Submerging bed-floating bed coupled water purifying device

Abstract

The invention discloses a submerging bed-floating bed coupled water purifying device. The submerging bed-floating bed coupled water purifying device comprises a submerging bed and a floating bed which are made of UPVC (hard polyvinyl chloride) tubes, wherein the submerging bed comprises upper and lower rectangular frames which are the same in shape; a plurality of perpendicular connecting tubes are arranged between the two rectangular frames; a plurality of horizontal connecting tubes are arranged in the lower rectangular frame; the frames are internally communicated; a floating block capable of being spliced is embedded into the lower rectangular frame, and a planting pot in which submerged plants are planted is arranged on the floating block; a floating block capable of being spliced is also embedded into the floating bed, a planting pot in which emergent aquatic plants are plants is arranged on the floating block, and artificial seaweeds are suspended between adjacent floating blocks of the floating bed; the submerging bed is placed on the center of the inner outline of the floating bed; a connecting rope is arranged between the submerging bed and the floating bed. According to the submerging bed-floating bed coupled water purifying device disclosed by the invention, positions, in water, of submerged plants are regulated by internally watering and pumping the submerging bed, so that the positions of the submerged plants are changed along with ecological niches of water level, transparency and the like, and a natural water environment is simulated to a greatest extent. The water plant planting amount is large, the varieties are rich, the survival rate is high, and the restoration of water body ecological community is facilitated.

Description

technical field [0001] The present invention relates to the ecological reconstruction and restoration technology of natural and artificial rivers and lakes, specifically, to the field of ecological restoration and water quality purification of water bodies with eutrophication and degradation of aquatic plants, and low transparency, especially to a sinking bed- Floating bed coupling water purification technology device. Background technique [0002] In recent years, due to the rapid increase of population and the rapid development of industry, a large amount of nitrogen and phosphorus elements have been input into the water environment, resulting in eutrophication of water bodies and frequent outbreaks of red tide blooms. The ecological environment of the water body deteriorates, the transparency decreases, the distribution area of ​​aquatic plants decreases, the community structure tends to be single, and the ecosystem is already quite fragile. [0003] Emergent plants can ...

Problems solved by technology

But the disadvantage is that the upper and lower layers of the floating bed overlap, and the upper layer will block the sunlight of the lower layer after the plants are planted. The light compensation point of the lower layer of plants cannot be reached, and the plants are difficult to survive; and the two layers of floating beds are only connected by connecting pipes, and the ecological niche that can be reached is shallow. , less water in contact, affecting the treatment effect
