摘 要：
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.
