含硫酸盐有机废水对两相UASB反应器影响因素

Effect of Sulfate-Carrying Organic Wastewater On Two-Phase UASB Reactor

研究 SO2 -4 / COD值、水力停留时间、COD值等因素对两相 UASB反应器的日产气量、单位产气量、甲烷体积分数、COD去除率、相对产甲烷率等方面的影响 .实验结果表明 ,酸化相对上述因素的变化比较敏感 ,产甲烷相则非常稳定 .此外 ,细菌本身的特性对反应器的正常运行有重要影响 .

Regarding the effect of sulfate carrying organic waster water on two phase UASB reactor,a study is devoted to the effects of SO 2- 4/COD value,hydraulic retention time,COD on gas production,gas production rate,methane content,COD removal rate and relative rate of methane production of two phase UASB reactor.As shown by experimental results,the phase of acidification is fairly sensitive to the changes of above mentioned factors while the phase of methane production is quite stable.The property of bactercia themselves exerts important influence over the normal operation of reactor
