Abstract:The thesis identified factors which influenced meso-structured nanometer γ-Al2O3 absorption effectiveness, that was water flux time and rate, through dynamic experiment of meso-structured nanometer γ-Al2O3 dealing with SO42-、Cl-、Ca2+ from reusing Zongpai water of used blast furnace circulating cooling water of Baogang. The results showed that SO42- removal rate was 88% when pH=5, flux time was 10 min and flux rate was 15L/h; Cl- removal rate was 75%when pH=5, flux time was 10 min and flux rate was 60L/h; Ca2+ removal rate was 84% when pH=11, flux time was 10 min and flux rate was 60L/h.
