摘要
针对印染废水中存在生化处理出水总氮(TN)偏高的问题。本文以1.5 m3/h的中试装置为基础,采用以乙酸钠为碳源,对缺氧生物滤池的二级出水,通过调整工艺参数探讨其脱氮机理,探索可以获得高效、廉价的深度脱氮除磷污水处理技术。结果表明,乙酸钠为碳源,在微生物的作用下硝态氮大量分解,对脱氮效果有了显著提高。
For the printing and dyeing wastewater, there is a problem that the total nitrogen （TN） in the effluent is too high. Based on a 1.5 m3/h pilot plant, this study uses sodium acetate as the carbon source for the secondary effluent of the anoxic biological filter, and explores the denitrification mechanism by adjusting the process parameters, and explores that an efficient and inexpensive depth can be obtained. Nitrogen and phosphorus removal wastewater treatment technology. The results showed that sodium acetate was the carbon source. Under the action of microorganisms, a large amount of nitrate nitrogen was decomposed and the nitrogen removal effect was significantly improved.
