摘要

采用气浮提取蛋白 -UASB&SBR工艺处理淀粉废水, 工程运行表明在进水SS、COD_Cr、BOD₅分别为6.86 2mg/L、14467mg/L、8672mg/L的条件下, 出水SS、COD_Cr、BOD₅分别为 86mg/L、127mg/L、22.5mg/L, 处理水质稳定达到《污水综合排放标准》(GB8978— 1996 )二级标准 ;同时在处理过程中能够制取蛋白饲料和沼气, 具有显著的环境效益和经济效益。

Abstract

The air floatation collecting protein-UASB SBR process is adopted to treat starch wastewater. The application results show that when the SS, COD _Cr, BOD₅ of the influent are 6862 mg/L, 14467 mg/L and 8672 mg/L respectively, those of the effluent are 86 mg/L, 127 mg/L and 22.5 mg/L, which is stable and quite good to meet the requirement of the second grade of our national wastewater discharge standard. At the same time, the protein fodder and the marsh gas are made during the wastewater treatment, getting remarkable environmental and economic benefits.

Key words： starch wastewater; air floatation; upflow anaerobic sludge blanket; sequencing batch reactor
