The removal of ammonia nitrogen from salt-containing wastewater by Donnan dialysis has been studied. The effects of initial salt concentration,concentration ratio of Na Cl to NH4+,stirring intensity and temperature on ammonia nitrogen separation were investigated. The results showed that the removal efficiency of ammonia nitrogen was improved with the reduction of initial salt concentration and concentration ratio of Na Cl to NH4+. When the stirring intensity increased from 200 r/min up to 500 r/min,the sep...
