| 简介 |
PROBLEM TO BE SOLVED : To provide a method for treating boron-containing wastewater, capable of efficiently removing boron from boron-containing wastewater and capable of enhancing the sedimentation properties of sludge.
SOLUTION : In the method for treating the boron-containing wastewater in the coexistence of a rare earth element solution and an aluminum salt solution to form a precipitate and subjecting the formed precipitate to solid-liquid separation to remove boron, the coexisting ratio of the effective component R2O3 of the rare earth element solution and the effective component Al2O3 of the aluminum salt solution is set to Al2O3/R2O3=0.05 to 0.5. |
