摘要
在稠油炼制污水处理过程中对污水进行菌群分析,其中含有本源菌群腐生菌、铁细菌、硫细菌、反硝化菌、硫酸盐还原菌。通过对微生物菌群生长数据的分析,明确了本源反硝化菌与硫酸盐还原菌群之间的相互影响和竞争关系,揭示了反硝化菌抑制硫酸盐还原菌生长的规律。
the original microorganism flora in wastewater was analyzed during treatment of wastewater from oil refining,in which there are saprophytic bacteria、iron bacteria、thiobacteria、denitrifying bacterium、sulfate reducing bacteria.Through analysis on the growing data of microbial flora,the relation of mutual influence and competition between denitrifying bacterium and sulfate reducing bacteria was clarified,and the inhibiting rule of denitrifying bacterium to the growth of sulfate reducing bacteria.
