摘　　要：考虑了影响制乳和传质过程的各种因素,针对不同浓度含铬废水(20～100mg/L),摸索出一次处理能达到国家排放标准的液膜法除铬最佳实验条件,同时探讨了液膜法除铬机理。Various factors affecting emulsion—making and mass—fransfer were systematically considered. The optimum conditions under which the chromium—containing wastewater can attain the national discharge standard by once—through treatment with liquid membrane were probed into for wastewaters with different concentrations. Meanwhile, the chromium removal mechanism was inquired into too.
