碳酸盐一硫酸盐含钙矿物对啤酒废水厌氧产甲烷过程的影响
Effects of carbonate-sulfate calcium minerals on the anaerobic methanogenic process of brewery wastewater
摘要
Abstract
Adding external additives is one of the effective means for enhancing anaerobic methanogenic process.In the current study,four natural calcium-containing minerals of anhydrite,calcite,gypsum and dolomite were adopted to improve the anaerobic conversion efficiency of brewery wastewater with the interaction between minerals and microorganisms.Results indicated that the removal rate of COD reached 88％ and above in all ex perimental groups.Methane production in the minerals dosed reactor was significantly higher than the control.Minerals also influenced the fermentation and acidification process.The butyric acid type fermentation was the main fermentation process in the minerals dosed reactor.Addition of calcium-containing minerals had a signifi cant promotion effect on the anaerobic digestion process of brewery wastewater.关键词
