Abstract

Un método para tratar un líquido residual incluye: una etapa de disolución de aluminio de disolver aluminio en un líquido residual ácido y realizar la separación en una primera agua tratada y un precipitado de metal pesado reducido; una etapa de recuperación de yeso de agregar un compuesto de calcio a la primera agua tratada en una propiedad líquida de un pH de 4 o menos, y realizar la separación en una segunda agua tratada y yeso; una etapa de coprecipitación de metal pesado de agregar un compuesto férrico a la segunda agua tratada y realizar la separación en una tercera agua tratada y un coprecipitado de metal pesado; una etapa de eliminación de aluminio y flúor agregando un álcali a la tercera agua tratada y realizar la separación en una cuarta agua tratada y un precipitado que contiene aluminio y flúor; y una etapa de neutralización de agregar un álcali a la cuarta agua tratada y realizar la separación en un agua tratada de neutralización alcalina y un precipitado neutralizado de un hidróxido de metal pesado.
