Description

Technical Field

[0001] The invention relates to the technical field of water quality restoration equipment, in particular to a composite ecological filter bed for water quality ecological restoration. Background Art

[0002] Composite ecological filter bed is a technology used for water ecological restoration. It effectively removes pollutants such as organic matter, nitrogen, phosphorus, etc. from water bodies by simulating the purification mechanism of natural wetlands, while providing a suitable habitat to promote the recovery and diversity of aquatic organisms. Ecological filter beds usually contain porous media, plants and microorganisms, which together form a multifunctional ecosystem to achieve multiple physical, chemical and biological purification processes.

[0003] However, most of the existing ecological filter beds utilize the natural flow of water bodies, allowing the water bodies to pass through ecological green plants and absorb nutrients in the water, such as nitrogen and phosphorus, through the roots of the ecological green plants, and then intercept and adsorb suspended matter in the water through the adsorption fillers in the filter beds. Since the natural flow speed of the water body is relatively slow and the speed of passing through the adsorption fillers is slow, it is easy to cause floating objects on the water surface to gather and accumulate around the filter bed, which will affect the growth of ecological green plants over time, resulting in the ecological green plants' ability to purify water bodies becoming increasingly poor.

[0027] Example

[0028] like Figure 1 and Figure 2 As shown, a composite ecological filter bed for water quality ecological restoration includes: an ecological green plant planting cylinder 1, a floating body 2, a water inlet cylinder 3, a filter cylinder 5 and a negative pressure cylinder 4.

A plurality of water inlet pipes 31 are provided near the top of the water inlet tube 3. Water enters the inner cavity 33 of the water inlet tube 3 from the water inlet pipes 31. An adsorption block 13 is embedded at the bottom of the water inlet tube 3. The adsorption block 13 is provided with a plurality of adsorption channels extending into the interior and interconnected with each other. Floating objects in the water are purified through the adsorption channels. One end of the adsorption block 13 is connected to the bottom of the ecological green plant planting tube 1. The root system and rhizomes of the ecological green plants cooperate with the adsorption channels to improve the purification effect on the water. The inner cavity 33 of the water inlet tube 3 is connected to the side of the adsorption block 13. , used to introduce water into the adsorption channel in the adsorption block 13 for purification; one end of the filter cartridge 5 is connected to the bottom of the water inlet cartridge 3, and the cover surface of the cartridge mouth of the filter cartridge 5 covers the cover surface of the bottom of the adsorption block 13, so that the water purified by the adsorption block 13 can completely enter the filter cartridge 5; the negative pressure cartridge 4 is sleeved on the outside of the water inlet cartridge 3, and is used to form a negative pressure in the cartridge, thereby forming a vortex in the cartridge, so as to achieve the goal of sucking the water around the ecological filter bed into the inner cavity 33 of the water inlet cartridge 3 through the water inlet pipe 31, and accelerating it through the adsorption channel of the adsorption block 13, and finally passing through the filter cartridge 5, and then discharged through the water pump 6, one end of the negative pressure cartridge 4 is connected to the bottom of the water inlet cartridge 3, and a water outlet 41 is opened at the bottom of the negative pressure cartridge 4, and a water pump 6 is arranged on the water outlet 41.

[0029] like Figure 2As shown, the ecological green plant planting tube 1 includes: a fixed frame 14 and a plurality of planting tubes 11. The fixed frame 14 is a plate structure, and its edge is connected to the inner wall of the ecological green plant planting tube 1. A plurality of channels are opened on the fixed frame 14; the plurality of planting tubes 11 are correspondingly arranged in the channels on the fixed frame 14, and each planting tube 11 is used to plant ecological green plants. The ecological green plants can be divided into multiple groups, and different filtering structures can be formed through different arrangements and combinations to improve the water purification effect. Different ornamental patterns can also be formed through different arrangements and combinations to improve the ornamental effect. In this embodiment, since the water inlet pipes 31 on the water inlet tube 3 are distributed on the peripheral side of the water inlet tube 3, the water enters the water inlet tube 3 from multiple circumferential positions of the water inlet tube 3. Therefore, as shown in FIG. Figure 4 As shown, this embodiment provides multiple groups of planting tubes 11 arranged in a circular array, and the formed arrangement structure can purify water entering from multiple directions.

[0030] like Figure 2 As shown, it also includes: a closed top plate 132 and a plurality of root extension tubes 12, the closed top plate 132 is used to close the top surface of the adsorption block 13; the plurality of root extension tubes 12 are all tubes with closed sides, the plurality of root extension tubes 12 correspond one to one with the plurality of planting tubes 11, and one end of the root extension tube 12 is connected to the bottom of the corresponding planting tube 11, and the other end passes through the closed top plate 132 and is connected to the interior of the adsorption block 13, the roots of the green plants in the planting tube 11 grow in the root extension tube 12, and enter the adsorption block 13 through the diversion of the root extension tube 12, and are covered with the adsorption channels of the adsorption block 13, when water enters the adsorption block 13 and the water level moves up, the water body can only enter the root extension tube 12 through the action of the closed top plate 132, and the upward moving water body is purified by the roots and rhizomes grown in the root extension tube 12.

[0031] like Figure 2 and Figure 3 As shown, a filter screen is fitted on the side of the adsorption block 13, and the filter screen is called the filter side wall 131 of the adsorption block 13 to prevent large floating objects from directly blocking the adsorption channels of the adsorption block 13 and affecting the circulation of water in the overall adsorption channels.

[0032] In some embodiments, in order to further clean the filter side wall 131 and prevent plastic bags or other floating objects with a large coverage area from clogging the filter side wall 131, the water inlet cylinder 3 also includes a shell 32, which is mounted on the outside of the water inlet cylinder 3, and a filter side wall cleaning component 7 is provided at the position corresponding to each water inlet pipe 31 in the shell 32.

[0033] like Figure 2 and Figure 3As shown, in order to reduce the investment in electrical equipment and make full use of the water flow impact of the water inlet pipe 31, a plurality of notches are opened on the inner wall of the water inlet cylinder 3, and the plurality of notches correspond to the positions of the plurality of filter side wall cleaning components 7.

The sealing layer 75 is a folded sealing sheet connected between the plate surface of the scraper 74 and the notch to seal the notch. The water flowing in from the water inlet pipe 31 falls on the scraper 74. One end of the scraper 74 sinks due to the impact of the water flow, and the other end rotates the gear 71 by rotating the gear shaft. The meshing rack 72 is continuously pulled and vibrated up and down by the upper and lower springs 73, so that the gear 71 rotates back and forth, so that one end of the scraper 74 scrapes back and forth on the filter side wall 131, thereby scraping away floating objects such as plastic bags that are easily adhered to the filter side wall 131, ensuring that the water can smoothly enter the adsorption channel in the adsorption block 13.

[0034] like Figure 3 As shown, the filtering side wall 131 is arc-shaped, and the center of the circle coincides with the central axis of the gear shaft of the gear 71 , so that one end of the scraper 74 can always be closely attached to the outer side of the filtering side wall 131 .
