| 摘 要： | 一、概述 尿素合成反应中,每生成1mol尿素同时生成1mol水,加上其它工艺过程排出的水,化肥厂每生产一t尿素大约要排放0.5—0.7t工艺废水,其中含有1—2％的尿素,2—5％的氨。通常先将这股水进行解吸以回收

| Abstract: | Results of the experiments show that denitrifying bacteria were able to hydrolyze urea in the wastcwater into CO2 and NH3 which could he recovered under suitable conditions. Sources of NH3- or organic matters in the waste-water tame from the products of HNO3 or CH3OH. Using the biological reactor filled with fibre, 5000 mg/L urea in the influent was hydrolyzed by 93% in 3 hours, meanwhile 280 mg/L NO3--N was reduced to 120 mg/L. |
