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...
