Problems solved by technology

Various water purification schemes have been proposed accordingly, but there are almost no separate structures involving water purification and greening by setting plants at the same time in the schemes near bank slopes or bridges.
At present, there are also many projects that use plant growth to prevent river bank erosion. At this time, plants are mainly fixed on the plant growth mat structure, and greening is carried out directly on the river bank. This method is complicated to operate and has high requirements on plants. At the same time, the water purification effect is not good.
There are also some projects that only use concrete structures for slope protection without plant growth, which damages the natural beauty

Embodiment 1

[0028] 1) Flat pad production

[0029] Palm fibers (100 denier, 30mm in length) are interlaced with needles to form a flat mat with a basis weight of 900g / m2, a thickness of 50mm, a width of 500mm, and a length of 500mm.

[0030] 2) Green water purification structure

[0031] A groove part with a width of 1000mm and a depth of 50cm is made of porous concrete with a length of 200cm. The groove part is filled with a rock layer with an average particle size of 150mm and a thickness of 35cm. Then, the flat mat and activated carbon made by 1) are arranged: Artificial sintered culture soil = 1:3 water purification material 5cm thickness. Finally, a flat pad (base weight 900g / m2, thickness 50mm, width 50mm) with holes (interval 40mm) is laid, and fixed water edge plants are inserted at a certain interval, such as figure 2 Said constitutes a green water quality purification structure. Such a structure has a good water purification effect, and the growing plants feel natural....

Embodiment 2

[0033] 1) Cylindrical mats are used

[0034] Palm fiber (100 denier, length 30mm) is interwoven into a net with needles to form a flat mat with a basis weight of 270g / m2, a thickness of 15mm, a width of 1000mm, and a length of 1800mm.

[0035] 2) Structure of water purification material

[0036] Mix 330g of activated carbon (average particle size 3mm, specific surface area 1000m2 / g) and artificial sintered culture soil (average particle size 5mm) 1000g. Cylindrical bags (50mm in diameter and 1000mm in length after filling) are made of nylon non-woven fabric as water purification materials.

[0037] 3) Seed pad modulation

[0038] Adhere the water edge plant seeds in the middle of 2 sheets of paper to prepare a seed pad with a thickness of 1mm, a width of 1000mm and a length of 1800mm.

[0039] 4) Cylindrical water purification layer structure

[0040] Use the mat made in 1), arrange a cylindrical bag on the upper end, roll the water purification material and the m...

Abstract

The water quality purification method for greening rivers and lakes uses a groove structure made of porous concrete as the main body. Plant mats and water purification materials are arranged inside the groove structure. Aquatic plants are cultivated on the plant mats. Water treatment microorganisms are applied in the grooves. The groove structure is made of porous concrete. The tank, vegetation mat and water purification layer simultaneously serve as carriers of microorganisms for water treatment that can add both aerobic and inter-aerobic types. Lay rubble at the bottom of the groove structure, and then place a flat mat of plant fiber, a water purification layer, and a flat mat of plant fiber on the rubble layer in sequence. The cross-section of this structure is U-shaped. The invention has the advantages of simple structure, convenient construction, low cost, etc. It is installed on both sides of rivers, lakes, landscape pools or bridge sides to achieve the two major purposes of water purification and greening at the same time.

Description

technical field [0001] The invention relates to a greening water purification method and device, a groove-shaped porous concrete structure with greening function and water purification function, belonging to the field of water environment treatment. Background technique [0002] In recent years, water pollution in rivers, lakes, and landscape pools has become increasingly serious, and unpleasant odors and other unpleasant sensations have seriously affected the lives of surrounding residents. Various water purification schemes have been proposed accordingly, but there is almost no separate structure involving water purification and greening by setting plants at the same time in the scheme near the bank slope or bridge. At present, there are also many projects that use plant growth to prevent river bank erosion. At this time, plants are mainly fixed on the plant growth mat structure, and greening is carried out directly on the river bank. This method is complicated to oper...
