Abstract
The present invention proposes an assembly-type landscape cleaning device suitable for the discharge outlets of decentralized sewage treatment facilities. Floating bed, carrier purification box, porous material, cross cloth water pipe, top planting support frame, fixed rod, outer cloth planting bag, fixed ring, planting bag plant, top planting plate, movable collar; when installing, put the submerged plant box , self-elevating emergent plant floating bed, carrier purification box, cross-shaped water distribution pipe, outer cloth planting bag, and top plant tray are sequentially assembled on the fixed bracket; the invention has high removal efficiency for water outlet pollutants, and the drain pipe is hidden Inside the device, a variety of plants are reasonably matched to create a good landscape effect; the assembly is simple, the installation is flexible and convenient, the cleaning materials can be recycled and replaced freely, the land occupation is small, the construction cost is low, and it can be popularized and applied on a large scale.
Description
technical field [0001] The invention relates to an assembly-type landscape purification device suitable for the outlets of decentralized sewage treatment facilities, and belongs to the technical field of water pollution control. Background technique [0002] Compared with centralized sewage treatment, decentralized sewage treatment mode has unique advantages in vast rural areas with vast areas, scattered population and large investment in pipe network laying. In recent years, small-scale decentralized domestic sewage treatment facilities have played an important role in related projects to improve the rural living environment and regional water environment. However, due to the unstable water quality and quantity of domestic sewage of rural residents, the limited treatment capacity of small facilities, and the pollution cleaning capacity is easily affected by the environment, the drainage water quality of sewage treatment facilities often faces problems such as excessive nitr...
