填料除磷是人工湿地除磷的主要方式。对填料自身的理化性质和外界环境因素对其除磷效果的影响进行了探讨,认为填料除磷性能由其自身的理化性质决定,并且受到pH、水力条件、温度、溶解氧、进水磷负荷、竞争离子、进水有机负荷、设计运行情况、植物与微生物等诸多因素的共同影响。
Phosphorus removal by substrates'adsorption in constructed wetlands was widely accepted as the most significant way. This paper talked about the influence of phosphorus removal which was caused by substrates'physical and chemical characters and environmental factors. It held that the effects of phosphorus removal were not only decided by the substrates' physical and chemical characters,but also influenced by pH, temperature,DO, hydrodynamic condition,influent phosphorus loadings,competing ion ,volumetric loading rate,design operation,plant and microbiology and some other factors together.
