[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] The embodiment proposed in the present application is: a lake water ecological restoration filter bed device, including a floating bed box, the floating bed box has a specification of 2m in length, 1.5m in width, and 1.3m in height, and a stuffing box 1, a biological purification box 2, and a water collection tank 5 are installed inside.
[0028] like Figure 1 The stuffing box 1 is located on the left side of the inner wall of the floating bed box, and its specifications are 0.6m long, 1m wide and 1.3m high. A water inlet hole is provided on the lower side of the stuffing box 1, so that the lake water from the outside can enter the interior of the stuffing box 1 through the water inlet 11, and 4 layers of fillers are laid inside the stuffing box 1. The fillers are set as pebbles, ceramsite, activated carbon and fine sand from bottom to top, so that the flow aperture of the water entering the stuffing box 1 becomes smaller from bottom to top, so that the water entering the stuffing box 1 can be gradually filtered and treated, and the top of the stuffing box 1 is used to plant aquatic plants iris and foxtail algae.
[0029] Furthermore, filter nets are respectively provided between the four layers of different fillers inside the stuffing box 1. There are three groups of filter nets, which are fixed inside the stuffing box 1. At the same time, the aperture of each layer of filter net is smaller than the diameter of the filler located on its upper side to prevent the different fillers from mixing and reducing the filtering effect.
[0030] In a further embodiment, Figure 1 and Figure 2 The biological purification box 2 is installed on the right side of the stuffing box 1, and its specifications are 1m long, 1.5m wide and 1.1m high. At the same time, the interval between the biological purification box 2 and the stuffing box 1 is 0.1m, and the total height of the stuffing inside the stuffing box 1 is 0.1m lower than the top of the box body, so that the water filtered by the stuffing box 1 can flow out from its upper side.
[0031] A guide plate 4 is fixed on the upper left side of the biological purification box 2, and the guide plate 4 is butted against the upper right side of the stuffing box 1. The guide plate 4 is located 0.1 m below the top of the stuffing box 1, and the guide plate 4 is inclined at 45° with respect to the purification box 2, so that the water flowing out from the upper side of the stuffing box 1 is introduced into the biological purification box 2 through the guide plate 4.
[0032] Furthermore, multiple groups of biofilm plates 3 are provided on the left and right sides of the purification box 2, and the biofilm plates 3 on both sides are staggered. Each group of biofilm plates 3 is inclined at 30° to the inner wall of the purification box 2 to facilitate the diversion of water entering the purification box 2.
[0033] Specifically, the biofilm plate 3 also includes a biofilm and a bracket. The biofilm covers the upper surface of the bracket. The bracket is connected to the purification box 2 and is installed according to specific circumstances. Since a large number of microorganisms are attached to the biofilm, the basic environment for the survival of microorganisms is transformed from the original gas and liquid two-phase to gas, liquid and solid three-phase. This change creates a richer form of existence for microorganisms, forming a more complex ecosystem, which is more conducive to removing organic pollutants in water bodies. At the same time, an opening is provided at the end of each group of brackets, and water is discharged through the opening to facilitate the transmission of water through different biofilm plates 3.
[0034] A water outlet 21 is provided at the lower right end of the purification box 2, and the purification box 2 is connected to the water collecting box 5 through the water outlet 21, so that the water in the clean water tank can enter the interior of the water collecting box 5 through the water outlet 21, wherein the water collecting box 5 is located on the right side of the floating bed box, and its specifications are 0.3m long, 1.5m wide and 1.3m high.
[0035] Furthermore, a water intake mechanism is provided on the upper side of the water collecting tank 5, through which the water inside the water collecting tank 5 is extracted and sprayed into the lake. The sprinkled water droplets carry a large amount of oxygen in the air into the lake, which can increase the oxygen content of the water body and provide good growth conditions for animals, plants and microorganisms in the water body.
[0036] Specifically, the water intake mechanism includes a water pump 6, a water outlet pipe 61 and a nozzle 62. The water pump 6 is installed inside the upper end of the water collecting tank 5. The water outlet pipe 61 is connected to the water outlet end of the water pump 6. The nozzle 62 is set at the water outlet 21 of the water outlet pipe 61. After the water pump 6 is started, the water inside the water collecting tank 5 is extracted through the water inlet end of the water pump 6, and the water is sprayed out by the nozzle 62. In order to maintain better water intake from the water collecting tank 5, a water inlet pipe can be installed at the water inlet end of the water pump 6, and the water inlet 11 of the water inlet pipe is close to the inner end bottom of the water collection tank. The connection between the water inlet pipe and the water outlet pipe 61 and the water pump 6 can adopt the existing pipeline connection method.
[0037] Working principle: Lake water enters the stuffing box 1 from the water inlet 11. After being purified and filtered by layers of stuffing, the water enters the biological purification box 2 through the guide plate 4. The water flows from the top bio-membrane plate 3 to the next bio-membrane plate 3, and then enters the water collecting tank 5 from the water outlet 21. Finally, the water inside the water collecting tank 5 is extracted by the water pump 6, and the purified lake water is exported from the water collecting tank 5 through the outlet pipe 61 and the nozzle 62, and then sprayed into the lake.
