| 摘 要： | 以静态试验的方式,研究了硫酸盐还原菌(SRB)处理不同浓度的重金属铬离子废水,以及研究了对不同浓度铬离子废水处理不同时间后的各自处理效率,从而得到处理效率最佳的初始铬离子浓度和处理时间。结果表明:当铬(Ⅵ)离子废水初始浓度为50 mg/L到100 mg/L时,SRB菌对铬(Ⅵ)离子废水的处理效率最好,达到99.62%和99.74%;并且较为经济的最佳处理时间为1 h。

| Abstract: | By using the static test the paper researched the sulfate-reducing bacteria to treat the different concentrations of ions chromium waste-water and the processing efficiency for different concentrations by treating different time,therefor to obtain the best processing efficiency with the initial chromium ion concentration and processing time.Research results indicated that when the concentration of chromium waste water is 50mg/L to 100mg/L,the processing efficiency is the best and can reach 99.62% and 99.74%;the best economical deal time is 1 h. |
