摘　　要：采用臭氧氧化/脱硫水处理剂组合工艺预处理硫双灭多威废水,探讨了臭氧投加量、脱硫水处理剂投加量、絮凝反应时间、复合碱投加量等对COD的去除率和除硫效果的影响。优化条件为,当臭氧投加量为20 g/m^(3),脱硫剂投加量为50 g/L,絮凝反应时间为4 h,复合碱投加量为8 g时,COD的去除率达74.8%,B/C比提高至0.43,废水可生化性大幅提高。An ozonation/desulfurization water treatment agent combination process was used to pretreat dipmethomyl wastewater.Factors including the dosage of ozone,desulfurized water treatment agent dosage,flocculation reaction time,dosage of compound alkali influence on COD removal rate and sulfur removal effect in this combined process.The result showed that when the dosage of ozone was 20 g/m^(3),the dosage of desulfurizer was 50 g/L,the flocculation reaction time was 4 h,the dosage of compound alkali was 8 g,the removal rate of COD is 74.8%,B/C ratio increased to 0.43,biodegradability was greatly improved.
