废水生物脱氮技术探讨

随着人们生活水平的日益提高，所排放的氮化合物对水质的影响越来越大。中国“十二五”期间也将增加氮化合物的削减任务，所以废水生物脱氮技术也就成了日后水污染治理的焦点问题，目前国内外研究的热点主要集中在如何改进传统的硝化－反硝化工艺，提出了适合低碳高氨氮废水生物脱氮的新工艺。通过综述传统生物脱氮原理及工艺，短程硝化－反硝化脱氮技术和同步硝化－反硝化技术，对各种废水生物脱氮工艺进行了探讨。

Biological Denitrification of Wastewater Technology

As people＇s living standard rising, the emissions of nitrogen compounds increasing impact on water quality, our country, ＂Shier Wu＂ period will also increase the reduction of nitrogen compounds task, wastewater biological nitrogen removal technology has become of the future the focus of water pollution problems, the research hotspot at home and abroad focused on how to improve the traditional nitrification - denitrification process was proposed for low - carbon high strength ammonia wastewater of new biological nitrogen removal process. Overview of biological nitrogen removal by the traditional principles and processes, nitrification - denitrification technology and simultaneous nitrification - denitrification technology, a variety of wastewater biological nitrogen removal process were discussed.
