摘要
阐述了几种尿素生产废水处理工艺技术,通过比较分析,得知生物水解法处理尿素废水具有工艺简单,运行费用低,处理效果好等特点,采用SBR工艺及两级BAF工艺去除尿素废水,对尿素的去除率分别为90%、85%以上。
This paper describes several urea wastewater treatment technology.Through comparison and analysis, it is concluded that the biodegradation of urea wastewater has the advantages of simple process, low running cost and good treatment effect.SBR process and two-stage BAF process are used to remove urea Wastewater, the removal rate of urea were 90%, 85% or more.
