Description

Technical Field

[0001] This invention relates to the field of river water body restoration technology, and in particular to a device and method for river ecological environment protection and restoration. Background Technology

[0002] River ecological restoration refers to the use of ecosystem principles and various methods to repair damaged aquatic ecosystems, restore healthy aquatic ecosystems, repair and strengthen the main functions of aquatic ecosystems, and enable ecosystems to achieve a virtuous cycle of overall coordination, self-sustaining, and self-succession. Wastewater discharge from daily life into surrounding rivers is a common source of black and odorous water pollution. Excessive nitrogen and phosphorus in the water also leads to eutrophication, and the accumulation of pollutants exacerbates river pollution. When large amounts of pollutants flow into rivers, they deplete dissolved oxygen, creating an anoxic state. This severely affects the water's reoxygenation capacity, causing the river to become an anaerobic environment where large amounts of pollutants ferment and produce substances that cause blackening and odor, further worsening the transformation of urban rivers into black and odorous water bodies. Conventional microbial remediation techniques are easily washed away by water flow when treating black and odorous rivers, leading to a decrease in the number of microorganisms and thus a decline in treatment effectiveness. Therefore, there is an urgent need for a river water restoration device that can adjust the number of fixed microorganisms and perform targeted restoration of river water. Summary of the Invention

[0003] The purpose of this invention is to provide a device and method for river ecological environment protection and restoration. The fixing frame of the microbial fixing unit controls the extension length of the first fixing rod and the second fixing rod, thereby controlling the number and range of action of the microbial carrier fixing frame.

The airbag unit has several airbag bases on both sides of the airbag base one. The tops of the airbag base one and the airbag base two are connected by a connecting frame. The airbag base one has a drive protective cover in the center. The drive motor inside the drive protective cover is connected to the drive rod through a transmission component. The drive rod is connected to the aeration component of the aeration unit. The fixing frame of the microbial fixation unit is connected to the extension rod of the connecting frame.

Both the fixed seat and the fixed seat are provided with a rotating through hole on the upper part. The rotating through hole is hinged to the drive rod. The positioning rod connected to the edge of the airbag base is connected to the bottom of the river.

[0008] Preferably, the drive protective cover is located between the fixed bases, the drive motor inside the drive protective cover is connected to the horizontal bevel gear of the transmission assembly, the horizontal bevel gear meshes with the vertical bevel gear sleeved on the drive rod, and the side wall of the drive protective cover is provided with a drive through hole that is hinged to the drive rod.

[0009] Preferably, extension rods are connected to the four corners of the connecting frame, and the ends of the extension rods are connected to the side of the fixed frame away from the adjusting motor. The waterproof cover of the adjusting motor is connected to the fixed frame.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. Unless otherwise defined, the technical or scientific terms used in this invention should be understood in their ordinary sense by those skilled in the art. The features mentioned above or in the specific examples mentioned in this invention can be combined arbitrarily, and these specific embodiments are only used to illustrate the invention and are not intended to limit the scope of the invention.

[0019] Example 1 like Figure 1 As shown, this invention provides a river ecological environment protection and restoration device, including an aeration unit 1, a microbial fixation unit 2, and an airbag unit 3. Several airbag bases 32 are provided on both sides of the airbag base 31 of the airbag unit 3, and the tops of the airbag base 31 and the airbag bases 32 are connected by a connecting frame 33. A drive protective cover 16 is provided in the center of the airbag base 31, and a drive motor 13 inside the drive protective cover 16 is connected to a drive rod 12 through a transmission assembly. The drive rod 12 is connected to the aeration assembly 11 of the aeration unit 1, and the fixing frame 21 of the microbial fixation unit 2 is connected to the extension rod 34 of the connecting frame 33.

[0020] Aeration unit 1 oxygenates the river water and assists the microorganisms in microbial immobilization unit 2 in decomposing pollutants in the river water. Airbag unit 3 ensures that drive motor 13 and regulating motor 28 are always above the river water surface. Drive motor 13 controls the operation of aeration component 11, and regulating motor 28 controls the extension length of the first fixing rod 25 and the second fixing rod 26, thereby controlling the number of microbial immobilization carriers and the range of action of microorganisms in the river water.

[0021] like Figure 2 As shown, the rotating circular plate 111 of the aeration assembly 11 is connected to the drive rod 12 at its center. The edge of the rotating circular plate 111 is evenly provided with several water-stirring perforated plates 112, each with a V-shaped cross-section. The back of the water-stirring perforated plates 112 is connected to a connecting bent rod 113, and the back of the connecting bent rod 113 is connected to a reinforcing plate 114. Both the connecting bent rod 113 and the reinforcing plate 114 are connected to the edge of the rotating circular plate 111.

[0022] The drive rod 12 drives the rotating circular plate 111 to rotate, which in turn drives the agitator plate 112 to move. The agitator plates 112 at different positions come into contact with the river water in sequence, injecting oxygen into the river water. The shape of the agitator plate 112 reduces the resistance to water entry. At the same time, the water passage holes in the agitator plate 112 increase the water-air contact area, promote the breakup of air bubbles, and help oxygen dissolve in the water more quickly.

[0023] The connecting part of the connecting rod 113 is close to the rotating circular plate 111. Both ends of the bent portion of the connecting rod 113 are connected to the connecting part and the agitator plate 112, respectively. The inclination angle of the connecting part is the same as the inclination angle of the agitator plate 112, while the inclination angle of the bent part is smaller than that of the agitator plate 112, thus allowing the end of the bent part to connect with the agitator plate 112. The reinforcing plate 114 increases the load-bearing capacity of the connecting rod 113 during the contact between the agitator plate 112 and water, extending the service life of the aeration assembly 11.

[0024] like Figure 5 and Figure 6As shown, an adjusting gear 22 is hinged inside the fixing frame 21 of the microbial fixation unit 2. The adjusting gear 22 is connected to an adjusting motor 28 outside the fixing frame 21. The upper and lower sides of the adjusting gear 22 mesh with a first adjusting rack 23 and a second adjusting rack 24 inside the fixing frame 21, respectively. The first adjusting rack 23 is located at the bottom of the first fixing rod 25, and the second adjusting rack 24 is located at the top of the second fixing rod 26. Both the first fixing rod 25 and the second fixing rod 26 have fixing through holes 27 on their side walls, which are connected to the microbial carrier fixing frame 29.

[0025] The adjusting shaft of the adjusting gear 22 is hinged to the side wall of the fixed frame 21. The adjusting shaft is connected to the adjusting motor 28, which controls the rotation of the adjusting gear 22, thereby driving the first adjusting rack 23 and the second adjusting rack 24, which mesh with it, to move closer or further apart. The first adjusting rack 23 controls the movement of the first fixed rod 25, and the second adjusting rack 24 controls the movement of the second fixed rod 26, thereby adjusting the distance between the first fixed rod 25 and the second fixed rod 26. This allows for the control and adjustment of the position and number of the fixing through holes 27 outside the fixed frame 21, and ultimately, the adjustment of the position and number of the microbial carrier fixing frame 29.

[0026] The airbag base 31 has a fixing seat 36 on both sides, and the airbag base 32 has a fixing seat 37 on the side away from the airbag base 31. Both the fixing seat 36 and the fixing seat 37 have a rotating through hole on their upper parts. The rotating through hole is hinged to the drive rod 12, and the positioning rod 35 connected to the edge of the airbag base 31 is connected to the bottom of the river.

[0027] The number of airbag bases 32 on both sides of the first airbag base 31 is the same. An aeration component 11 is provided between the first airbag base 31 and each second airbag base 32. An aeration component 11 is also provided on the outside of each second airbag base 32. The symmetrical arrangement of the structure ensures the balance of the remediation device. The positioning rod 35 is set to fix the remediation device in a certain position after being connected to the bottom of the river.

[0028] The drive protective cover 16 is located between the fixed base 1 and 36. The drive motor 13 inside the drive protective cover 16 is connected to the horizontal bevel gear 14 of the transmission assembly. The horizontal bevel gear 14 meshes with the vertical bevel gear 15 sleeved on the drive rod 12. The side wall of the drive protective cover 16 is provided with a drive through hole that is hinged to the drive rod 12.

[0029] like Figure 3 and Figure 4 As shown, the drive motor 13 drives the horizontal bevel gear 14 to rotate, which in turn drives the vertical bevel gear 15 to rotate, thereby driving the drive rod 12 to rotate, thus enabling the aeration assembly 11 to operate. The drive protective cover 16 is provided to prevent water from affecting the operation of the drive motor 13.

[0030] Extension rods 34 are connected to the four corners of the connecting frame 33. The ends of the extension rods 34 are connected to the side of the fixing frame 21 away from the regulating motor 28. The waterproof cover of the regulating motor 28 is connected to the fixing frame 21. The connecting frame 33 is connected to the first airbag base 31 and the second airbag base 32, thereby ensuring the smooth operation of the aeration component 11. The extension rods 34 are designed to place the microbial carrier fixing frame 29 near the aeration component 11, and the water stirring plate 112 does not come into contact with the microbial fixing carrier.

[0031] The first fixing rod 25 is slidably connected to the first limiting guide rail at the bottom of the fixing frame 21, and the second fixing rod 26 is slidably connected to the second limiting guide rail at the top of the fixing frame 21. The first limiting guide rail limits the movement angle of the first fixing rod 25, and the second limiting guide rail limits the movement angle of the second fixing rod 26.

[0032] The microbial carrier holder 29 has a fixing ring at its top, which is detachably connected to the fixing through hole 27. The microbial carrier holder 29 has a microbial carrier in its lower part. The first fixing rod 25 and the second fixing rod 26 each have 7 fixing through holes 27, which are connected to the microbial carrier holder 29. The number of fixing through holes 27 extending out of the holder 21 is selected according to the requirements, and the microbial carrier holder 29 is connected to the fixing through holes 27.

[0033] Example 2 The above-mentioned method for river ecological environment protection and restoration includes the following steps: S1. The user places the repair device in the river by boat and connects the positioning rod 35 to the bottom of the river, thereby fixing the repair device in the river.

[0034] S2. Connect the fixing frame 21 of the microbial fixation unit 2 to the extension rod 34, turn on the adjusting motor 28, and control the extension length of the first fixing rod 25 and the second fixing rod 26 according to the usage requirements. Then connect the microbial carrier fixing frame 29 to the fixing through hole 27. The microbial composite bacteria fixed on the microbial fixation carrier improve the water quality in the river. The microorganisms are fixed on the microbial fixation carrier, which improves the restoration effect of the microbial composite bacteria on the river water.

[0035] The microbial complex includes one or more of the following: *Pseudomonas putida*, lactic acid bacteria, *Arthrobacter*, *Bacillus subtilis*, and nitrifying bacteria. *Pseudomonas putida* degrades organic matter in the water and participates in nitrogen conversion. Lactic acid bacteria produce lactic acid through sugar fermentation, which can regulate the pH of the river water to some extent, helping to maintain a suitable acid-base environment during river water treatment and indirectly promoting the activity of other microorganisms. *Arthrobacter* has a high adsorption capacity for heavy metals, reducing heavy metal ions in the river water. Among *Bacillus subtilis* and nitrifying bacteria, *Bacillus subtilis* first rapidly degrades organic matter, reducing COD and improving the biodegradability of the river water. Simultaneously, it promotes the sedimentation of suspended particles through bioflocculation, improving water transparency and competitively inhibiting harmful microorganisms. Nitrifying bacteria then efficiently convert ammonia nitrogen, completing the oxidation process from ammonia nitrogen to nitrite and then to nitrate, laying the foundation for biological denitrification and effectively purifying the water.

[0036] S3. Start the drive motor 13. The transmission assembly drives the drive shaft and rotating disc 111 to rotate. The agitator plate 112 contacts the water surface, injecting air into the river water. The oxygen entering the river water provides oxygen for the work of the microbial complex bacteria, improving the degradation and removal efficiency of pollutants such as organic matter, and repairing and purifying the river water.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
