1) Upward vertical flow constructed wetland
2) Vertical flow constructed wetland
Artificial wetland was applied in combination with traditional wastewater treatment technology,and an intensified pre-treatment system was introduced to high-efficiency vertical flow constructed wetland so as to improve the wetland treatment.
The hydraulic pattern of the vertical flow constructed wetland was studied in this paper.
In this experimental study,the vertical flow constructed wetland is employed to treat domestic sewage,rumex acetosa linn is selected as constructed wetland macrophyte.
试验运用垂直流人工湿地工艺处理生活污水,湿地植物选用酸模(学名:Rumex acetosa Linn),间歇进水。
3) vertical flow constructed wetlands
Several kinds of media were utilized in the vertical flow constructed wetlands simulation system to treat wastewater at hydraulic loading rate of 1 000~2 500 mm·d-1,including gravel,zeolite,anthracite,shale,vermiculite,ceramic filter media,blast furnace steel slag and round ceramsite.
4) vertical-flow constructed wetland
According to the operational aspect of Shiyan vertical constructed wetland,this paper analyzed the treatment effect,removal efficiency and economical efficiency of engineering,the main results show that wastewater treatment by using vertical-flow constructed wetland is ef.
The Hunnan vertical-flow constructed wetland can survival through the winter with certain heat preservation measures,exchange air by making use of influent and effluent flow,compensate the oxygen inadequacy of the bed,which improves the removal rates of contaminants and reaches the similar treatment effect to other seasons.
5) integrated vertical-flow constructed wetland
Performance and optimization of recirculating aquaculture system combined with integrated vertical-flow constructed wetland;
Spatio-temporal variation of redox potential(Eh)in the integrated vertical-flow constructed wetland(IVCW)and purification efficiency of pollutants in different function units have been studied.
Aimed at the characteristics of quality and quantity of the Sanjiao Lake water in Jianghan University campus in Wuhan, the integrated vertical-flow constructed wetland process was used to treat lake water in lakeside campus.
6) integrated vertical flow constructed wetland
Studies on Phosphorus Removal in Integrated Vertical Flow Constructed Wetland;
Five kinds of oxidoreductases in the substrate of integrated vertical flow constructed wetland (IVCW) were determined, and the results indicated that there were significant differences in different seasons for oxidoreductases; the enzyme activities of peroxidase were significantly higher in spring, summer and autumn than those in winter (P<0.
Nitrification and denitrification in the different layers of the integrated vertical flow constructed wetlands (IVCW) are studied.
