摘要

以笔者所在实验室实现部分硝化的生活污水为原水，并作为厌氧序批式反应器（ASBR）进水，在温度为（24±0.5）℃、pH值为8.0~8.2时，通过添加定量的NaNO₂或CH₃COONa，分别考察基质比（NO₂^--N/NH₄⁺-N）、水力停留时间（HRT）和C/N比（COD/NH+4-N）对厌氧氨氧化（Anammox）耦合反硝化脱氮除碳的影响，并采用响应面法探究三者的交互作用。结果表明，当基质比为1.4~1.6、HRT为33h、C/N比为3~5时，系统Anammox的耦合反硝化脱氮除碳效果最佳；方差分析结果显示各因素对总氮去除率（TNR）的影响程度为：C/N比>HRT>基质比；最佳匹配方案：C/N比为4.28，HRT为 33.48h，基质比为1.46，平行试验验证得到的平均TNR为90.12%。

Abstract

The partial nitrificated domestic sewage treated in the autors laboratory was added into the anaerobic ammoxation ASBR reactor as raw wastewater，and NaNO₂ or CH₃COONa was added quantitatively when the temperature was（24±0.5）℃and pH was 8.0~8.2.The effects of NO₂^--N/NH₄⁺-N ratio，hydraulic retention time (HRT) and C/N ratio (COD/NH₄⁺-N) on anammox coupled denitrification and decarbonization were investigated respectively.The interaction among the three factors was explored by response surface analysis method.The results show that，when the NO₂^--N/NH₄⁺-N ratio was 1.4~1.6，HRT was 33 h，and C/N ratio was 3~5，the system's anammox coupled denitrification and carbon removal efficiency were the highest.Analysis of variance (ANOVA) results show that the degree of influence of each factor on the total nitrogen removal rate (TNR) was：C/N ratio>HRT>NO-2-N/NH+4-N ratio.The optimal matching scheme is C/N ratio：4.28，HRT：33.48h，and NO₂^--N/NH₄⁺-N ratio：1.46，and the average TNR verified by parallel experiments was 90.12% .
