摘要
采用硫酸盐还原菌处理含铬(Ⅵ)废水,研究了其去除铬(Ⅵ)的最适宜工艺条件。实验表明,该菌的适用范围广,处理含铬废水的能力强。在菌液与废液体积比为1.0:1、铬(Ⅵ)质量浓度为150mg/L条件下处理36h,铬(Ⅵ)去除率达99.9%。
Sulfate -reducing bacteria (SRB) was used in the treatment of wastewater containing Hexavalent chromium. The optimum process conditions were explored. The experimental results show that SRB have strong capacity of reducing Hexavalent chromium and can be used widely. When the volume ratio of bacteria to wastewater is 1.0 :1 ,and the influent concentration is 150 mg/L,the removal rate of Hexavalent chromium is 99.9% after 36 hours of treatment.
