反硝化细菌对甲胺废水的净化作用

The Purification Effect of Denitrifying Bacteria on Methylamine Wastewater

摘要: 根据实验所用甲胺废水的pH值，设置一组pH梯度.在不同pH值(11、10、9、8)条件下，利用已分离的反硝化细菌对甲胺废水进行净化.结果表明：当pH=8时，氨氮去除率可达92.5%.化学需氧量（CODCr）可降低78.3%，色度降低74.5%

Abstract: The pH value of methylamine wastewater used according to the experiment, a set of pH gradient（11, 10, 9, 8）were set up. Under the condition of different pH, the separated denitrifying bacteria was used to purify methylamine wastewater.The results showed that total nitrogen (NH3-N) removal rate can reach 92.5%, chemical oxygen demand (CODCr) can reduce 78.3%, chromaticity can reduce 74.5% in pH=8
