Effects of Anaerobic Fermentation Temperature on Extermination of Fecal Coliform in Biogas Effluent
摘要
Abstract
Elimination of fecal coliforms in biogas effluent under either middle or high anaerobic fermentation temperature was studied to investigate whether the biogas effluent can be used to flush animal houses .After 28 d of anaerobic fermen-tation under 35°C, 99.1% of fecal coliforms in the raw swine manure , of which TS was 8%, were eliminated.Howev-er , the residual fecal coliforms concentration in the biogas effluent was still very high and cannot be used to flush the ani -mal houses.Under the high temperature of 45°C or 55°C, almost all of the fecal coliforms in the biogas effluents , dis-charged from the anaerobic fermentation of swine manure , was eliminated .The results showed that the biogas effluent dis-charged from the anaerobic fermentation under middle temperature still have high concentration of fecal coliforms .A short term treatment of anaerobic fermentation under high temperature should be applied to further eliminate the fecal coliforms in the biogas effluents and made it qualified to be used to flush the animal houses .关键词
