ANAEROBIC SULPHATE-REDUCING MICROBIAL PROCESS USING UASB REACTOR FOR HEAVY METALS DECONTAMINATION

摘要

This study was conducted to investigate the possibility of using sewage as an organic substrate for the growth of sulphate- reducing bacteria (SRB) and to acclimatise anaerobic sludge to produce sulphide from sulphate reduction, with a view to metal precipitation. The experiments were carried out in a continuous bench-scale bioreactor (13 1 UASB reactor operated with hydraulic retention times (HRT) of 11 and 19 hours.
