摘要：

通过对硫酸盐还原菌与产甲烷菌的竞争机制、硫酸盐还原产物的影响以及反应器运行性能等方面的研究,认为厌氧复合床反应器处理高硫酸盐有机废水是可行的。当进水硫酸盐质量浓度为1000～1600mg/L时,即SO₄^2-容积负荷为1～1.6kg/(m3·d)时,出水硫酸盐质量浓度为140mg/L左右,平均去除率为88.6%。

Abstract:

After the study on the competition mechanismof sulfate reducing bacteri a(SRB) and methanogens(MPB), the impact of reducing product of sulfate and the operational performance of reactor,etc.,combined anaerobic reactor is considered feasible for treating organic wastewater containing highly concentrated sulfate.When the influent SO^2-₄ is 1 000-1 600 mg/L, i. e. volumetric loading rate is 1-1.6 kg/(m3·d),effluent SO₄ 2-maintains 140 mg/L,and the average removal rate is 88.6%.

Key words: combined anaerobic reactor, organic wastewater containing highly concentrated sulfate, sulfatereducing bacteria, methanogen
