| Abstract: | The principle of treating chromium-containing wastewater with coupled anion-exchange resin columns was introduced and the factors influencing the handling capacity of anion-exchange resin were discussed.When the optimal pH value and flux of the experimental wastewater was 3.5 and 10VB/h respectively,coupled anion-exchange resin columns were serialized and saturated to recover chromium-containing wastewater.The permeability was high and processed water could meet national discharge standards.Then cation-exch... |
