固定希瓦氏菌生物活性炭处理模拟染料废水研究

Shewanella sp. Strain's Fixing on Activated Carbon Against the Simulated Dye Wastewater

分离得到1株对染料活性艳红X-3B具有高效降解作用的菌株,经生理生化鉴定结合16S r DNA分析鉴定为希瓦氏菌属,命名为Shewanella sp.3Y。将该菌固定到活性炭上构建了生物活性炭小试装置,用其处理染料活性艳红X-3B及与其结构类似的7种活性染料模拟废水时,水力停留时间2 h,对模拟染料废水COD去除率均在90%以上,对色度去除率在70%以上,大部分达到90%以上,而对UV_(254)的去除率差异较大。

A strain which could degradated reactive brilliant red X-3B efficiently was screened and identified as Shewanella sp. by Vitek-32 Bacterial identification system and 16S rDNA analysis, was named Shewanella sp. 3Y. The strain was fixed on the activated carbon, and the effect of the resulting biological activated carbon colomn against several simulated dye wastewater were studied. Over 90% of COD,70% chroma （over 90% mostly） were removed in 2 h, and the removement effi-cient of UV254 had nothing in common with each other.
