摘要
硫酸盐还原和产甲烷分别在两相UASB反应器中进行：硫酸盐还原主要在一相UASB中完成，SO4^2-去除率在85％以上；产甲烷主要在二相UASB中完成，沼气产率为0．11～0．13IMgCOD．当二相UASB中COD负荷提高到30kg／（m^3·d）时，COD去除率达到65％-77％，出水COD浓度也会明显提高．碱度不足会影响SBR的硝化效果，当补充碱度后，出水氨氮多在10mg／L以下．
Sulphate reduction is mainly in one-phase UASB,and SO4^2- removal efficiency is generally over 85%. Methane fermentation is mainly in two-phase UASB,methane reforming efficiency is 0. 11 -0. 13 L/g COD. When two-phase UASB COD loading is raised to 30 kgCOD/（ m^3 ·d） ,COD removal efficiency is from 65% to 77%, but COD concentration in drainage is better. Alkaline insufficience influences the nitration of SBR. After replenishing alkaline, ammonia nitrogen in drainage is under 10 mg/L.
