摘要
当前地下水硝酸盐污染状况不容乐观。生物反硝化技术作为修复硝酸盐污染的地下水有效方法之一,最为研究者所青睐。而在生物反硝化过程中碳源、C/N比、硝酸盐浓度、温度、p H值及水力停留时间(HRT)等是影响反硝化有效进行的重要因素。本文综述了近年来研究者对影响反硝化因素的研究,同时对今后研究方向进行了展望。
Abstract： The current groundwater nitrate pollution situation is not optimistic. Biological denitrification technique as one of the effective methods of nitrate pollution of groundwater is favoured by most researchers. In the process of denitrification, carbon source and C/N ratio, nitrate concentration, temperature, pH and HRT are the important factors that affect the efficient operation of denitrifying. The researchers of related in recent years is reviewed in this paper and the future research direction is prospected.
