment reaction time was 25 min,reaction temperature was 50℃.Under above conditions,COD removal rate was stable at around 89%,and other pollutants removal rate was stable at over 80%.
