摘要 硫酸盐生物还原在含硫酸盐废水的处理中具有明显优势,然而富含硫酸盐的废水通常缺乏电子供体,因此电子供体的选择及添加就成了该工艺推广所面临的主要问题。本文综述了用于硫酸盐生物还原的各种电子供体,包括氢、甲酸、甲醇、乙醇、乳酸、挥发性脂肪酸、糖类、烃类和有机废物,讨论了适宜电子供体的选择标准。 Biological sulfate reduction is fit for treating sulfate-containing wastewaters.But sulfate rich wastewaters are usually deficient in electron donors.Theoretically,sulfate conversion requires electron donors,and requires external addition of electron donors in order to achieve complete sulfate reduction.In this papers,various electron donors employed in biological sulfate reduction are reviewed.Widely used electron donors include hydrogen,formate,methanol,ethanol,lactate,volatile fatty acids(VFA),sugar,hydrocarbons and organic waste.The selection criteria for suitable electron donors are discussed.
