Abstract
Experimental research was established on the influence of temperature on the anaerobic degradation characteristics of highly concentrated organic wastewater when permeating the soil. A column experiment, using a column which contains sand at a depth of 50cm, was made at the temperature of 10°C, 20°C and 30°C over a 44 week period. Under the condition of 10°C, the removal rate of COD was about 3% due to the accumulation of volatile fatty acids. Under the condition of 20°C and 30°C, the generation of methane was observed and the removal rate of COD was about 90%. The removal of COD proceeded in the same way under the condition of 20°C and 30°C.
