Analysis of Influencing Factors on Synchronous Nitrogen and Phosphorus Removal in Sewage Purification Using Subsurface Flow Constructed Wetland Substrate

分析与研究了潜流人工湿地基质同步脱氮除磷效果因素的利弊,对这些因素从湿地内部组分、湿地外部环境和湿地运行调控三个方面进行考察。在湿地内部组分方面,包括潜流人工湿地类型、植物和微生物的影响。这些组分直接参与人工湿地脱氮除磷过程和间接为基质构建不同的脱氮除磷环境,对其效果产生影响。湿地外部环境主要考虑温度和pH值。温度和pH值可以影响人工湿地的生化过程和微生物代谢活性,从而影响基质同步脱氮除磷效果。湿地运行调控主要考虑水力负荷率和水力停留时间。合理的水力负荷率和水力停留时间可以提供适宜的环境条件,有利于人工湿地基质对氮和磷的同步去除。通过深入分析和研究这些影响因素,可以为优化潜流人工湿地的设计与运营提供科学依据,并提高对水体中氮和磷的去除效率。

The analysis investigated the advantages and disadvantages of factors that synchronize the effectiveness of nitrogen and phosphorus removal in the substrate of a submerged constructed wetland.The factors were examined in terms of the wetland's internal components,external environment,and operational regulation.The wetland's internal components,such as the type of submerged flow artificial wetland,plants,and microorganisms,play a direct role in the removal of nitrogen and phosphorus.The wetland's internal components,such as the type of submerged flow artificial wetland,plants,and microorganisms,play a direct role in the removal of nitrogen and phosphorus.They also indirectly impact the creation of different removal environments for the substrate,affecting its effectiveness.The wetland's external environment,including temperature and pH,is also a crucial factor to consider.Temperature and pH can affect the biochemical processes and microbial metabolic activity of the constructed wetland,thereby influencing the efficiency of simultaneous nitrogen and phosphorus removal from the substrate.Wetland operation regulations primarily consider the hydraulic loading rate and hydraulic retention time.Suitable environmental conditions for the synchronous removal of nitrogen and phosphorus by the substrate of the constructed wetland can be achieved through reasonable hydraulic loading rates and hydraulic retention times.Analyzing and studying these factors can provide a scientific basis for optimizing the design and operation of submerged flow constructed wetlands,thereby improving the removal efficiency of nitrogen and phosphorus in water bodies.
