摘　　要：对一种高效连续式常温地埋厌氧消化池池温 (发酵温度 )随时间和气温的变化情况 ,及其对消化池运行性能的影响进行了中试研究。研究结果表明此类厌氧消化池池温对气温的变化缓冲能力强 ,相对稳定性高 ;当反应器稳态运行时 ,其池温的变化对有机质的去除和沼气的产生量均有较为显著的影响 ,其关系方程分别为 :r(COD去除率 ,% ) =0 .5 90 3t+ 81.6 6 7和w(基质甲烷产率 ,m3 ·kgCOD-1) =0 .0 0 6 2t+ 0 .4 4 89。Fluctuating of digestion temperature of a kind of high performance underground anaerobic digester with time and air temperature was studied. and a set of pilot experiment was taken to observe the possible affections on performance caused by the temperature fluctuating. It was found that the digestion temperature of the underground anaerobic digester was relatively stable with the air temperature's rise and drop. When the reactor is in steady state operation, there were a certain quantitative coefficients between digestion temperature and COD removal rate and the production rate of COD to CH 4, which can be expressed by the equations of r(COD removal rate,%)=0.5903t+81.667 and w(the production rate of COD to CH 4, m 3·KgCOD -1 )=0.0062t+0.4489 respectively.
