| 摘 要： | 文章介绍了将化学沉淀法和液膜法相结合用于高浓度工业氨氮废水的处理。在对沉淀法工艺进行优化的条件下，使氨氮去除率达到98．1％，然后联用液膜法进一步处理使其氨氮浓度降低到0．005g／L，达到国家一级排放标准（〈15mg．L^-1）。该技术具有一定的应用和推广价值。

| Abstract: | The industrial wastewater treatment was studied by chemical precipitation combined with liquid membrane method, which with high concentration of Ammonia-Nitrogen（A-N）. Under the optimized condition of chemical precipitation, the removal rate of A-N is up to 98.1%, and then the liquid membrane will decrease A-N to 0.005g.L^-1, which meeting the national 1^st discharge standard（〈15mg.L^-1）. The technology is useful and can be popularized. |
