如何有效地从废水中除磷,是人们很久以来研究去除营养物质、防止水体富营养化的内容之一。在众多技术方法中,化学沉淀法和生物法是主要的实用方法。在人们还未普遍了解生物法除磷机理以前,在废水处理中常常使用有效、可靠的化学沉淀法。自八十年代以来,生物除磷的研究取得了很大的发展,世界各国出现了许多生物除磷污水处 How to effectively remove phosphorus from waste water has long been one of the topics that people study to remove nutrients and prevent water eutrophication. Among many technical methods, chemical precipitation and biological methods are the main practical methods. Before people generally understand the biological phosphorus removal mechanism, effective and reliable chemical precipitation methods are often used in wastewater treatment. Since the 1980s, great progress has been made in the research of biological phosphorus removal. Many biological phosphorus removal sewage plants have emerged in various countries in the world
