液固比对沼渣协同硫酸亚铁修复Cr(Ⅵ)污染土壤的影响

Effects of Liquid-Solid Ratio on Remediation of Cr(Ⅵ) Contaminated Soil by Using Biogas Residue in Coordination with Ferrous Sulfate


摘要(Abstract):

通过污染土壤修复模拟实验,研究25℃恒温条件下液固比对沼渣协同硫酸亚铁修复Cr(Ⅵ)污染土壤的Cr(Ⅵ)还原稳定效果的影响。结果表明:Cr(Ⅵ)去除率随着液固比的增大而增大,当液固比为6∶1时Cr(Ⅵ)去除率最大;Cr(Ⅵ)还原反应发生在以氧化还原为主的初期,后续生物还原Cr(Ⅵ)缓慢持续进行直至稳定,最终铬元素以稳定态即铁锰氧化态和残渣态形式存在,液固比对Cr(Ⅵ)的还原影响差异不显著;不同液固比组间的微生物组成和丰度差异不显著,微生物变化均发生在反应1 d即Cr(Ⅵ)的主还原阶段,当液固比为6∶1时,优势菌门拟杆菌门相对丰度增至21.31%,优势菌属嗜冷杆菌属相对丰度增至18.98%,微生物组成和丰度变化较显著。
