摘要

摘要: 采用连续流分段进水短程反硝化-厌氧氨氧化（partial denitrification-anaerobic ammonium oxidation，PD-Anammox）耦合反硝化工艺处理低C/N生活污水，研究了污染物去除、典型周期COD及氮素沿程变化特征、短程反硝化-厌氧氨氧化和反硝化对TN去除贡献。结果表明：在平均进水ρ（COD）、ρ（NH₄⁺-N）、ρ（TN）为193.1，58.6，60.3 mg/L的条件下，系统出水平均ρ（COD）、ρ（NH₄⁺-N）、ρ（TN）分别为46.3，1.5，13.4 mg/L，低于GB 18918—2002《城镇污水处理厂污染物排放标准》一级A标准。采用NO₃^--N预缺氧和进水点后置，可实现缺氧区NO₃^--N→NO₂^--N转化，同时完成厌氧氨氧化过程；缺氧区设置厌氧氨氧化悬浮填料，可提高系统TN去除率。通过缺氧区物料衡算，缺氧1区厌氧氨氧化对TN去除贡献率（ΔPD-Anammox/ΔTN）均值为54.37%，缺氧2区的ΔPD-Anammox/ΔTN均值为64.17%。

Abstract: The low C/N domestic sewage was treated by a step-feed continuous flow partial denitrification-anaerobic ammonium oxidation (PD-Anammox) process coupled with denitrification, the pollutants' removal characteristics, pollutants' concentrations in different stages of the system at a typical operation cycle, and total nitrogen(TN) removal contribute efficiencies of PD-anammox and denitrification were studied. The results showed that when the average influent concentrations of COD, NH₄⁺-N, and TN were 193.1, 58.6 and 60.3 mg/L respectively, their effluent concentrations were 46.3, 1.5, and 13.4 mg/L respectively, complying with the first level A criteria specified in the Discharge Standard of Pollution for Municipal Wastewater Treatment Plants (GB 18918-2002). The nitrate transformed to nitrite in anoxic by nitrate pre-starvation and post-inlet to provide the anammox matrix of nitrite and ammonium. The TN efficiency got improved by setting anammox filler in the anoxic zones. The average PD-Anammox process's contribution rates to TN removal of anoxic zone Ⅰ and Ⅱ were 54.37% and 64.17% respectively, through mass balance calculation at the anoxic zones.
