摘　　要：为了减轻外加商业碳源给生物反硝化带来的经济负担,降低生物反硝化法的处理成本,需要寻找无毒且更为廉价的碳源以及探寻具有可持续发展前景的强化生物脱氮技术,以取消或减少外部碳源的添加。阐述了目前已投入使用的几种新型碳源以及无外加碳源的序批式生物膜反应器(SBBR)脱氮工艺、两级序批式反应器(SBR)脱氮工艺和其他改进工艺。通过新型廉价碳源的合理利用及组合生物脱氮工艺技术的开发,可以在自有碳源有限的条件下提高生物脱氮效率。In order to reduce the economic burden of adding carbon source for biological denitrification and the processing cost of the biological denitrification method, innoxious and economical carbon source, and sustainable methods for enhanced denitrification are needed to be explored to cancel or reduce external carbon source. Several new types of carbon sources put into use and the denitrification processes without external carbon addition such as SBBR, two-stage SBR denitrification process and other modified processes were expounded. Through the reasonable utilization of new and cheap carbon source and development of integrated biological denitrification process, efficiency of biological denitrification can be improved under limited carbon source.
