瓦埠湖陡涧河湿地生态系统构建设计

陡涧河生态湿地设计思路:采用应用范围广的"垂直流人工湿地+表面流人工湿地"的组合工艺,另外,考虑进水需进行水质水量的调节和去除悬浮物,在工艺前加上稳定塘;选择钢渣、活性炭作为吸附填料,选择沙石等作为基质填料;选择芦苇(Phragmites australis)、花叶芦荻(Arundo donax)、千屈菜(Lythrum salicaria)、香蒲(Typha orientalis)、再力花(Thalia dealbata)、美人蕉(Canna indica)和风车草(Cyperus alternifolius)为湿地植物。在进水口设进水总闸,将稳定塘布置在鱼塘上,出水口布置在塘区下游最窄处,并将其一部分坝体建成漫水坝,另外段建成高于水面的河堤。

Wetland Ecosystem Construction Design of the Doujian River in the Wabu Lake

Ecological wetland design of the Doujian river:A wide range of applications "vertical flow constructed wetland+surface flow constructed wetland" a combination of technology,in addition,consider the water need of water quality and quantity regulation and remove suspended solids,before the process coupled with a stable pond;Steel slag,activated carbon adsorption was selected as a filler,the gravel as a base filler;Phragmites atstralis,Arundo donax,Lythrum salicaria,Typha orientalis,Thalia dealbata,Canna indica and Cyperus alternifolius were choosen as wetland plants.Water inlet total brake was set in intake of water gate.The stabilization pond was decorated in the fishpond.The outlet was arranged in pond area of the downstream narrowest place,and would be part of overflow dam,and the water bank would be built above the surface of the river.
