摘　　要：综述除磷不同方法的原理、特点及其适用范围。物化除磷法由于其除磷效果好、运行稳定、易实现自动化等特点,适用于处理流量不是很大的含磷废水;生物除磷法可减少活性污泥的膨胀、污泥产出量少、节约能源、运行费用较低,是目前流行的除磷方法;膜技术除磷可克服生物除磷法的缺陷、回收纯净的磷盐,是当前研究的热点。提出物化除磷法与生物除磷法相结合必将成为今后的研究趋势。The principle, characteristic and application scope of different kinds of phosphorus removal methods are expatiated. At present,the physicochemical method has advantages of high effciency, stable running and easy automation, so it is suitable for treating phosphorus wastewater of low flow. The biological method is a quite popular because it has many advantages, such as less sludge output amount, saving energy and lower cost. Membrane technology is the hotspot in current study as it can retrieve phosphate and overcome the defects of biological method. The development trend of removing phosphorus from wastewater is prospected, and it can be proposed that the combination of physicochemical method and biological method will become the research hotspot for the furture.
