| 摘 要： | An advanced cost-saving method of removal of high-As(Ⅲ) from SO4(-Ⅱ)-rich metallurgi cal wastewater has been developed by diluting the SO4(-Ⅱ) content with As(Ⅲ)-Cl(-Ⅰ)-rich metallurgical wastewater and then by the direct precipitation of As(Ⅲ) with Fe(Ⅲ) at pH2.3.As(Ⅲ) removal at various SO4(-Ⅱ)/Cl(-Ⅰ) molar ratios and temperatures was investigated The results showed that 65.2–98.2%of As(III) immobilization into solids occurred at the SO4(Ⅱ)/Cl(-Ⅰ) mo...
