摘要：

Mesophilic batch tests of cow paunch manure were carried out to obtain the ultimate biodegradability and the first-order reaction rate. Each 5 litre batch reactor was operated for 49-63 days at various substrate to inoculum ratios (LR), ranging from 0.2 to 10, without adding any chemicals. The results showed that the ultimate biodegradability of 75-83% was obtained at most LR. The first-order decay coefficient ranged from 0.044 to 0.064 day-1 for reactors operated at the LR up to 5.0. This reaction rate was faster than that found in plant biomass (e.g. sorghum, napier grass) batch tests. Accordingly the optimum ratio of cow paunch manure to inoculum, up to 2.5, was recommended for the fast start-up of a full-scale paunch manure anaerobic digester.
