摘　　要：采用臭氧氧化法对生化处理后的垃圾渗滤液进行深度处理,考察了反应时间、臭氧投加速率、p H和温度对COD、蛋白质、色度以及生化尾水中的腐殖酸的去除效果,通过BOD/COD变化分析了臭氧氧化法对生化尾水可生化性的提高作用。结果表明:在p H 5.0,温度35℃,臭氧投加速率9.33 mg/(L·min),反应120 min的条件下,垃圾渗滤液的生化尾水中的COD、蛋白质、色度以及腐殖酸的去除率分别达到56.2%、90.5%、97.5%和93.0%,BOD/COD从0.32提升到0.56,生化性有了很大提高。Ozone oxidation is employed to conduct advanced treatment for landfill leachate rejected from biochemical process and the effects of reaction time,dosing rate of ozone,p H and temperature on removals of COD,protein,polysaccharide,color and humic substances are investigated. Moreover,the changes of BOD / COD are studied to analyze the biodegradability of the tailwater. The results show that,in conditions of p H value 5. 0,temperature 35℃,Ozone dose rate 9. 33 mg /（ L·min）,reaction time 120 min,the removal efficiencies of COD,protein,color and humic substances can reach 56. 2%,90. 5%,97. 5% and 93. 0% respectively. The ratio of BOD / COD increases from 0.32 to 0. 56 and the biodegradability of landfill leachate is largely improved.
