Abstract：
Coking wastewater (CWW) treatment is difficult due to its complex composition and high biological toxicity. Iron-carbon mediators was used to enhance the treatment of CWW through iron-carbon microelectrolysis (ICME). The results indicated that the removal rate of COD and phenolic compounds were enhanced by 24.1 % and 23.5 %, while biogas production and methane content were promoted by 50 % and 7 %. Microbial community analysis indicated that iron-carbon mediators had a transformative impact on the reactor\'s performance and dependability by enriching microorganisms involved in direct and indirect electron transfer, such as Anaerolineae and Methanothrix. The mediator also produced noteworthy gains in LB-EPS and TB-EPS, increasing by roughly 109.3 % and 211.6 %, respectively. PICRISt analysis demonstrated that iron-carbon mediators effectively augment the abundance of functional genes associated with metabolism, Citrate cycle, and EET pathway. This study provides a new approach for CWW treatment.
摘要：
焦化废水(CWW)成分复杂,生物毒性大,处理难度大。铁碳介体用于通过铁碳微电解（ICME）增强CWW的处理。结果表明，COD和酚类化合物的去除率分别提高了24.1%和23.5%，而沼气产量和甲烷含量分别提高了50%和7%。微生物群落分析表明，铁-碳介质通过富集参与直接和间接电子转移的微生物对反应器的性能和可靠性有转化性影响。如Anaerolineae和Methanothrix。调解人还在LB-EPS和TB-EPS方面产生了显著的增长，增长约109.3%和21.6%，分别。PICRISt分析表明，铁-碳介质有效地增加了与代谢相关的功能基因的丰度，柠檬酸盐循环,和EET途径。本研讨为CWW的医治供给了新的办法。
