微电解-水解-好氧工艺处理硝基苯废水

TREATMENT OF NITROBENZENE WASTEWATER BY THE TECHNOLOGY OF MICROELECTROLYSIS - HYDROLYZE-AEROBIC OXIDATION

采用微电解水解好氧工艺进行了硝基苯废水 (COD为 1 2 0 0～ 1 60 0 mg· L-1,色度为 3 0 0～ 40 0倍 )处理的试验研究 ,结果表明 :该工艺可有效地去除硝基苯废水中的有机物和色度 ,COD和色度的总去除率分别达到 90 % ,85 %以上 ,出水水质符合《污水综合排放标准 (GB 89781 996)》中二级标准的排放要求 .

A test is made on the technology of microelectrolysishydrolyzeaerobic oxidation treating nitrobenzene wastewater (COD=1 200～1 600 mg·L -1 , color=300～400 times). The result shows that this technology could remove the organic matter and the color contained in nitrobenzene wastewater effectively, and the removal efficiency of COD and color is above 90% and 85%, respectively. The outflow quality is accordant to the second standard of 'The Comprehensive Wastewater Emission Standard (GB 89781996)'.
