为减少污染物的排放，实现氮的资源化利用，研究了氮回收与药物去除相结合的畜禽尿处理工艺。将尿素合成亚甲基脲与旋转高级氧化接触器（RAOC）对磺胺类抗生素的吸附和光催化降解相结合，获得安全的肥料和再生水。亚甲基脲合成可以回收合成尿中的脲，然而，几乎所有的磺酰胺类抗生素也被掺入，如果亚甲基脲用作肥料，这从安全性方面来看是不利的。相反，RAOC可以在不消耗尿素的情况下清除磺胺类抗生素。实验还证实了合成尿经RAOC处理后可合成亚甲基脲。因此，我们的结论是，RAOC应插入之前的氮回收过程中的有效处理尿和安全使用的亚甲基尿素作为肥料。
The combination of nitrogen recovery and pharmaceutical removal processes for livestock urine treatment were investigated to suppress the discharge of pollutants and recover nitrogen as resources. We combined methylene urea synthesis from urea and adsorption and photocatalytic decomposition of sulfonamide antibiotic using rotating advanced oxidation contactor (RAOC) contained for obtaining both safe fertilizer and reclaimed water. The methylene urea synthesis could recover urea in synthetic urine, however, almost all sulfonamide antibiotic was also incorporated, which is unfavorable from a safety aspect if the methylene urea is to be used as fertilizer. Conversely, RAOC could remove sulfonamide antibiotic without consuming urea. It was also confirmed that the methylene urea could be synthesized from synthetic urine treated by RAOC. Thus, we concluded that RAOC should be inserted prior to the nitrogen recovery process for effective treatment of urine and safe use of methylene urea as fertilizer.
