摘要
水中过量的磷是造成水体富营养化的主要原因,如何有效除去水体中的磷元素一直是水污染控制领域的研究热点。生物除磷法是目前最普遍的污水除磷方法。生物除磷的效率易受到环境条件和运行条件的影响,而通过投加铁盐可以提高系统的除磷效率和稳定性。本文综述了铁盐对生物除磷系统影响的研究进展,包括污染物去除效果、污泥性质、微生物群落以及作用机理等,以期为生物除磷系统的高效除磷和长期稳定运行提供策略。
Excess phosphorus in water is a leading cause of eutrophication,making its removal a key focus in wastewater pollution control.Biological phosphorus removal is currently the most commonly employed method;however,its efficiency is often unstable and sensitive to environmental and operational conditions.The addition of iron salts has been shown to enhance phosphorus removal efficiency.This paper reviews recent research on the impact of iron salt dosage on biological phosphorus removal systems,including its effects on pollutant removal,sludge properties,microbial communities,and underlying mechanisms.The findings offer strategies for improving phosphorus removal efficiency and ensuring the long-term stability of biological phosphorus removal processes.
