摘要：
The denitrifying sulfide removal (DSR) process is a biorefinery process that can produce colloidal S from sulfide and nitrate-laden wastewaters. At long reaction time the formed S produced is reduced back to sulfide by sulfate-reducing bacteria so the resulting in poor conversion rate of S is poor. The presence of optimal hydraulic retention time (HRT) for maximizing S conversion from DSR wastewaters was proposed by batch assays and then confirmed in continuous flow tests.
