摘　　要：针对餐厨垃圾沼液色度高和臭味刺鼻的问题,采用臭氧曝气技术对沼液进行除臭脱色处理,探究不同气水比与温度对臭氧曝气处理效果的影响。结果表明,当气水比为1∶25时,沼液臭气排放值低于70,达到农用沼液标准,臭氧单位处理沼液量最大,同时色度去除率超过90%。随着温度升高,除臭脱色效果减弱,最佳温度为25℃。该研究为餐厨垃圾沼液除臭脱色提供了可行技术。To address the issue of high-chroma and pungent odor of biogas slurry of food waste,this study used ozone aeration technology to deodorize and decolorize the biogas slurry,and explored the effects different air/water ratio and temperature on ozone aeration treatment.Results showed that when air/water ratio was 1∶25,the odor emission value of biogas slurry was lower than 70,which reached the standard of agricultural biogas slurry use,the amount of ozone unit treatment biogas slurry was the largest,and the chroma removal rate could reach more than 90%.With the increase of temperature,the deodorization and decolorization decreased,and the optimal temperature was 25℃.This study provides a feasible technology for deodorizing and decolorizing biogas slurry of food waste.
