Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a water conservancy river pollution ecological restoration device. Background Art

[0002] Ecological restoration of water conservancy river pollution refers to restoring and improving the ecological functions and water quality of polluted waters, protecting water resources, and promoting the sustainable development of ecosystems through a series of engineering and ecological means. River pollution is mainly caused by various pollution sources such as industrial wastewater, agricultural pollutants, and domestic sewage, which often leads to problems such as water quality deterioration, ecological imbalance, and biodiversity decline.

[0003] In the current field of sewage treatment technology, sewage treatment equipment presents diversified characteristics, including a sewage treatment aeration tank disclosed in the publication number CN117602731B, which can clean foam and scum during aeration. However, in the process of foam formation, oil and organic matter are common sewage pollutants, especially in industrial wastewater and catering wastewater, which often contain high grease and some foam-prone substances (such as proteins, sugars, etc.). In the process of microbial metabolism, these substances may further promote the generation of foam. Specifically, when river wastewater mixed with oil and organic matter enters the aerobic tank, the grease will form fine oil droplets. These oil droplets are easy to adhere to the surface of bubbles, resulting in the generation of foam. Therefore, simply eliminating foam cannot fundamentally solve the cause of foam generation, because the formation of foam is usually the result of the combined effect of the presence of grease and organic matter and the bubble attachment phenomenon in the process of microbial metabolism. In order to effectively avoid the impact of foam on the aerobic tank and solve this problem, in addition to cleaning the foam, measures need to be taken to reduce the concentration of grease and foam-prone substances in the water.

[0044] The working principle of the present invention is as follows:

[0045] First, aerate the wastewater and transport it to the aerobic pool 1: place the aeration assembly 2 at the center of the bottom wall of the aerobic pool 1, and the sewage in the aerobic pool 1 will enter the water inlet pipe 211 through the joint 210, and squeeze the air in the water inlet pipe 211. The air in the water inlet pipe 211 will enter the connecting telescopic pipe 207 through the clamp 212, driving the second connecting ring 205 to slide down and the telescopic sleeve 204 to slide and shrink. In this way, when the aerator 201 is turned on for aeration, the lower spray The nozzle 202 will aerate at the inner bottom of the aerobic tank 1, while the sliding and descending second connecting ring 205 and the upper nozzle 206 will aerate at the inner top of the aerobic tank 1, respectively aerating the lower layer and the middle and upper layers of the sewage to increase the aeration effect. It should be noted that when aeration is performed in the center of the aerobic tank 1, the bubbles generated will push the foam generated by the scum such as oil and organic matter on the surface of the sewage to the edge of the aerobic tank 1, and the air supply pipe 208 will transport the external air to the open aerator 201;

[0046] Second, collect the scum such as oil and organic matter produced by the foam on the surface of the sewage: through the setting of the water inlet pipe 305, the wastewater in the aerobic pool 1 will slowly enter the water reservoir 302 through the connecting box 304 and the connecting pipe 303, and accumulate in the water reservoir 302. As the wastewater continues to accumulate, the weight of the wastewater will drive the lifting plate 306 to descend in the water reservoir 302 and the external box 301, and break through the resistance of the telescopic top block 309, so that the lifting plate 306 and the arc surface of the upper end of the telescopic top block 309 slide downward, and after the telescopic top block 309 is squeezed, it will compress the second spring 310 in the sliding box 308 and slide, the descending lifting plate 306 will compress the first spring 307, and the wastewater will pass through The water pipe 311 is discharged into the filter water box 501. The inner diameter of the water pipe 311 is larger than the inner diameter of the water inlet pipe 305, so the waste water will be quickly discharged into the filter water box 501 through the water pipe 311. After the waste water accumulated on the upper end of the lifting plate 306 is completely discharged, the compressed first spring 307 will push the lifting plate 306 upward to contact the inclined surface of the lower end surface of the telescopic top block 309 and slide to the top of the telescopic top block 309. The lifting plate 306 will drive the connecting plate 312 to lift together during the process of being driven to intermittently lift. The lifting connecting plate 312 will drive the annular water storage tank 411 to lift together. The annular water storage tank 411 will generate a flow gap with the inner wall of the aerobic tank 1 during the descent process (see attached Figure 7 As shown in the figure, at the same time, the foam and other scum pushed to the inner edge of the aerobic tank 1 during aeration will flow into the descending annular water storage tank 411 along with part of the sewage through the flow gap. The foam, scum and sewage entering the annular water storage tank 411 will enter the sewage box 401 through the collar 412 and the first water inlet 410, and accumulate at the upper end of the lower pressure plate 408. The continuously accumulated foam, scum and sewage will drive the lower pressure plate 408 to slide down in the sewage box 401. When the lower pressure plate 408 descends, it will drive the slide The rod 406 slides down in the sliding telescopic tube 405 and compresses the third spring 407. When the lower pressing plate 408 is continuously descending, it will be adsorbed on the upper end of the sliding telescopic tube 405 and staggered with the blocking block 409 to form a flow gap. The foam, scum and sewage accumulated on the upper end of the lower pressing plate 408 will flow to the lower layer of the sewage box 401 through the flow gap. The oil, scum and organic matter in the sewage that cause the foam will be filtered by the filter cotton 403, and the filtered sewage will flow to the bottom layer of the sewage box 401.

[0047] Third, backflow sewage: the sewage that has been filtered and entered the bottom layer of the sewage box 401 will be discharged into the external box 301 through the water pipe, and then discharged into the filter box 501 through the water pipe 311. When the slide rod 406 is driven to slide down in the sliding telescopic tube 405, the air in the sliding telescopic tube 405 will be transported to the fixed box 507 through the air pipe, increasing the air pressure in the fixed box 507. The air with increased air pressure in the fixed box 507 will drive the slide plate 508 to slide in the fixed box 507, and the sliding slide plate 508 will drive the bracket 510 As the magnetic strip 511 approaches the armature 512, the armature 512 connected to the external power source interacts with the magnetic field generated by the magnetic strip 511 to form a torque, which causes the armature 512 to rotate. The rotating armature 512 drives the auger teeth 503 to rotate together, and the wastewater entering the water filter box 501 enters the water supply pipe 502 through the second water inlet 505. As the auger teeth 503 rotate, the wastewater flows upward in the water supply pipe 502, and finally is discharged into the aerobic pool 1 above the aerobic pool 1 through the outlet pipe 504;

[0048] Aeration is performed in the aerobic tank 1 through the aeration component 2, which provides sufficient oxygen for the microorganisms in the aerobic tank. At the same time, the bubbles generated by aeration push the foam and scum on the surface of the sewage to flow to the edge of the aerobic tank 1;

[0049] Part of the sewage is first discharged into the water storage tank 302 and the external box 301 to drive the lifting plate 306 to move up and down. During the lifting and lowering process of the lifting plate 306, the annular water storage tank 411 is driven to move up and down intermittently through the connecting plate 312. The foam and scum flowing to the edge of the aerobic tank 1 will flow into the annular water storage tank 411 during the descent of the annular water storage tank 411, and flow into the sewage box 401, driving the lower pressing plate 408 to move up and down, and the oil, organic matter and scum that generate foam are thoroughly filtered through the filter cotton 403;

[0050] The filtered sewage can enter the water filter box 501 through the water pipe 311 together with the sewage entering the external box 301, and finally be discharged into the aerobic pool 1 again;

[0051] During the period of sewage treatment in the aerobic tank 1, the above steps can repeatedly filter and treat the oil, scum and organic matter on the surface of the sewage.
