摘 要:
The decontamination of ammoniacal nitrogen in wastewater from process of cyanuric chloride with emulsion liquid membrane was studied. Factors affecting efficiency of removal of ammoniacal nitrogen were investigated with a selected system of liquid membrane. Experimental results showed that ammoniacal nitrogen in the wastewater from process of cyanuric chloride with a concentration 1114 mg/L can be reduced by as much as 97% with the emulsion liquid membrane consisting of that the polyamine surfactant 6%(mass fraction), additive 10%(volume fraction), H2SO4 solution 10%(volume fraction) and Roi of 2:l(by vol) under the operation condition followed: Rtw of l:8(by vol), pH 11.8 and retention time of 15 minutes.
