| 摘 要： | 为了明确系统中反硝化脱氮的具体途径，在传统活性污泥工艺物料衡算方法的基础上，构建了基于短程硝化、同步硝化反硝化和反硝化除磷耦合技术的新型物料平衡系统。以AAO工艺为例，计算了系统稳定运行期间，碳、氮和磷的物料流向，量化了反硝化的5种脱氮途径。结果表明，通过物料衡算推导，系统短程硝化（PN）效率为64．36％。同步硝化反硝化（SND）效率为57．37％；反硝化除磷（DPR）效率为7．82％。对反硝化途径的分析发现，通过亚硝酸盐型同步硝化反硝化去除的氮占32．7％，而作为除磷电子受体得到去除的氮占11．4％。

| Abstract: | In order to specify the precise pathway of denitrification, a new mass balance system, coupled with partial nitrification （PN）, simultaneous nitrification and denitrification （SND） and denitrifying phosphorus removal （DPR） , was built on the basis of the mass balance method of conventional activated sludge process. Taking AAO process for example, during the stable operation period, mass flow containing carbon, nitrogen and phosphorus was defined, and five forms of denitrification pathway were quantified. The result shows that efficien- cies of PN, SND and DPR calculated by mass balance are 64.36% , 57.37% and 7.82% , respectively. Based on the analysis of denitrification pathway, nitrogen removal rates via nitrite in SND and electron acceptor in DPR are 32.7% and 11.4% , respectively. |
