摘要

For the removal of acid wastewater from in-situ leaching of uranium (UAW), this study presents a new method of synergistic microbial remediation via electric power, which utilizes the dual action of electricity and bacteria to achieve the removal 98% of uranium, 90% of SO42−, and heavy metal ions from wastewater while alleviating the acidic conditions of the wastewater. Compared with electric remediation alone, the stability was significantly improved, and the effect of groundwater acid reflux on the remediation effect was effectively mitigated, while the use of electric field compensated for the long cycle time of the microbial remediation process.
