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。
A pilot study was conducted on the change of temperature (fermentation temperature) with time and temperature of an anaerobic continuous digestion tank at ambient temperature and its effect on the operation performance of the digester. The results show that the anaerobic digester pool temperature buffer for changes in temperature and high relative stability; when the reactor steady-state operation, the pool temperature changes on the removal of organic matter and biogas production were more significant The relationship equations are: r (COD removal rate,%) = 0.590 3t + 81.6 6 7 and w (matrix methane yield, m3 · kgCOD-1) = 0.060 2t + 0.4 4 89.
