[0002] Ecological water purification usually refers to the process of improving water quality by using the purification capacity of the ecosystem itself, which involves the natural effects of aquatic plants, microbial communities and other aquatic organisms. This method emphasizes the removal of nutrients, heavy metals, organic pollutants and other pollutants from water bodies through the construction or restoration of wetland systems and stream ecological restoration. Ecological water purification technologies include artificial wetlands, ecological floating islands, biological contact oxidation and other forms.

[0003] A water purification dam is a structured water purification facility used to intercept and filter suspended matter, sediment and some pollutants in the water flow to purify the water quality.

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments. Unless otherwise defined, the technical terms or scientific terms used in the present invention should be the common meanings understood by people with ordinary skills in the field to which the present invention belongs. The above-mentioned features or features mentioned in the specific examples mentioned in the present invention can be combined arbitrarily, and these specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0021] Example See also Figures 1 to 10 As shown in the figure, the present invention provides an assembled ecological water purification filter dam, including two mounting beams 1 arranged along the vertical water flow direction, a plurality of support plates 2 are arranged between the two mounting beams 1, and the front and rear ends of the support plate 2 are respectively connected with vertically arranged limit plates 3, and a card slot connected to the mounting beam 1 is formed between the limit plate 3 and the support plate 2. The support plate 2 is connected to the mounting beam 1 through the card slot, which is convenient for the rapid installation and disassembly of the support plate 2, and is convenient for the rapid removal of the water purification filter dam in extreme weather, and rapid drainage, so as to avoid obstruction to the water flow in the river channel and cause disasters such as dam breach. A slow flow mechanism 4 and a water purification mechanism 5 are arranged on the support plate 2 along the water flow direction. After the water flow in the river channel is decelerated by the slow flow mechanism 4, it enters the water purification mechanism 5 for purification and decontamination, effectively removing ammonia nitrogen and organic pollutants in the water body, and enhancing the self-purification ability of the river.

[0022] The slow flow mechanism 4 includes a plurality of swing blades 41 arranged in parallel. A flow velocity meter 42 in the prior art is also provided on the mounting beam 1 located at the front side of the slow flow mechanism 4. The flow velocity meter 42 and the slow flow mechanism 4 are both electrically connected to the controller in the prior art. The flow velocity meter 42 monitors the real-time flow velocity, water level and flow in the river channel, and transmits the data to the controller. The controller controls the swing blade 41 of the slow flow mechanism 4 to rotate after analyzing it through the data processing system in the prior art. By controlling the degree of opening of the swing blade 41, the degree of slowing down of the water flow is controlled. When the water level in the river channel is low, the swing blade 41 is opened a small part to slow down the water flow velocity to a large extent, prolonging the time that the river water stays in the water purification mechanism 5, thereby improving the purification effect of the river water. When the water level in the river channel is high, the swing blade 41 is fully opened to ensure the normal flow velocity of the river water, and prevent the river water from accumulating in the river channel due to the slow flow velocity, causing the water level in the river channel to be higher than the warning water level.

[0023] The slow flow mechanism 4 also includes a protective shell 43, a mounting plate 44, a rotating motor 45, an adjusting rod 46 and a connecting rod 47. The protective shell 43 is arranged on the upper side of the support plate 2. A connecting ear plate 2 48 is provided at the bottom of the protective shell 43. The connecting ear plate 2 48 is provided with a fixing nail 2 49 connected to the support plate 2. The protective shell 43 is firmly connected to the support plate 2 through the cooperation of the fixing nail 2 49 and the connecting ear plate 2 48. In addition, a sealing strip is connected to the end of the protective shell 43 close to the support plate 2 through the existing technology to improve the sealing effect of the protective shell 43.

[0024] The mounting plate 44 is arranged in the protective shell 43, and a plurality of mounting holes 441 are arranged on the mounting plate 44. An adjusting rod 46 is rotatably connected in each mounting hole 441. The bottom of the adjusting rod 46 penetrates the supporting plate 2 and is rotatably connected to the swing leaf 41. A connecting support plate 461 is arranged in the middle of the adjusting rod 46. The plurality of connecting support plates 461 are hinged to the connecting rod 47. The rotating motor 45 is arranged on the upper side of the mounting plate 44, and the output shaft of the rotating motor 45 is connected to the top of one of the adjusting rods 46. A connecting ear plate 3 411 is arranged on the top of the swing leaf 41, and a connecting pillar 1 412 is arranged on the connecting ear plate 3 411. The connecting pillar 1 412 is fixedly connected to the mounting hole 2 462 at the bottom of the adjusting rod 46. A connecting ear plate 413 is arranged at the bottom of the swing leaf 41, and a connecting pillar 2 414 is connected to the lower side of the connecting ear plate 413. The connecting pillar 2 414 is rotatably connected to the bearing seat fixed at the bottom of the river channel. Slant surfaces 415 are provided on both sides of the pendulum blade 41, and the slopes 415 on both sides are arranged parallel to each other. When the slopes 415 of two adjacent pendulum blades 41 close to each other are overlapped and connected, several pendulum blades 41 are connected as a whole, and the slow-flow mechanism 4 is in a closed state. When the slopes 415 of two adjacent pendulum blades 41 close to each other gradually move away from each other, the several pendulum blades 41 change from a state of being connected in parallel to each other to a state of being parallel to each other, and the slow-flow mechanism 4 gradually opens.

[0025] When adjusting the slow flow mechanism 4, the controller is first used to start the rotating motor 45, which drives the adjusting rod 46 connected thereto to rotate, and the adjusting rod 46 pushes the connecting rod 47 to move through the connecting support plate 461, so that the connecting rod 47 pushes other adjusting rods 46 to rotate, thereby realizing the synchronous rotation of multiple adjusting rods 46, and the multiple adjusting rods 46 then respectively drive the swing blades 41 to rotate, thereby realizing the opening and closing of the swing blades 41, and then realizing the adjustment of the opening degree of the slow flow mechanism 4. It is convenient to adjust the slow flow degree according to the water level in the river channel, and improve the purification effect of the river water while ensuring the safety of the river channel.

[0026] The water purification mechanism 5 includes an underwater purification cage 51 and an above-water purification box 52. The middle part of the support plate 2 is a filter screen plate 6 structure. The above-water purification box 52 and the underwater purification cage 51 are respectively arranged on the upper and lower sides of the filter screen plate 6. The bottom of the filter screen plate 6 is symmetrically provided with plug-in grooves 7 on both sides. The top of the underwater purification cage 51 is symmetrically provided with plug-in protrusions 8 on both sides. The plug-in protrusions 8 are plugged and connected in the plug-in grooves 7. The underwater purification cage 51 can be quickly and conveniently installed and disassembled, which is convenient for cleaning, maintenance or replacement of the underwater purification cage 51, providing convenience for the staff.

[0027] A collecting box 9 is provided at the bottom of the underwater purification cage 51 for collecting the sludge deposited after filtering by the underwater purification cage 51. A gravel layer 511, a porous material layer 512 and a biological carrier layer 513 are sequentially provided in the underwater purification cage 51 along the water flow direction. The porous material in the porous material layer 512 is a mixture of quartz sand, activated carbon and ceramsite. The biological carrier layer 513 is loaded with biological agents, which are formed by composite culture of several active microorganisms, including Bacillus, yeast, Bacillus subtilis, Pseudomonas aeruginosa, nitrifying bacteria and denitrifying bacteria.

[0028] After the river water enters the underwater purification cage 51, it is first filtered through the gravel layer 511 to remove large impurities in the river water, and then passes through the porous material layer 512 to remove small particle impurities in the river water. Finally, it enters the biological carrier layer 513. Through the mutual growth and joint action of active bacteria in the biological carrier layer 513, the pollutants in the river water are oxidized and decomposed, and carbon, nitrogen, phosphorus, etc. in the water are removed, thereby achieving ecological purification of the water body.

[0029] A connecting ear plate 521 is provided at the bottom of the water purification box 52, and a fixing nail 522 connected to the support plate 2 is provided on the connecting ear plate 521. The water purification box 52 is surrounded by a grating plate, and the grating plate is coated with an anti-corrosion paint. A filler 523 is provided in the water purification box 52. The filler 523 is a spherical carrier loaded with fertilizer in the prior art. Aquatic plants are planted on the filler 523, and the aquatic plants are emergent plants including calamus and lotus.

[0030] Aquatic plants are planted on the filler 523. The plants of the aquatic plants extend out of the water. The roots of the aquatic plants penetrate the filter screen plate 6 and extend into the underwater purification cage 51. The roots transfer and release oxygen, so that the surrounding environment presents aerobic, anoxic and anaerobic states in turn, so that the microorganisms carried in the biological carrier layer 513 undergo aerobic and anaerobic reactions, thereby achieving biological purification of the river water.

[0031] Specific work process; First, the underwater purification cage 51, the above-water purification box 52 and the slow-flow mechanism 4 are installed on the support plate 2, and then the support plate 2 is successively installed on the mounting beam 1 in a direction perpendicular to the water flow direction. According to the water level in the river channel monitored by the flow rate and velocity meter 42, the swing blade 41 of the slow-flow mechanism 4 is opened to a certain extent to slow down the water flow speed in the river channel. The river water decelerated by the slow-flow mechanism 4 enters the underwater purification cage 51, and is successively purified by the gravel layer 511, the porous material layer 512 and the biological carrier layer 513, thereby improving the purification effect of the river water while ensuring the safety of the river channel.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
