Construction and carbon source optimization of a microbial-plant coupled reactor for treating acid mine drainage

Acid mine drainage is one of the most common contamination sources in the non-ferrous metal mining industry. VZC02 and VZC09 in the coupled reactor also assisted with reducing the toxicity of heavy metals to plants by growing the content of heavy metals on the surface of roots, thus improving the plant's treatment effect.

Production of Hydroxyl Radicals from Oxygenation of Simulated Acid Mine Drainage in Presence of Extracellular Polymers Substances

The effect of extracellular polymeric substances secreted by microorganisms on Fe oxidation in AMD is well documented, but no information is available about the effect of extracellular polymeric substances secreted by microorganisms on Fe oxidation in AMD. With an increase in EPS concentration from 0 to 12 mg/L, the cumulative u00b7OH increased from 57. 0 to 158. 70 u00b5M within 24 h at pH 3 with the increase in EPS concentration from 0 to 12 mg/L. In the presence of EPS, Fe with EPS's keystone of OH production is mainly due to the complexity of Fe with EPS, which is full of carboxyl and hydroxyl groups.
