Research and Progress of Pyrite-Based Autotrophic Denitrification
摘要: 氮是污水排放中控制的主要污染物之一。生物脱氮是控制氮排放的有效且经济的方法。和传统生物脱氮相比，硫自养脱氮技术具有节约碳源、污泥产量少、运行能耗小的突出特点。本文阐述了硫铁矿自养脱氮技术的原理和优势，综合评述了自养脱氮过程中的关键参数和影响因子，比较分析了几种不同自养脱氮反应器的运行特性和效能差异，指明了今后硫铁矿自养脱氮技术在污水深度处理中的研究重点和发展方向。
Abstract: Nitrogen is one of the major contaminants in sewage, to which biological denitrification is an ef-fective and economic solution. Compared to classic denitrification, the sulfur-based autotrophic denitrification consumes less energy and carbon source with less sludge production. Thus, this essay will illustrate its theory and the main parameters, showing the impact factors of the py-rite-based autotrophic denitrification process. Moreover, three different reactors are analyzed for their differences of denitrification performance and operation, which leads to a new research di-rection of this advanced water treatment.
