摘要
水体富营养化是一个全球关注的问题,面源、点源和原位污染所产生的营养物,严重恶化了湖泊水生生态系统。因此,本文首先简述了湖泊富营养化对生态系统的危害,如营养物质富集诱导蓝藻形成、水体缺氧和水华毒素释放,并导致毒素在水生生物和人体中累积,对人体健康构成威胁。其次,本文概述了蓝藻生长的影响因素,其主要受到营养物质富集、温度、阳光、盐度、重金属等因素影响。最后,本文介绍了治理面源、点源和原位污染所引起的湖泊富营养化的生态修复技术,重点论述了生态修复剂修复、水生植物修复、水生动物生态修复等末端生态修复技术,并结合工程知识与理论,提出面源污染末端治理的具体解决方案。
Eutrophication is a global concern because the nutrients generated from non-point,point,and in-situ pollution seriously worsen the lake aquatic ecosystems.Therefore,this paper fi rst briefl y describes the harm of lake eutrophic to the ecosystem.Nutrient enrichment induced the formation of cyanobacteria,hypoxia and the release of bloom toxins,leading to their accumulation in aquatic organisms and human body,and poses a threat to human health.Secondly,the factors affecting cyanobacteria growth are summarized,which are mainly affected by nutrient enrichment,temperature,sunlight,salinity,heavy metals and other factors.Finally,this paper introduces the non-point source,point source and in situ pollution caused by eutrophication corresponding ecological restoration technology,mainly discusses the ecological restorative agent,aquatic plants,aquatic animal ecological restoration terminal ecological restoration technology,combining engineering knowledge and theory,to nonpoint source pollution at the end of the concrete solution.
