以纤维素物质为反硝化碳源和载体去除水中硝酸盐

摘要

At present, cellulosic substances as denitrification carbon source and carrier has been a method commonly used for removing nitrate from water. The advantages of the method are low cost, rich material sources and no secondary pollution. The feasibility, influencing factors and technical problems of the solid-phase denitrification technology based on cellulosic substances are discussed,and the developing and research directions,technical problems that need to be solved, as well as drawbacks, of this technology are put forward, providing beneficial reference.%利用纤维素物质作为反硝化碳源和载体是目前去除水中硝酸盐常用的方法,该方法具有成本低廉、取材广、无二次污染等优点.对基于纤维素物质的固相反硝化技术使用的可行性、影响因素以及技术难题等进行了论述,并提出了纤维素物质固相反硝化技术的发展方向和亟需解决的技术难题以及该方法的弊端,为纤维素物质固相反硝化技术的发展和研究提供有益参考.
