[0025] The filtration tank 10 includes a bed body arranged underground, a micro-ecological filtration bed arranged in the bed body, and a lighting and ventilation mechanism arranged in the bed body. The lighting and ventilation mechanism is used to provide light and air circulation;

[0026] The filtration water path includes a water storage tank 20 and a recycled water tank 30 arranged below the filtration tank 10, and a circulation pipeline connecting the filtration tank 10, the water storage tank 20, and the recycled water tank 30. The circulation pipeline includes a water inlet pipeline 40 arranged at the inlet end of the water storage tank 20, a water delivery pipeline connecting between the upper surface of the water storage tank 20 and the micro-ecological filtration bed, and a drainage pipeline communicating between the lower surface of the micro-ecological filtration bed and the recycled water tank 30. The water delivery pipeline is used to deliver the water to be filtered in the water storage tank 20 into the filtration tank 10, and the drainage pipeline is used to deliver the filtered water to be filtered into the recycled water tank 30. The recycled water tank 30 is also provided with a water extraction pipeline 24 for delivering the filtered water to be filtered to the outside for use. Among them, the water inlet pipeline 40 is used to deliver rainwater or sewage into the water storage tank 20 for filtration. The water storage tank 20 is usually made of reinforced concrete structure, and in special cases, it can also be customized with fiberglass material. If it is a reinforced concrete water tank, the micro-ecological filter bed can be built above the water tank. If it is made of fiberglass material, the micro-ecological filter bed is still built underground, but it cannot be built directly above the water tank.

[0027] In this embodiment, the micro-ecological filtration bed includes a micro-ecological filter bed matrix 16 arranged in the bed body and hygrophytic emergent plants 17 arranged on the micro-ecological filter bed matrix 16. Among them, the main core of the micro-ecological filter bed water treatment process relies on the combined action of microorganisms and plants. The micro-ecological filter bed is completely built underground, and the height from the surface of the micro-ecological filter bed matrix 16 to the ground is controlled between 1.5 meters and 2 meters, leaving enough growth space for plants. In the case of being completely buried, the temperature is relatively constant. On the one hand, it can ensure the activity of microorganisms, and on the other hand, it can also shorten the withering period of plants, and even may not wither, maximizing the treatment efficiency. This completely buried micro-ecological filter bed device is particularly suitable for the northern regions with low temperatures. The micro-ecological filter bed matrix 16 is the main matrix material in the micro-ecological filter bed. Microorganisms grow on the matrix 16, and hygrophytic emergent plants 17 are also planted on the surface of the matrix 16. The micro-ecological filter bed matrix 16 and hygrophytic emergent plants 17 are both existing technologies and will not be elaborated here.

[0028] In this embodiment, the water delivery pipeline includes a water delivery pump 21 arranged at the bottom of the water storage tank 20, a connecting pipe 22 connecting the water delivery pump 21 and the bed body, and a water sprinkling pipe 24 arranged on the upper surface of the micro-ecological filter bed matrix 16. A number of water sprinkling holes are arranged at intervals on the water sprinkling pipe 24. The water to be filtered is evenly sprinkled on the surface of the micro-ecological filter bed matrix 16 through the water sprinkling holes, improving the filtration efficiency.

[0029] In this embodiment, the drainage pipeline includes a water suction pipe 31 provided at the bottom of the microecological filter bed matrix 16 and a drain pipe connected to the reused water tank 30. A drainage check valve 32 is provided on the drain pipe. By providing the drainage check valve 32, it is convenient to drain the filtered water into the reused water tank 30 and prevent the water in the reused water tank 30 from flowing back into the microecological filter bed matrix 16.

[0030] In this embodiment, the lighting and ventilation mechanism includes a plant growth lamp 12 provided in the bed body and a ventilation structure. The ventilation structure includes an exhaust fan 15 provided in the bed body, an exhaust pipe 14 connected to the exhaust fan 15, and a ventilation pipe 13 communicating in the bed body. The parts of the exhaust pipe 14 and the ventilation pipe 13 extending out of the ground are higher than the ground and are in an inverted L shape. The lighting and ventilation structures are configured according to the area of the microecological filter bed. The specific configuration ratio is as follows: For a 100-square-meter microecological filter bed, 4 DN100 ventilation pipes 13 are required. 4 exhaust pipes 14 can be provided corresponding to the ventilation pipes 13. Among them, the lower ends of the 4 ventilation pipes 13 extend to the surface of the microecological filter bed matrix 16 and 4 exhaust fans 15 with a diameter of DN100 are installed. The materials of the exhaust pipe 14 and the ventilation pipe 13 are stainless steel, and the height above the ground is 0.5 to 1 meter, ensuring that the ventilation pipes are not easily broken and preventing rainwater on the ground from flowing back into the underground space. The exhaust fan 15 is set to an automatic operation mode and runs for 10 minutes every 2 hours to exhaust the air at the bottom layer to the ground. At the same time, the fresh air on the ground is transported to the underground space through another 4 exhaust pipes.

[0031] In this embodiment, the 24-way water suction pipe includes a water pump 33 provided at the bottom of the reused water tank 30 and a water suction pipe 24 connected to the water pump 33. The other end of the water suction pipe 24 is externally connected to a water-using device. By providing the 24-way water suction pipe, the filtered water is pumped out for use, improving the utilization rate of water resources.

[0032] In this embodiment, there are 22-way connecting pipes formed between the water storage tank 20 and the reused water tank 30. An overflow check valve 25 is provided on the 22-way connecting pipe. The overflow check valve 25 is used to limit the water flowing from the water storage tank 20 into the reused water tank 30. The treated water is discharged into the reused water tank 30 regularly and quantitatively every day. After the reused water tank 30 is full, the excess water will be discharged into the water storage tank 20 through the overflow check valve 25.

[0033] In this embodiment, well channels communicating with the ground are provided on both the water storage tank 20 and the reused water tank 30, and a manhole cover 23 is provided at the outlet end of the well channel. By providing the well channels, it is convenient to collect rainwater or use the filtered water resources through channels other than the 24-way water suction pipe.

[0034] In this embodiment, a light-transmitting skylight 11 is provided on the top of the bed. The size of the light-transmitting skylight 11 is 20cm*40cm, and the light-transmitting skylight 11 is equipped with tempered glass of corresponding size and thickness of 1cm, and is sealed around. In order to protect the tempered glass, a stainless steel protective grille is installed above the tempered glass.

[0035] The present application sets the filter pool and the filter waterway underground, and provides light and air to the microecological filter bed through a lighting and ventilation mechanism, so as to provide a good growth environment for the microecological filter bed. At the same time, it avoids occupying the ground space, saves the ground space to the maximum extent, and does not affect the original planning and appearance of the ground space. The filter waterway is used to collect filtered water to transport it to the filter pool for filtration, and the filtered water is collected for use at any time when water is needed, thereby improving the utilization rate of water resources.

[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
