内河挖入式港池水体富营养化治理技术

Eutrophication treatment of inland river dig-in harbor basin

内河挖入式港池内水体交换缓慢,富营养化污染问题常有发生,影响港口正常运营和绿色发展。从分析挖入式港池水环境特点、富营养化产生原因入手,阐述兼顾水体治理与景观效果的生态浮岛原理及技术要点。以某内河港池为例,在不影响码头运营的条件下,研究港池生态浮岛治理方案,分析运行费用。初步成果分析表明,通过合理配置生态浮岛,可有效控制水体富营养化、改善水质并营造港池绿色景观,为绿色港区建设提供技术支撑。

The water exchange in the dug-in harbor basin is slow,and eutrophication pollution often occurs,which affects the normal operation and green development of the port.Based on the analysis of the causes and characteristics of water eutrophication in the dig-in harbor basin,we propose an ecological floating island technology which takes the effects of both water treatment and landscape into account,and analyze the effects of ecological floating island technology based on an inland harbor basin.The results show that the reasonable allocation of ecological floating islands can effectively control the eutrophication of water,improve the water quality and create a green landscape of the harbor basin,and it may serve as reference for the eutrophication treatment of inland river dig-in harbor basin.
