Abstract：

There investigated the emulsion liquid membrane formulations treating coking wastewater through the system about Span-80、Tween-80 and carbon tetrachloride as the main raw material in this paper Compared with the emulsion liquid membrane formulations treating coking wastewater through Span-80 as a single surfactant. Different factors effecting on extraction rate of NH3-N are investigated, such as the type of emulsifier, HLB value, the amount of emulsifier, concentration of H2SO4, draw optimal conditions: The HLB of the surfactant is 5.19 and the amount of surfactant is 0.8g, concentration of inner water phase is 0.25mol/L, the effect on the removal rate of NH3-N in coking wastewater using emulsion liquid membrane is 99.9%. Furthermore, Through comparing of two emulsion liquid membranes which treating coking wastewater suggest that the removal rate of NH3-N for the mixed surfactant is better than the single.
