5.SHARON－ANAMMOX组合工艺
SHARON－ANAMMOX组合工艺具有耗氧量少、污泥产量少、不需外加碳源等优点，是迄今为止最简捷的生物脱氮工艺，具有很好的应用前景，成为当前生物脱氮领域内的一个研究重点。

致受纳水体富营养化的主要原因之一。常规的污水处理技术主要去除有机物和悬浮固体，对氮和磷的去处效率较低。许多发达国家对排放污水中的氮和磷含量都做了限定，并要求污水处理厂达到除氮除磷的要求。生物处理是废水处理中应用最为广泛的技术。与处理其他对象如固体废弃物、废气等的生物处理技术相比研究更加深入，技术更加成熟。根据不同污水的特点，通过对上述生物脱氮除磷新技术与工艺的选择与集成，能够有效地从污水中同时去除氮、磷和有机污染物。
