摘要
利用淋滤反应器对破碎后的城市生活垃圾(MSW)进行处理,通过控制反应器内部温度分别在25、35、45℃条件下,对淋滤液指标及固相减量化效果进行试验研究。结果表明,随着温度的提高,淋滤液COD、VFA以及VS/TS值均不断提高,pH值不断降低。分析3种温度条件的变化趋势发现,温度从25℃上升到35℃过程中,淋滤液COD、VFA、TS和VS/TS值上升较明显,而温度从35℃上升到45℃时这种变化趋势减缓。对淋滤固相减量研究发现,35℃条件下减量效果较好,此时垃圾湿质量减量率为51. 40%、TS减量率为27. 10%、VS减量率为30. 65%。
A biological hydrolysis reactor was used to treat the shredded municipal solid waste （MSW）. The characteristics of the leachate and the MSW reduction rate were studied by controlling the temperature inside the reactor. The temperature was tested at 25℃, 35℃ and 45℃. The results showed that, COD, VFA, and VS/TS of the leachate increased and pH decreased with the increase of temperature. The analysis of the indicators under three temperature conditions revealed that, COD, VFA, TS and VS/TS increased significantly from 25℃ to 35℃, and moderately from 35℃ to 45℃. The reduction rate of dewatered solid peaked at 35℃, under which the reduction rate of wet weight, TS, and VS were 51.40%, 27.10%, and 30.65%, respectively.
