【摘要】 针对硝基苯废水难降解的特点 ,研究采用投加硝基苯废水降解菌群和“循环式电极反应固定床—兼性厌氧水解—投加粉末活性炭的活性污泥法”的高效工艺处理该废水。确定各处理单元的最佳操作参数。系统 15d的连续监测数据表明 ,CODcr、色度和硝基苯的总去除率分别达到 85 .1%、98.7%和 95 .9%以上。更多还原

【Abstract】 This paper reported that the nitrobenzene industrial wastewater can be effectively treated by "circle electrode reaction fixed bed-facultative anaerobic bacteria contact process-powdered activated carbon treatment" technology and the degradation bacterial group of nitrobenzene. The optimal parameters of each treatment unit were given. When the system continuously run for 15 days, the experimental data showed that the gross removal rates of CODcr, chromaticity color and nitrobenzene were above 85.1 %, 98.7 % and 95.9 % respectively.更多还原
