中文摘要	Sulfate removal is the focal point for reutilization of sulfate-rich coal mine water. A dead-end bundle hollow fiber membrane bioreactor was developed to supply H/sub 2/ in a way similar to bubbleless aeration to resolve the electron donor deficiency which restricted biological sulfate reduction. The long-term performance of the sulfate reduction reactor at high salinity levels was evaluated for various buffering systems. The maximum sulfate reduction rate was 1.32 g/ (L ldr d) during continuous operation, 1.5 - 2.3 times higher than with other researchers. Sulfate-reducing bacteria favored alkalescent environment at high salinity levels. The optimum pH and salinity were closely related. The alkalescent reactor environment reduces the unionized H/sub 2/S concentration to alleviate the inhibitive effect of H/sub 2/S.
