摘　　要：采用水解酸化反应器与复合厌氧反应器组合工艺处理高浓度抗生素废水 ,试验结果表明 ,水解酸化反应器最大容积负荷可达 16 .84kgCOD/ (m3·d) ,有效降低了毒性物质的抑制作用 ;复合厌氧反应器最大容积负荷可达 8.5 7kgCOD/ (m3·d) ;系统进水最大SO2 - 4浓度为 132 5mg/L ,COD/SO2 - 4值最低为 3,COD与SO2 - 4的总去除率分别为 75 .5 %和 95 .2 % ,对各种抑制物质和冲击负荷表现出很好的适应性。试验证明 ,水解酸化—厌氧消化工艺可以有效消除SO2 - 4对厌氧处理的影响 。Combination process of hydrolysis acidification - hybrid anaerobic reactors was used for the antibiotic wastewater treatment. The result showed that the maximum volumetric loading rate of hydrolysis acidification reactor can be up to 16.84 kgCOD/(m 3·d), which effectively reduces the inhibition of toxic matters; the maximum volumetric loading rate of hybrid anaerobic reactor reaches 8.57 kgCOD/(m 3·d). In the influent of system, the highest concentration of SO 2- 4is 1 325 mg/L and the lowest COD /SO 2- 4 is 3, and total removal rate of COD and SO 2- 4 is 75.5% and 95.2% respectively, showing good adaptability to all inhibitory substances and shock loading. The test demonstrated that hydrolysis acidification - anaerobic digestion process can effectively eliminate the effect of SO 2- 4 on anaerobic treatment and is economically feasible to the treatment of high strength antibiotic wastewater.
