摘要
采用声化学氧化法作预处理，可使生物难降解的染料废水可生化性ＢＯＤ５／ＣＯＤ值由０．２２～０．２８提高到０．４４～０．５１。再经间歇式活性污泥法（ＳＢＲ）处理后，各项水质指标均符合ＧＢ８９７８－８８《污水综合排放标准》中的一级标准。
The sonochemical oxidation is used for pretreatment, the biochemistry ability of dye stuff waste water of refractory biode gradation BOD 5/COD value could be increased from 0.22￣0.28 to 0.44￣0.51. After treating again by intermittent active sludge process(SBR), all the quality indexes of water are agree with the first order in the 《Integrated Sewage Discharge Standard 》(GB8978 88).
