Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment equipment, and in particular to an integrated sewage treatment device. Background Art

[0002] The acceleration of urbanization has also led to a sharp increase in the amount of domestic sewage. Domestic sewage contains a large amount of organic matter (such as protein, carbohydrates, fat, etc.), nitrogen (mainly in the form of ammonia nitrogen) and phosphorus and other nutrients. If these substances are discharged directly without treatment, they will cause eutrophication of water bodies, trigger the proliferation of algae, lead to hypoxia in water bodies, and destroy aquatic ecosystems. Lakes and rivers around cities have experienced algal blooms due to the influx of domestic sewage. The lake water has turned green and smelly, and a large number of aquatic organisms such as fish have died. This has continuously increased people's awareness of the importance of environmental protection. The public's demand for clean water resources has prompted the government and enterprises to take measures to treat sewage.

[0072] Working principle: The sewage enters the pre-denitrification tank through the water inlet 2 to preliminarily remove the nitrate nitrogen in the sewage, which reduces the burden for the subsequent deep denitrification treatment. The first water pump 101 is started to pump the sewage in the pre-denitrification tank into the anaerobic tank for further treatment. The anaerobic tank uses the metabolic action of anaerobic microorganisms to decompose the macromolecular organic matter in the sewage into small molecular organic matter, reduce the chemical oxygen demand COD of the sewage, and remove some organic pollutants. Then the second water pump 102 is started to pump the sewage in the anaerobic tank into the anoxic tank for treatment. Under the anoxic condition of the anoxic tank, the denitrifying bacteria use the organic matter in the sewage as a carbon source to reduce the nitrate nitrogen in the reflux liquid of the aerobic tank to nitrogen gas, thereby removing the nitrogen pollutants in the sewage and achieving the purpose of denitrification. The third water pump 103 is convenient for transporting the sewage in the anoxic tank to the aerobic tank. The fourth water pump 1031 is convenient for pumping the reflux liquid of the aerobic tank into the anoxic tank to reduce the nitrate nitrogen therein to nitrogen gas, thereby removing the nitrogen pollutants in the sewage and facilitating the sewage to enter the aerobic tank for treatment;

[0073] Aerobic microorganisms in the aerobic pool completely decompose organic matter in sewage into inorganic matter such as carbon dioxide and water under aerobic conditions, further reducing COD and BOD of sewage and removing most organic pollutants. At this time, the biofilm efficiency can be detected by a dissolved oxygen meter. The aeration speed and aeration swing frequency can be increased according to the biofilm situation to ensure that the aeration oxidation speed can provide a good living environment for aerobic microorganisms and ensure their normal growth, reproduction and metabolic activities.

[0074] After the servo motor 53 is started, the worm 532 can be driven by the servo motor 53 to drive the worm wheel 535 to rotate, and the worm wheel 535 drives the driving disk 52 to rotate through the stabilizing shaft 534, and then the adjusting block 521 on the driving disk 52 rotates and toggles the driving arm 51 to perform swing aeration, and the driving arm 51 drives the torsion disk 502 to rotate, and then the torsion disk 502 drives the first tripod 503 to rotate, and the first tripod 503 drives the second tripod 505 to rotate synchronously through the torsion rotation sealing joint 504, and then the first tripod 503 drives the second tripod 505 to rotate synchronously. The first tripod 503, the second tripod 505 and the rotary seal joint 504 are limited in rotation so that the planetary gear 509 rotates during the swinging process by meshing with the gear ring 501, so that the planetary gear 509 drives the aeration pipe 506 to twist while maintaining the normal operation of aeration. The four-way joint 508 is connected with the external aeration device so that the gas can be connected with the rotary seal joint 504 through the telescopic hose 507 and transported to the aeration pipe 506, and then the aeration pipe 506 is rotated and twisted for aeration, and the film-forming area is increased at the same time.

[0075] At the same time, when the above-mentioned reflux liquid is in the anoxic tank, the main transmission shaft 5371 can drive the first coordinated bevel gear 601 to rotate after rotation, and the first coordinated bevel gear 601 rotates to drive the second coordinated bevel gear 602 and the third coordinated bevel gear 603 to rotate synchronously. When the anaerobic linkage rod 604 rotates, the second linkage bevel gear 612 can be driven to rotate through the first linkage bevel gear 611, and then the anoxic transmission rod 613 can be driven to rotate, and then the anoxic transmission rod 613 drives the third linkage bevel gear 614 to rotate, and the fourth linkage bevel gear 615 is driven to rotate through the third linkage bevel gear 614, and the fourth linkage bevel gear 615 drives the anoxic stirring rod 616 to rotate to coordinately stir the bottom of the anoxic tank, so as to ensure coordination with the twisting frequency of aeration, avoid the reaction speed of the anoxic tank being out of sync with the reaction speed of the aerobic tank, and the large error leads to insufficient biofilm reaction time of the pumped reflux liquid, affecting the sewage treatment effect, and improving the synthesis rate of organic matter;

[0076] The fifth water pump 104 is convenient for pumping the sewage in the aerobic pool to the sedimentation tank for material precipitation. The turbidity sensor 1051 detects whether the turbidity of the clean water discharged by the sixth water pump 105 exceeds the standard. If it exceeds the standard, the mud pump 106 is turned on to extract the sludge. The sedimentation tank separates the mud and water from the sewage after biological treatment, so that the suspended solid substances in the sewage are precipitated to the bottom of the pool to form sludge, and the supernatant is discharged as the treated effluent, so as to achieve the purpose of solid-liquid separation and improve the effluent water quality.

[0077] The sixth water pump 105 is convenient for conveying the clean water after precipitation to the top of the filter bin through the floating block 151 for filtration through the quartz sand filter layer. At this time, the above-mentioned worm 532 rotates and drives the first bevel gear 536 to rotate, so that the first bevel gear 536 drives the second bevel gear 537 to rotate, and the second bevel gear 537 drives the main transmission shaft 5371 to rotate. After the main transmission shaft 5371 rotates, it can drive the first coordinated bevel gear 601 to rotate, and the first coordinated bevel gear 601 rotates to drive the second coordinated bevel gear 602 and the third coordinated bevel gear 603 to rotate synchronously. Since the driving linkage rod 622 is fixed to the third coordinated bevel gear 603, when the driving linkage rod 622 is driven to rotate by the third coordinated bevel gear 603, it can drive the first filter linkage bevel gear 621 to rotate, and the second filter linkage bevel gear 623 is driven to rotate through the first filter linkage bevel gear 621, and then through The filter linkage rod 624 is driven to rotate through the second filter linkage bevel gear 623, and then the filter linkage rod 624 drives the fourth filter linkage bevel gear 626 to rotate through the third filter linkage bevel gear 625 fixed thereto, and then the filter stirring rod 627 is driven to rotate through the fourth filter linkage bevel gear 626. The rotation stability of the filter stirring rod 627 is guaranteed under the rotation limit of the support frame, so that the filter stirring rod 627 rotates to stir the quartz sand to achieve a kneading effect, thereby avoiding the solidification of the quartz sand filter layer and the occurrence of liquid blockage, thereby increasing the service life. The filter bin further removes fine suspended particles, colloidal substances and some soluble organic matter remaining in the sewage, thereby improving the clarity and water quality stability of the effluent, so that the effluent reaches higher water quality standards and meets the requirements of reuse or discharge, and then is discharged from the drain outlet 3.
