Abstract

To realize improved wastewater treatment processes, the study investigated the processing of boron and fluorine and the processing of real landfill leachate using MgO with different specific surface areas. By optimizing the MgO absorbent, the time required for boron and fluorine processing can be reduced dramatically and uniform wastewater quality standards can be achieved. The rate constants for boron and fluorine removal increased with both temperature and specific surface area. In the processing of actual wastewater, which contained many coexisting ions, MgO was successfully applied to the removal of boron.
