摘要：

Acetate and propionate removals exceeded 80-90% in UASB reactors treating sulphate rich substrates at 37-degrees-C. The elevation of the temperature of the UASB reactors to 55-degrees-C by increments of 1-3-degrees-Cd-1 resulted in the complete cessation of propionate and sulphate conversion at 48-degrees-C, and of acetate conversion at 51-53-degrees-C, respectively. The applied fast (2-4 hours) temperature increase immediately stopped all treatment efficiencies. At 55-degrees-C, the presence of high sulphate concentration stimulated the propionate removal recovery. The UASB studies and batch assays showed that acetate was converted by methane production at 37-degrees-C and by sulphate reduction at 55-degrees-C.
