【摘要】：采用UASB反應(yīng)器考察氯霉素對(duì)反硝化脫硫工藝運(yùn)行效能及微生物群落結(jié)構(gòu)的影響。結(jié)果表明,氯霉素的投加對(duì)反硝化脫硫工藝影響不大。通過高通量測序技術(shù)分析微生物群落結(jié)構(gòu),發(fā)現(xiàn)氯霉素的存在會(huì)降低反應(yīng)器中反硝化脫硫污泥微生物群落多樣性。高氯霉素條件下,Thauera、Pseudomonas和Azoarcus是主要的異養(yǎng)反硝化微生物,Sulfurovum和Thiobacillus是主要的自養(yǎng)反硝化微生物,這些微生物使系統(tǒng)保持較好的硫氮同步脫除效果,此外,胞外聚合物尤其是胞外蛋白隨氯霉素濃度增加而增加。
[Abstract]:The effects of chloramphenicol on the operation efficiency and microbial community structure of denitrification desulfurization process were investigated by UASB reactor. The results showed that the addition of chloramphenicol had little effect on denitrification desulfurization process. The microbial community structure was analyzed by high throughput sequencing technique. It was found that the existence of chloramphenicol could reduce the diversity of microbial community in denitrification and desulphurization sludge in the reactor. Under the condition of hyperchloramphenicol, Thauera,Pseudomonas and Azoarcus are the main heterotrophic denitrifying microorganisms, Sulfurovum and Thiobacillus are the main autotrophic denitrifying microorganisms, these microorganisms keep the system good simultaneous removal of sulfur and nitrogen, in addition, extracellular polymers, especially extracellular proteins, increase with the increase of chloramphenicol concentration.
