摘 要:采用臭氧氧化/脫硫水處理劑組合工藝預處理硫雙滅多威廢水,探討了臭氧投加量、脫硫水處理劑投加量、絮凝反應時(shí)間、復合堿投加量等對COD的去除率和除硫效果的影響。優(yōu)化條件為,當臭氧投加量為20 g/m3,脫硫劑投加量為50 g/L,絮凝反應時(shí)間為4 h,復合堿投加量為8 g時(shí),COD的去除率達74.8%,B/C比提高至0.43,廢水可生化性大幅提高。

Abstract: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/m3, 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.
Key words:ozone oxidation; desulfurization water treatment agent; thiodicarb wastewater; pretreatment
