济南护城河景观水体综合治理技术研究

Comprehensive Treatment Technology of Water Environment for Urban Landscape Water Body in Jinan Moat

城市景观水体因多为封闭水体,水体流动性差,自净能力较低,各种水环境问题尤为突出,严重影响了水体的生态环境和城市景观。文章概述了济南护城河区域水环境现状问题,归纳分析了各种问题产生的原因,从水平和垂直两个维度针对性的提出了应急调水提质系统、水面生物絮体清除系统、河道内沉水植被收割装置、河道底泥清除装置等多项治理措施,较好的缓解了护城河各种水环境问题,大大改善了水体景观,对维持城市生态系统的持续、稳定和健康发展起到了积极的促进作用。

Urban landscape water is mostly closed water,with poor mobility and low self-cleaning capacity.All kinds of water environment problems are particularly prominent,which seriously affect the ecological environment and urban landscape.This paper summarizes the current situation of water environment in the moat area of Jinan.It summarizes and analyzes the causes of various problems.From the horizontal and vertical dimensions,the study proposes several treatment measures,such as emergency water-regulating and quality-improving system,water surface bio-flocs removal system,submerged vegetation harvesting device in river course and river bottom mud removal device.It alleviates the water environment problems of the moat,improves the water landscape,and promotes the sustainable,stable and healthy development of the urban ecosystem.
