摘　　要：随着国家污水排放标准的提升,污水处理厂生化池需要投加碳源来提高总氮去除率,做好生物反硝化,实现出水达标排放。研究生化系统使用单一碳源或者复合碳源进行生物反硝化时总氮和硝态氮去除效率,可以为污水处理厂选择碳源提供参考,提高生化系统总氮去除率,降低污水处理厂运行成本。With the improvement of national sewage discharge standards,carbon sources need to be added to the biochemical tanks of sewage treatment plants to increase the total nitrogen removal rate,carry out biological denitrification,and achieve effluent discharge standards.Studying the removal efficiency of total nitrogen and nitrate nitrogen in biological denitrification using a single or composite carbon source in biochemical systems can provide reference for selecting carbon sources for sewage treatment plants,improve the total nitrogen removal rate of biochemical systems,and reduce the operating costs of sewage treatment plants.
