氮肥工业废水中氨氮硝化速率的研究

Research about Nitrification Rate of Ammonia Nitrogen in Nitrogen Fertilizer Industry Wastewater

介绍了氮肥工业废水的水质特征和处理现状。生化处理过程中,由于其高氨氮水质的原因,氨氮硝化速率成为一个关键的影响因素,文中对氨氮硝化速率进行了重点介绍和分析研究,并通过文献资料和实验研究建立了氨氮硝化速率q与BOD5/TKN的模型方程,该方程的建立将对氮肥工业废水的处理设计有一定的指导意义。

The characteristics of water quality and status quo of the treatment of nitrogen fertilizer industry wastewater are introduced. In the process of biochemical treatment, the nitrification rate of ammonia nitrogen became one key influencing factor because of ammonia nitrogen is rich in the wastewater. As emphasis on the nitrification rate of ammonia nitrogen is introduced and discussed in the paper. Furthermore, a new mathematical model about nitrification rate of ammonia nitrogen and BODJTKN was established based on some literature material and experimental research. The model will provide some guidance in the engineering practice of nitrogen fertilizer industry wastewater.
