【摘要】：目前我国实际污水处理反硝化过程碳源不足,需要外加碳源以保证充分反硝化。近几年新型碳源由于成本较低,其研究发展迅速。常见的新型碳源即纤维素类碳源、工业废水和垃圾渗滤液以及一些其他物质碳源的反硝化特性总结于文中。尽管一些固体类的新型碳源对后续处理造成一定困难,部分新型碳源不适用于生活污水反硝化,但大多数新型碳源成本较低,能利用某些废弃物补充污水反硝化所需碳源,具有一定的环保效应,应用前景较为广泛。
[Abstract]:At present, the carbon source in the process of denitrification is insufficient in our country, which needs additional carbon source to ensure full denitrification. In recent years, the new carbon source has developed rapidly because of its low cost. The denitrification characteristics of cellulose carbon sources industrial wastewater landfill leachate and some other carbon sources are summarized in this paper. Although some new carbon sources of solids cause some difficulties in subsequent treatment, and some of the new carbon sources are not suitable for denitrification of domestic sewage, most of the new carbon sources are relatively low in cost and can be used to supplement the carbon sources required for denitrification of sewage. Has certain environmental protection effect, the application prospect is relatively widespread.
