摘要
介绍了声化学氧化反应机理。采用声化学氧化法作预处理，可使生物难降解的靛兰染料废水的ＢＯＤ＿５／ＣＯＤ由０．２１—０．２３提高到０．４４—０．５１，再经间歇式活性污泥法处理后，各项水质指标均符合ＧＢ８９７８—８８《污水综合排放标准》。
In this paper,the mechanism of sonochemical oxidation, reaction is introduced. As a pretreatment method, sonochemical oxidation can increase the ratio of BOD_5/COD of the biologically refractory wastewater from indigo dye production from 0. 21-0. 23 to 0.440. 51. The pretreated wastewater is then treated by a sequencing batch reactor(SBR) activated sludge process.All water quality indicators of the final effluent can meet the national discharge standards.
