摘要
湖泊富营养化是当今严重的环境问题之一,导致这一问题的本质原因是氮、磷的过量输入导致初级生产力的增加。当外源磷得到控制后,控制湖泊中内源磷的释放成为解决湖泊富营养化问题的重点。传统控制内源磷释放的方法有多种,如铝盐、铁盐混凝沉淀法,底泥覆盖法等,这些方法可能产生磷的重新释放、二次污染等问题。锁磷剂对控制内源磷的释放表现出明显优势,具有控磷效果好、无污染、无生态风险等特点,具有广阔的应用前景。本文对最新的锁磷剂研究及应用进展进行概述,以期为控制湖泊内源磷释放提供参考。
Lake eutrophication is one of the acute environmental problems today,and the essence of the problem is the excessive input of phosphorus leading to an increase in primary productivity.When exogenous phosphorus is controlled,controlling the release of endogenous phosphorus in lakes has become the focus of solving the problem of lake eutrophication.There are many traditional methods to control the release of endogenous phosphorus,such as aluminum salt,iron salt coagulation and precipitation method,sediment covering method,etc.These methods may produce problems such as phosphorus re-release,secondary pollution,etc.Phosphorus-locking agent shows obvious advantages in controlling the release of endogenous phosphorus,and has the characteristics of good phosphorus control effect,no pollution,no ecological risk,etc.,and has broad application prospects.This paper summarizes the latest research and application progress of phosphoruslocking agents,in order to provide reference for controlling endogenous phosphorus release in lakes.
