Embodiment 1
[0033] (1) Plant filter pool construction
[0034] Choose a flat ground on the river bank, the height is about 1 meter from the river surface, and use cement to build a rectangular pool with a height of 1 meter, a width of 1 meter, and a length of 4 meters. A waterproof layer is made around the interior, and marble bricks are inlaid on the exterior. According to the structure Schematic diagram of laying water pipes and placing water pumps.
[0035] (2) Adsorption matrix layer and soil layer filling
[0036] The filling sequence of the adsorption layer is as follows: firstly place the sandstone layer 5 to be 10cm, then place the inorganic adsorption material layer 4 to be 20cm, the adsorption material is composed of a mixture of perlite and activated carbon, and the weight ratio is 9.5:0.5; then place the fiber content to 70%. The moss peat layer 3 is 20cm; then the inorganic adsorption material 2 composed of perlite and activated carbon is placed to be 30cm; finally the 20cm ...
Embodiment 2
[0040] (1) Plant filter pool construction
[0041] Choose a flat ground on the river bank, the height is about 1 meter above the river surface, and use cement to build a rectangular pool with a height of 1.2 meters, a width of 2 meters, and a length of 10 meters. The interior is surrounded by a waterproof layer, and the exterior is inlaid with brick red tiles. Structural diagram laying water pipes and installing water pumps.
[0042] (2) Adsorption matrix layer and soil layer filling
[0043] The filling sequence of the adsorption layer is as follows: first place the sand layer 5 with a thickness of 10 cm, then place the inorganic adsorption material layer 4 with a thickness of 30 cm, the adsorption material is composed of a mixture of vermiculite and activated carbon, and the weight ratio is 9.5:0.5; The moss peat layer 3 is 30cm; then the inorganic adsorption material 2 composed of perlite and activated carbon is placed to be 30cm; the 20cm soil layer 1 is placed at last. ...
Embodiment 3
[0047] (1) Plant filter pool construction
[0048] Choose a flat ground on the river bank, the height is about 1 meter above the river surface, and use cement to build a rectangular pool with a height of 1.3 meters, a width of 1 meter, and a length of 20 meters. Schematic diagram of laying water pipes and placing water pumps.
[0049] (2) Adsorption matrix layer and soil layer filling
[0050] The filling sequence of the adsorption layer is: first place the sandstone layer 5 to be 10cm; then place the inorganic adsorption material layer 4 to be 30cm, the adsorption material is composed of perlite and vermiculite mixed in any proportion, and then mixed with activated carbon, the weight ratio is 9.5: 0.5; then placing the moss peat layer 3 with a fiber content of 70% is 30cm; then placing the inorganic adsorption material 2 composed of perlite, vermiculite and activated carbon is 30cm; finally placing the 30cm soil layer 1. After the layers are lightly compacted, marigolds and...
