摘要
介绍了污水除磷的几种主要方法,并对化学沉淀法除磷技术和生物除磷技术以及人工湿地除磷技术进行了详细论述,简要分析了各种方法的利弊:化学法除磷效率较高,但会产生大量化学污泥;生物法除磷操作简单,但除磷效率较低;人工湿地除磷技术廉价高效,但有待进一步发展完善。
Introducing several main dephosphorization methods of wastewater,the paper discussed chemical deposition dephosphorization method,biological dephosphorization method and constructed wetland dephosphorization method in detail and analyzed their advantages and disadvantages, chemical deposition dephosphorization has higher phosphorus removal rate, but it will bring a large mount of sludge; biological dephosphorization is more convenient for operation , but phosphorus removal rate is lower; constructed wetland is a low-cost technique to remove phosphorus, but it should be developed.
