污水中磷回收方法研究进展∗

摘要

Phosphorus resources, as important raw materials in national production and life, are ev⁃er⁃decreasing, and cannot be renewed in nature in a short term. But in sewage, there is a large a⁃mount of phosphorus, which will result in eutrophication of water body. In this sense, recycling of phosphorus in sewage with proper technology will not only lessen environmental pollution, but make up for deficiency of phosphorus resources as well, showing great practical importance. This paper summarizes current situations, basic principles and influencing factors of phosphorus recovery tech⁃nology, and explores research directions of every recycling method.%作为国民生产和生活的重要原料，磷资源日益减少，在自然界中短期无法再生，而在污水中却含有大量的磷，并随着污水的排放造成水体富营养化。如果采用适当的方法将磷从污水中回收出来，既减少了环境污染，又弥补了磷资源的不足，具有十分重要的现实意义。文中就目前污水中磷回收方法的现状、原理及其影响因素进行了总结，并对这些方法的研究方向进行了展望。
