Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly relates to a domestic sewage treatment device based on intelligent feedback. Background Art

[0002] Domestic sewage is the sewage discharged in the daily life of residents, mainly from residential buildings and public buildings, such as residences, government agencies, schools, hospitals, stores, public places, and the toilets of industrial enterprises, etc. The pollutants contained in domestic sewage are mainly organic matters (such as proteins, carbohydrates, fats, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and enteric infectious viruses, etc.). The organic matters existing in domestic sewage are extremely unstable and easily rot to produce a foul smell. If bacteria and pathogens multiply in large numbers using the organic matters in domestic sewage as nutrients, it can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge.

[0003] Sewage treatment refers to the process of treating wastewater containing various pollutants through a series of physical, chemical, biological and other treatment processes to remove or reduce the content of pollutants therein, and finally reach a certain treatment standard to achieve the safe discharge or recycling of sewage. The filter ponds of existing sewage treatment devices usually require manual removal of filter residues, which is time-consuming and laborious and not conducive to use. Summary of the Invention

[0004] The present invention aims to provide a domestic sewage treatment device based on intelligent feedback to solve the problem that the filter ponds of existing sewage treatment devices usually require manual removal of filter residues, which is time-consuming and laborious and not conducive to use.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The basic technical solution provided by the present invention is: a domestic sewage treatment device based on intelligent feedback, including a filtration tank, a first sealed tank, a second sealed tank, an aeration tank, a sedimentation tank, a purification tank and a water inlet pipe. The filtration tank is fixedly connected with a water guide trough, and a filter plate is arranged between the filtration tank and the water guide trough. The first sealed tank is provided with a water inlet, and the water guide trough is located above the water inlet. The first sealed tank is connected to the second sealed tank through a first water guide pipe, and a first water pump is arranged on the first water guide pipe. The second sealed tank is connected to the aeration tank through a second water guide pipe, and a second water pump is arranged on the second water guide pipe. The second sealed tank is provided with a third return pipe leading to the first sealed tank, and a sixth water pump is arranged on the third return pipe. The aeration tank is connected to the sedimentation tank through a third water guide pipe, and a third water pump is arranged on the third water guide pipe. The sedimentation tank is connected to the purification tank through a fourth water guide pipe, and a fourth solenoid valve is arranged on the fourth water guide pipe. The fourth water guide pipe is connected with an ozone generator. The water inlet pipe is fixedly connected with a first spray pipe and a second spray pipe respectively through a tee. A first solenoid valve and a second solenoid valve are arranged on the first spray pipe and the second spray pipe respectively. The first spray pipe and the second spray pipe are both fixedly connected with spray heads. The filtration tank is slidably connected with a bottom plate. The two spray heads are respectively used for flushing the bottom plate and the sedimentation tank. The bottom plate is fixedly connected with a connecting rod. The filtration tank is fixedly connected with a support frame. The support frame is fixedly connected with an electric telescopic rod. The electric telescopic rod is rotationally connected with the connecting rod. The connecting rod is fixedly connected with an eccentric rod. The support frame is provided with a sliding groove, and the eccentric rod is slidably connected with the sliding groove. The purification tank is fixedly connected with a drain pipe. The drain pipe is fixedly connected with a return pipe and a water outlet respectively through a tee. A fifth solenoid valve and a sixth solenoid valve are arranged on the return pipe and the water outlet respectively. A fifth water pump is arranged on the return pipe. The return pipe leads to the first sealed tank.

[0007] Principle of the basic technical solution: Sewage is initially filtered through a filter tank to separate larger impurities in the sewage. Anaerobic microorganisms in the first sealed tank anaerobically decompose most of the organic matter in the sewage, and at the same time convert the difficult-to-decompose and non-dissolved organic matter in the sewage into easily decomposable dissolved organic matter. The second sealed tank is used for denitrification to remove nitrogen elements in the water. At the same time, a part of the mixed liquid can be driven back to the first sealed tank through the third reflux pipe and the sixth water pump to improve the denitrification effect. Microorganisms in the aeration tank decompose organic matter to produce carbon dioxide and water, and at the same time cultivate nitrifying bacteria to decompose ammonia nitrogen in the sewage into nitrate nitrogen. The sedimentation tank is used to separate mud and water. Part of the sludge is refluxed to the anaerobic reactor to accelerate the anaerobic reaction in the anaerobic tank, and part of the sludge is discharged to remove phosphorus. The supernatant is discharged into the purification tank, and the water is purified through the purification tank to remove small particulate matter and suspended matter in the water; when there are more impurities in the filter tank, the electric telescopic rod is contracted to drive the bottom plate to move downward, so that it is separated from the filter tank. At the same time, the bottom plate drives the eccentric rod to slide along the chute through the connecting rod. During the sliding process of the eccentric rod, it will shift in the horizontal direction. Therefore, the eccentric rod drives the connecting rod to rotate, and then drives the bottom plate to rotate to keep a certain inclination, so as to facilitate the separation of impurities from the bottom plate. Through the flushing of the nozzle, the impurities are more easily separated from the bottom plate.

[0008] The beneficial effects of the basic technical solution are as follows: By operating the electric telescopic rod, the automatic dumping of impurities can be realized. The nozzle is of a hemispherical structure with a wide spraying range. By spraying water through the nozzle, the bottom plate can be cleaned, thus realizing the automatic cleaning work of the bottom plate, and the cleaning effect is good, solving the problem that the filter tank of the existing sewage treatment device usually requires manual salvage of filter residues, which is time-consuming and laborious and not conducive to use; Through the settings of the first sealed tank, the second sealed tank and the aeration tank, effective denitrification and phosphorus removal operations are carried out on the sewage. Through the purification of the sedimentation tank and the purification tank, the treatment effect of water is further improved, and the resource utilization rate and treatment effect of the whole device are improved.

[0009] Preferably, a second stirring rod is rotatably connected to the sedimentation tank, and a second motor is fixedly connected to the sedimentation tank. The rotating shaft of the second stirring rod is fixedly connected to the output shaft of the second motor.

[0010] Through the above settings, the second motor drives the second stirring rod to mix the sediment at the bottom of the sedimentation tank with the cleaning water, which is convenient for treating the sediment accumulated at the bottom and preventing equipment blockage.

[0011] Preferably, the sedimentation tank is connected to the first sealed tank through a first reflux pipe, and a fourth water pump is provided on the first reflux pipe.

[0012] Through the above settings, the fourth water pump transports a part of the sludge or sediment cleaning mixture in the sedimentation tank to the first sealed tank through the reflux pipe, which is beneficial to the anaerobic reaction in the first sealed tank and realizes the circulating treatment of the cleaning liquid.

[0013] Preferably, the purification tank is fixedly connected to a drain pipe, and a water quality detector is provided on the drain pipe. The drain pipe is fixedly connected to a second return pipe and a water outlet through a tee. A fifth solenoid valve and a sixth solenoid valve are respectively provided on the second return pipe and the water outlet. A fifth water pump is provided on the second return pipe, and the second return pipe leads to the first sealed tank.

[0014] With the above settings, the water quality detector is used to detect whether the water quality of the water discharged from the purification tank meets the standard. If it meets the standard, it is discharged through the water outlet. If it does not meet the standard, it is discharged into the first sealed tank through the second return pipe under the action of the fifth water pump for secondary treatment, thus ensuring the effectiveness of sewage treatment.

[0015] Preferably, a first stirring rod is rotatably connected to the aeration tank, and a first motor is fixedly connected to the aeration tank. The rotating shaft of the first stirring rod is fixedly connected to the output shaft of the first motor.

[0016] With the above settings, the first motor is used to drive the first stirring rod, thereby increasing the air exchange rate of the water in the aeration tank and improving the rate of aerobic reaction of the water in the aeration tank. At the same time, the first stirring rod runs for a long time to form a biological film, which can improve the sewage treatment efficiency.

[0017] An exhaust pipe and a pressure sensor are provided in both the first sealed tank and the second sealed tank, and a third solenoid valve is provided on the exhaust pipe.

[0018] With the above settings, the internal pressure of the first sealed tank and the second sealed tank is detected by the pressure sensor, and the gas generated in the first sealed tank and the second sealed tank is discharged through the exhaust pipe, which can be used as fuel or used to produce chemical raw materials. The on-off of the exhaust pipe is controlled by the third solenoid valve.

[0020] With the above settings, the control module uses Pump 1 to drain the water treated in Sealed Pond 1 into Sealed Pond 2, uses Pump 2 to drain the water treated in Sealed Pond 2 into the aeration tank, and uses Pump 3 to drain the water treated in the aeration tank into the sedimentation tank. After the water has settled in the sedimentation tank for a certain period of time, the control module opens Solenoid Valve 4 to drain the water into the purification tank, and ozone is generated by the ozone generator and mixed with the water to achieve the purpose of sterilization; the water coming out of the purification tank through the drain pipe is detected by the water quality detector, and the water quality detector transmits the detection result to the control module. Based on this, the control module controls the opening of either Solenoid Valve 5 or Solenoid Valve 6, so as to re-treat the water or directly discharge it. If the standard is not met, Solenoid Valve 5 is opened, and the water is transferred to Sealed Pond 1 through Pump 5 for re-treatment. If the standard is met, Solenoid Valve 6 is opened for direct discharge; two groups of air pressure sensors transmit the detected gas pressure to the control module, and based on this, the control module controls the on-off of the two groups of Solenoid Valve 3 respectively, which is conducive to controlling the pressure in Sealed Pond 1 and Sealed Pond 2; the control module can control the operation of the electric telescopic rod at regular intervals, and at the same time open Solenoid Valve 2 to make the spray head on it spray water, so as to clean the filter residue on the bottom plate regularly; when the sedimentation tank needs to be cleaned, Solenoid Valve 1 is opened through the control module to make the spray head on it spray water, and at the same time Motor 2 is turned on to make Stirring Rod 2 rotate, and Pump 4 is used to transfer water to Sealed Pond 1 through Return Pipe 1 to achieve the purpose of cleaning the sedimentation tank; through the overall control of the control module, it is conducive to the automatic operation of this device, which not only improves the effectiveness of sewage treatment, but also reduces the work pressure of the staff and is worthy of promotion.

The baffles prevent the filter residue on the bottom plate from detaching from both sides of the bottom plate, thus facilitating the collection of the filter residue. The setting of the sealing plate improves the sealing performance between the bottom plate and the filter tank, thereby reducing the probability of sewage seepage.

[0023] Preferably, the purification tank is filled with a gravel layer, a coarse sand layer and an activated carbon layer.

[0024] With the above settings, the gravel layer is used to filter large particulate impurities, the coarse sand layer is used to filter small particulate impurities, and the activated carbon is used to adsorb impurities such as organic matter, pigments and odors in the water.

[0025] Preferably, both Sealed Pond 1 and Sealed Pond 2 are provided with covers, and the covers are fixedly connected with handles.

[0026] With the above settings, opening the cover through the handle facilitates the staff to disinfect the interiors of Sealed Pond 1 and Sealed Pond 2. Brief Description of the Drawings

[0037] The specific implementation process is as follows:

[0038] When using the present invention, an external power supply is used as the energy driver of the device. First, sewage is introduced into the filtration tank 1, where it passes through the filter plate 103 to remove larger solid impurities. The filtered water flows through the water guide groove 104 and enters the first sealed tank 2 through the water inlet 201, where anaerobic reaction occurs inside, decomposing most of the organic matter in the sewage anaerobically. At the same time, the difficult-to-decompose and non-dissolved organic matter in the sewage is transformed into easily decomposable dissolved organic matter. The sewage treated in the first sealed tank 2 enters the second sealed tank 3 through the water guide pipe 202 under the action of the first water pump 203, and nitrogen in the water is removed by denitrification in the second sealed tank 3. At the same time, a part of the mixed liquid can be refluxed to the first sealed tank 2 through the third reflux pipe 303 and the sixth water pump 304 to improve the denitrification effect. The water treated in the second sealed tank 3 enters the aeration tank 4 through the second water guide pipe 301. Microorganisms in the aeration tank 4 decompose organic matter to produce carbon dioxide and water, and nitrifying bacteria convert ammonia nitrogen in the sewage into nitrate nitrogen. The rotation of the first stirring rod 403 is driven by the first motor 404 to increase its conversion rate. The mixed liquid treated in the aeration tank 4 enters the sedimentation tank 5 through the third water guide pipe 401. The sedimentation tank 5 separates mud and water. Part of the sludge is refluxed to the first sealed tank 2 through the first reflux pipe 503, thus accelerating the anaerobic reaction in the first sealed tank 2. At the same time, a tee is provided in the first reflux pipe 503 to guide the excess sludge to a reasonable position, and phosphorus is removed by sludge discharge. When the sedimentation tank 5 needs to be cleaned, the rotation of the second stirring rod 505 is driven by the second motor 506, and at the same time, the first solenoid valve 702 is opened to activate the nozzle 705 located above the sedimentation tank 5 to fully clean the sedimentation tank 5. The supernatant in the sedimentation tank 5 is discharged into the clean water tank through the fourth water guide pipe 501. The fourth water guide pipe 501 is connected to an ozone generator 507, and the ozone generated by the ozone generator 507 is used to sterilize the water, further improving the water purification effect. Finally, the water is purified in the purification tank 6 to remove small particulate matter, suspended matter and peculiar smell in the water. The water purified in the purification tank 6 is discharged through the drain pipe 601. The drain pipe 601 is connected to a water quality detector 607. Through water quality detection, it is determined whether the water quality meets the standard. If it meets the standard, the sixth solenoid valve 606 is opened to discharge it. If it does not meet the standard, the fifth solenoid valve 603 and the fifth water pump 604 are opened, and it is discharged into the first sealed tank 2 through the second reflux pipe 602 for re-treatment, thus improving the effectiveness of sewage treatment, ensuring the cleanliness of sewage treatment, and being beneficial for use;When there are many impurities in the filter pool 1, the electric telescopic rod 1016 is retracted to drive the bottom plate 101 to move downward, so that it can be separated from the filter pool 1. At the same time, the bottom plate 101 drives the eccentric rod 1014 to slide along the slide groove 1015 through the connecting rod 1013. The eccentric rod 1014 will deviate to the horizontal direction during the sliding process. Therefore, the eccentric rod 1014 drives the connecting rod 1013 to rotate, and then drives the bottom plate 101 to rotate to keep it at a certain inclination, so that it is easy for impurities to separate from the bottom plate 101. By opening the electromagnetic valve 2 704, the water flow passes through the nozzle 705 to flush the bottom plate 101, so that the impurities can be more easily separated from the bottom plate 101; each component can be started regularly through the control module 8 and the program, and remote control can be realized through software association and program setting to achieve the effect of intelligent control. ;
