SBR处理生物质煤气废水试验研究

Study on the treatment of wastewater produced by biomass gasification power plant with sequencing batch reactor biological technique

生物质煤气废水经预处理后,运用SBR工艺对其进行处理,考察了反应温度、反应时间、pH、曝气方式等因素对SBR去除CODCr效果的影响.SBR工艺处理能有效地去除该废水的CODCr,当进水浓度CODCr为979.2～1316.7mg.L-1时,经SBR处理,出水CODCr为166.7～229.2mg.L-1,去除率达82.9%～85.4%.

Treatment of wastewater produced by biomass gasification power plant with sequencing batch reactor biological technique was described. The effects of different reaction time, reaction temperature, pH value and aeration way on treating the wastewater were studied. SBR was adopted to treat this wastewater , as inlet CODc, were 979.2-1316.7 mg·L^-1 , after treatment by SBR , the outlet CODc, decreased to 166.7-229.2 mg·L^-1 ,CODc, removed rate were 82.9-85.4%.
