摘　　要：开发了三阶段两相厌氧工艺即酸化、内电解、厌氧产甲烷的工艺处理皂素废水.从理论上分析了该工艺处理黄姜皂素废水的机理和优势.在实验条件相同时,改变内电解在工艺中的位置进行间歇式厌氧处理,测得2种厌氧工艺的处理效果.实验结果表明内电解在两相厌氧中间CODC r的去除率要优于内电解在酸化前.Because the sapogenin wastewater is high -consistency organic wastewater, we developed the two- phase anaerobic digestion with three stages that acidification phase, inner electrolysis phase and methane phase. We analyse the mechanism and advantage of the two - phase anaerobic digestion disposal the sapogenin wastewater. In the similar conditions, we shift the position of inner electrolysis in the technics to proceed the intermittent anaerobic experiment. The experimental results demonstrate that effluent remainder CODCr of two - phase anaerobic digestion with three stages is obviously lower than the technics that inner electrolysis before acidification.
