Lift type double positioning modularized submerged plant water purifying device

Abstract

The invention discloses a lift type double positioning modularized submerged plant water purifying device. The lift type double positioning modularized submerged plant water purifying device comprises multiple lift type double positioning modules respectively composed of mattress main bodies and buoyancy systems, wherein each buoyancy system comprises a frame type support, and foam sheets are bound on the frame type supports; each mattress main body comprises a mattress water level regulating frame which is internally provided with a communicating space inside and is composed of an upper rectangular frame, a lower rectangular frame, a latticed connecting pipe and a vertical connecting pipe, a foam supporting plate is fixedly arranged on each lower rectangular frame, multiple holes are formed in each foam supporting plate, and a plastic planting basin planted with submerged plants is embedded in each hole; and an adjustable connecting rope is arranged between each mattress main body and the corresponding buoyancy system. The lift type double positioning modularized submerged plant water purifying device can be used for adjusting positions of the submerged plants in water in a light compensation depth vertical space by virtue of irrigation and water pumping inside each mattress main body and the effect of each adjustable connecting rope, so as to realize change of an ecological niche of the submerged plants along water level, transparency and the like, and the lift type double positioning modularized submerged plant water purifying device has the advantages that multiple aquatic plants can be planted, varieties are rich and the survival rate is high.

Description

technical field [0001] The present invention relates to the ecological reconstruction and recovery technology of natural and artificial rivers and lakes, specifically, to the field of ecological restoration and water quality purification of eutrophication and degradation of aquatic plants, low transparency sediment type, hard bottom type water body , especially relates to a lift-type dual-positioning modular submerged plant water purification 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...

Problems solved by technology

At present, my country's natural water bodies and artificial water bodies are facing problems such as eutrophication and low transparency.

[0005] At present, among the existing patented technologies, what mainly relate to is the ecological floating bed technology, such as: Publication No. CN101007686A, the Chinese patent on August 1, 2007 discloses a "Sewage Biological Treatment Modular Air Floatation Artificial Sunken bed and its production method and purification method", wherein the plants on the floating bed are limited to emergent plants or floating leaf plants that can emerge from the water surface, while ignoring the important role of submerged plants in water body purification

Although some researchers have proposed the concept of a liftable floating bed, as the publication number is CN101356881A, and the publication date is that the Chinese patent on February 4, 2009 discloses a "liftable submerged plant growth bed and its production and application method", The bed body adopts steel bar as support, and the publication number is CN201648116U, and the Chinese patent disclosed on November 24, 2010 discloses a kind of "submerged aquatic plant floating bed", in which the bed body is a hollowed-out metal mesh, metal The bed body made of material is easily corroded and rusted when placed in water for a long time, and the requirements for the buoyancy system are high when floating up, and the cost of the bed body is also high; the publication number is CN201777934U, and the publication date is the Chinese patent publication on March 30, 2011 "A Continuously Adjustable Planting Net Bed for Submerged Plants" and the publication number are CN101356881A, and the publication date is February 4, 2009. In the "Liftable Submerged Plant Growth Bed and Its Making and Application Method" disclosed by China Invention Moso bamboo is used as the buoyancy system. If left for a long time, the moso bamboo will release nutrients into the water after it rots, causing secondary pollution

The publication number is CN202272773, and the publication date is "A Cage Type Ecological Settlement Bed with Adjustable Submerged Water Position" on June 13, 2012. Adjustable submerged plant planting net bed" and the publication number is CN201999795U, and the publication date is "A kind of continuous submerged plant ecological net bed" on October 5, 2011, all of which are fixed piles at the bottom of the water. The stay wire of the pile is used to adjust the position of the bed body underwater, which not only increases the difficulty of construction when installing the bed body on site, increases the cost, but also brings inconvenience to future maintenance
