摘要
介绍了除磷的机理,总结归纳了SBR系统中溶解氧、温度、pH值、泥龄、厌氧区的停留时间、硝酸盐、有机物质的浓度、重金属离子的浓度等对除磷的影响,并重点分析了不同重金属离子对SBR系统除磷的影响,最后展望了SBR系统未来在污水除磷及其他方面的发展。
In this article,the mechanism of phosphorus removal was introduced.The effects to phosphorus removal,including solved oxygen,temperature,pH value,nitrate,and the concentrations of organic substances and heavy metals in SBR system,sludge age of the system,and the residence time in anaerobic zone,were summarized.Emphatically the effect of different heavy metal ions to phosphorus removal in SBR system was analyzed.Finally future developments in phosphorus removal for waste water from SBR system and other fields were expected.
