在三氯蔗糖生产过程中，dmf的回收会产生含dmf的废水，同时在高盐废水处理（蒸发冷凝）的时候也会产生含dmf废水。目前对含dmf废水的处理主要有两种：一种是含dmf废水制稀氨水，但是由于废水当中杂质较多，会造成稀氨水中有其他的特殊气味，同时氨水会发黑，销售压力较大，对前工段dmf回收的影响较大；另一种是直接通往污水站通过厌氧和好氧处理之后到达排放标准后排放，但是由于dmf分解后产生的氨氮较多，造成生化处理的负荷较大，制约了废水处理量，对生产影响较大。

Application: Separation of DMF and Ammonia

In the process of sucralose production, the recovery of dmf will generate wastewater containing dmf, and at the same time, wastewater containing dmf will also be generated during the treatment of high-salt wastewater (evaporative condensation). At present, there are two main types of treatment of wastewater containing dmf: one is to make dilute ammonia water from wastewater containing dmf, but due to the large amount of impurities in the wastewater, it will cause other special odors in the dilute ammonia water, and at the same time, the ammonia water will turn black, and the sales pressure is relatively high. The other is to directly lead to the sewage station through anaerobic and aerobic treatment and then discharge after reaching the discharge standard. However, due to the large amount of ammonia nitrogen generated after the decomposition of dmf, the biochemical treatment The load is large, which restricts the amount of wastewater treatment and has a great impact on production.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. developed a gas chromatography method for the determination of N,N-dimethylformamide and ammonia water with high column efficiency. Good separation and satisfactory results.
