Abstract: An ammonium wastewater treatment technology in the production of hydrazine hydrate is introduced. The BH-type high efficiency packing was used in revamping an existing ammonium wastewater treatment system. The results indicated that organic material could be stripped from waste water at the stripping section and concentrated at the rectification section to meet the recovery requirement. The mass concentration of ammonia in the overhead reached 4%—8% and could be recovered. At the same time; the waste water could be recycled since the mass concentration of ammonia in the bottom was reduced to 20—50 mg/L，much lower than discharge standard.

摘要： 介绍了水合肼生产氨氮废水处理达标技术，研究了BH型高效填料在有机厂氨氮废水处理老系统改建中的应用。结果表明：利用物理方法通过气提方式，可以在提馏段将NH3从废水中气提出来，在精馏段通过精馏将有机物料浓缩，使塔顶NH3含量达到4%～8%，达到回收利用的目的；塔底废水中NH3含量降至20～50 mg/L，达到并超过排放要求，此水达到纯净程度，可以回收利用。
