| 摘要: |
| 短程硝化反硝化除磷串联厌氧氨氧化工艺（partial nitrification,denitrifying phosphorus removal and anammox,PNDPR-A）是一种节能高效的新型耦合工艺。为进一步降低污水处理能耗,采用实际生活污水运行PNDPR-A工艺。为适配生活污水,分3阶段（25%、50%和100%）逐步提高生活污水比例。运行初期受生活污水复杂水质影响,短程硝化反硝化除磷单元（partial nitrification, denitrifying phosphorus removal,PNDPR） NH+4-N氧化率下降,NO-2-N积累减少,直接影响后续Anammox单元脱氮效果。针对该问题,提升PNDPR单元好氧1段10%的曝气强度,实现与人工配水时相当的NH+4-N氧化率和NO-2-N积累效果；在阶段Ⅲ,向Anammox单元投加10~20 mg/L的NO-2-N,以缓解阶段Ⅲ初期因PNDPR单元NH+4-N氧化率低导致Anammox单元进水氮素比不理想的限制。经40 d培养驯化,在生活污水中成功启动PNDPR-A耦合工艺,后续系统运行出水平均COD、NH+4-N、NO-2-N和NO-3-N质量浓度分别为36、3.4、5.2和1.1 mg/L,实现了实际生活污水的高效处理。 |

| Abstract: |
| The partial nitrification, denitrifying phosphorus removal and anammox (PNDPR-A) was proposed, which is a new type of efficient energy-saving coupling process. To further reduce the energy consumption of sewage treatment, the PNDPR-A process was adopted for the treatment of actual domestic sewage. The proportion of domestic sewage was gradually increased in three stages (25%, 50%, and 100%) to adapt to actual domestic sewage. Affected by the complex water quality of the sewage in the early stage, the NH+4-N oxidation rate of PNDPR unit decreased and the NO-2-N accumulation was reduced, which directly affected the subsequent denitrification effect of Anammox unit. To tackle this problem, the aeration intensity in aerobic 1 period was increased by 10% for PNDPR unit, so as to achieve NH+4-N oxidation rate and NO-2-N accumulation effect comparable to those of simulated sewage. In phase Ⅲ, 10-20 mg/L of NO-2-N were added to Anammox unit, aiming at alleviating the problem of non-ideal influent nitrogen content of Anammox unit due to the low NH+4-N oxidation rate of PNDPR unit in the early stage. After 40 d of cultivation and domestication, the PNPDR-A process was realized for actual domestic sewage treatment. The average effluent COD, NH+4-N, NO-2-N, and NO-3-N concentrations of the subsequent system were 6,3.4,5.2, and 1.1 mg/L, respectively, indicating the high-efficient treatment of actual domestic sewage. |
