摘　　要：综述了尿素废水处理及回收利用的技术进展,主要包括化学法和生物法两大类。化学法如CeO2和尿素的复合催化剂,在低温无氨条件下实现了高效脱硝;生物法如脲酶水解法和生物水解法,通过微生物的降解作用分解废水中的尿素。然而,现有技术仍面临诸多挑战,如技术提升、经济成本等。因此,未来研究应注重技术创新和成本控制,以实现尿素废水的高效处理和尿素的回收利用,促进环境保护和资源再利用。This paper summarizes the technical progress of urea wastewater treatment and recycling,mainly including chemical methods and biological methods.Chemical catalysts such as CeO 2 and urea achieve high efficiency denitrification at low temperature without ammonia.Biological methods such as urease hydrolysis and biological hydrolysis break down the urea in wastewater through the degradation of microorganisms.However,the existing technologies still face many challenges,such as technology improvement,economic costs and so on.Therefore,future research should focus on technological innovation and cost control to achieve efficient treatment of urea wastewater and urea recycling,and promote environmental protection and resource reuse.
