新型厌氧氨氧化工艺实现污水同步脱氮与除磷研究进展

    Advances in Novel Anammox Process for Simultaneous Nitrogen Removal and Phosphorus Removal From Wastewater

    • 摘要: 污水脱氮除磷是当前水环境治理领域的重要问题。传统污水脱氮工艺主要依赖硝化与反硝化过程,不仅消耗大量曝气能耗,而且需要有机碳源,伴随剩余污泥产量与日俱增。厌氧氨氧化工艺具有节省曝气能耗和有机碳源、污泥产量低等重要优势,已在高氨氮废水处理领域实现工程化应用。然而,目前厌氧氨氧化工艺应用于主流城市污水处理还面临较多困难,而且厌氧氨氧化菌利用底物的局限性导致其在处理不同种类废水的更广泛领域也存在诸多瓶颈。近年来,基于短程硝化和短程反硝化等途径实现厌氧氨氧化的研究和实践不断开展,为该工艺的实际应用提供了更多可能。厌氧氨氧化脱氮技术与生物除磷及化学除磷等方法相结合,不仅能够实现废水的同步氮磷去除,而且为废水资源回收提供了新思路。该文综合近年来厌氧氨氧化与传统生物除磷、反硝化除磷及化学沉淀法除磷等磷去除相关研究,对不同类型的工艺原理、优势及研究进展做出简要分析,旨在为污水氮、磷营养物高效去除提供理论依据和技术参考。

       

      Abstract: Nitrogen and phosphorus removal from wastewater is a critical issue in the recent field of water environment management. The anaerobic ammonia oxidation (anammox) process offers significant advantages, including saving aeration energy and organic carbon sources and producing less sludge. As the study progressively advances, based on partial nitrification and partial denitrification combining with Anammox processes have been conducted, providing more possibilities for the wide range of practical applications of this process. Combining Anammox technology with biological phosphorus removal and chemical phosphorus removal methods can not only achieve nitrogen and phosphorus removal from wastewater but also offer new ideas for resource recovery. This paper synthesizes the current research status of anammox in recent years, and briefly analyzes the coupling research related to phosphorus removal between anammox and traditional biological phosphorus removal, denitrifying phosphorus removal, and chemical precipitation. It also provides a brief analysis of the principles, advantages, and experimental progress of different types of processes, aiming to offer a theoretical basis and technical reference for efficient removal of nitrogen and phosphorus nutrients from wastewater.
