Effect of Hydraulic Retention Time on Pretreatment of Sulfate-laden Wastewater for Desulfurization-denitrification Process

摘要：

In order to treat wastewater rich in sulfate and organic carbon,an anaerobic attached-growth bioreactor was set up.It was the pretreatment of desulfurization-denitrification process.At hydraulic retention time of 128h-6.2h,sulfate removal rate and sulfide generating rate took on initial increasing and subsequent decreasing.At hydraulic retention time of 7.7h-10.2h,the removals of sulfate and organic carbon,sulfide generating rate reached 95.79％,80％ and 58.82％,respectively.The results showed that the suitable hydraulic retention time in sulfate reduction stage for the pretreatment of desulfurization-denitrification process was 7.7h-10.2h.
