【摘要】 磷的氧化态和还原态都不可能成为气态,一般只能通过化学或者生物学的方法将其作为一种固体收集。除磷技术中,一是利用沉淀反应,或结晶、吸附等作用,二是利用微生物的作用。前者包括化学凝聚法、离子交换法、吸附法和结晶法等,后者包括生物法、Phostrip法、Bardenpho法和Phoredox法。更多还原

【Abstract】 The oxidation state and reduction state of phosphorus can’t become gas state.Normally we collect the phosphorus as a kind of solid by the way of chemistry and biology.Among the technologies on removal of phosphorus,some are the precipitation reaction,the absorption and the crystallization,and other ways,such as the utilization of microbios.The chemical ways include chemical coagulation method,iron exchange method,adsorption method and crystallization method.The biologic ways inculde biology method,Phostrip method,Bardenrho method and phoredox method.更多还原
