摘要
对于因人类活动的影响,氮、磷等营养物质大量排入水体并在其中不断积累,引起部分藻类和水生生物过度繁殖,造成湖泊的富营养化现象,成为日益突出的环境问题。着重从控制外源输入、降低内源负荷、去除营养物等3个方面,对现有的湖泊富营养化防治措施进行了概括和比较,对今后可能的发展方向进行了展望,并提出了综合防治策略。
As a result of human's actions and impacts on environment, a plenty of nitrogen and phosphorus are discharged into water and accumulates incessantly, which causes excessive multiplications of some algal and hydro bios. All of these lead to lake eutrophication which has been an increasingly emergent issue of environment. This paper emphasized the existing preventions, controls and treatments related to control of extraneous sources, decrease of endogenous load and removal of nutrient substances. Based on the summarization and compare, relevant direction of development for the future was discussed, and comprehensive strategy was also put forward.
