In this paper, the Chromium_containing wastewater treatment with rectorites as adsorption reagent and with FO2 as redacting reagent has been studied. The sorption behavior of rectorites for chromium (Ⅵ) also were investigated. The result of the experiment shows that under the condition without changing its pH, the amount of the rectorites in 2.5g/L, FO2 0.5 g/L, it can make the wastewater reach the standard and drain off. It 's more economical. The sorption behavior of rectories for chromium (Ⅵ) obeys the Freundlich, lgQ=-1.9102 + 0.3545 lgC.
