RESEARCH ON PROMOTION OF SELENIUM REDUCTION BY DENITRIFYING BACTERIA IN WASTEWATER AND ITS APPLICATION EXPLORATION

  • 摘要: 生物还原法处理水体硒污染,绿色经济。但大多数硒酸盐还原模式菌环境适应性较差,工程应用困难。采用某些具有硒酸盐还原能力的反硝化菌治理硒污染,则是一种新的尝试。以反硝化菌主导的硒酸盐还原菌群为研究对象,通过底物还原速率对比分析,结合微生物群落数据和功能基因定量,证实了Nap型硝酸盐还原酶主导了硒酸盐还原过程,明确了反硝化菌在还原硒酸盐过程中的作用,进一步拓展了硒还原菌谱。并以此为基础,提出了一种全新的硒酸盐污染治理策略:采用硝酸盐对活性污泥进行预驯化,可大大提升硒酸盐还原效率,因而具有一定的工程应用价值。
