摘　　要：在CSTR系统下采用逐渐提高有机负荷的半连续进料方式,研究中温(35℃)条件下渗滤液与菜场生物质垃圾混合厌氧消化的规律和性能。研究表明,试验在有机负荷条件下,以垃圾填埋场渗滤液为培养液的CSTR厌氧消化系统能顺利的进入甲烷化阶段,两种不同物料填料下,甲烷产率均稳定。当有机负荷提升到1.25 gVS·L-1d-1时,系统出现了最大日产气量、最大日产甲烷量和最大单位产甲烷率,其中以菜场生物质垃圾为物料的VS分别为6.25 L·g-1,4.58 L·g-1和0.62 L·g-1;以菜场生物质垃圾与渗滤液按7∶3比例混合填料的VS分别为6.10L·g-1,4.15 L·g-1和0.67 L·g-1。1.25 gVS·L-1d-1有机负荷时,产气性能更佳。This paper presented the regularity and performances of anaerobic co-digestion of leaehate and the biomass waste from vegetable market under condition of 35℃ and semi-continuous loading in CSTR systems. The result showed that the leaehate as the culture solution for the CSTR systems could make the system transit to methanogenic stage smoothly. When the organic loading rate reached to 1.25 gVS·L^-1 d^ -1, the maximum daily gas production, methane production and the methane production rate appeared, which were respectively 6.25 L, 4.58 L and 0.62 Lg^-1VS for vegetable waste, and 6. 10 L, 4.15 L and 0.67 Lg^-1Vs for vegetable waste mixed with leaehate at the ratio of 7： 3. And so the organic loading rate of 1.25 gVS ·L^-1 d^- 1 had the best performance.
