    • The invention relates to a method for treating triazine-containing water of a melamine plant. Said method is characterized in that the water containing ionic and non-ionic triazines in a dissolved form is fed to at least one membrane filtration unit (MF), the water is separated into an ionic triazine-rich fraction and a non-ionic triazine-rich fraction in the membrane filtration unit (MF), whereupon the ionic triazine-rich fraction is discharged and the non-ionic triazine-rich fraction is redirected into the melamine plant. The inventive method allows a great portion of the melamine contained in the triazine-containing water to be redirected into the process while the yield is increased along the entire melamine process. Furthermore, the need for fresh water in the wet part of the melamine plant is decreased. The disclosed method can be carried out continuously and in liquid phase.
    • 本发明涉及一种处理三聚氰胺植物含三嗪水的方法。 所述方法的特征在于,将含有溶解形式的离子和非离子三嗪的水加入到至少一个膜过滤单元(MF)中,将水分离成富含离子三嗪的级分和非离子三嗪 - 膜过滤单元(MF)中的富含部分,然后排出富含离子三嗪的级分,并且将非离子三嗪富集部分重新引导到三聚氰胺植物中。 本发明的方法允许包含在含三嗪的水中的大部分三聚氰胺被重新引导到该过程中,同时沿整个三聚氰胺过程增加产率。 此外,在三聚氰胺植物的湿润部分中需要淡水。 所公开的方法可以连续地和液相地进行。
