Study on the Effective Technique for Nitrobenzene Industrial Wastewater Treatment |
| |
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. |
