Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage biological denitrification and dephosphorization device. Background Art

[0002] Biological treatment of sewage is a measure to purify sewage by utilizing the ability of organisms to absorb and degrade pollutants. Biological treatment of sewage is a general term for biological treatment of sewage. It can transform organic matter in sewage into simple inorganic matter with the help of microbial decomposition, so that sewage can be purified. Biological denitrification and phosphorus removal of sewage can utilize the characteristics of bacteria under anaerobic and aerobic conditions to achieve the purpose of denitrification and phosphorus removal, and it is necessary to use biological denitrification and phosphorus removal equipment for sewage;

[0003] After searching, the Chinese patent with the announcement number of CN220317517U discloses a sewage biological denitrification and dephosphorization device, which is provided with a second motor, a storage tank, a stirring shaft, an annular chute and a discharge port. The rotation of the output end of the second motor can drive the stirring shaft to rotate. When the stirring shaft rotates, two discharge ports symmetrically opened at the bottom end of the annular chute will pass through the bottom end of the injection pipe in sequence, so that the medicine stored in the storage tank is injected into the interior of the sewage treatment tank to react with the sewage in the sewage treatment tank. The medicine in the storage tank will be injected into the interior of the sewage treatment tank on time and in quantity. The sewage treatment tank can be stirred by the stirring of the stirring shaft. The sewage inside the tank reacts fully with the reaction agent to improve the efficiency of sewage deammonification and phosphorus removal. The first motor, the screw, the threaded slider and the scraper are provided, and the rotation of the output end of the first motor can drive the screw to rotate. Since the outer side of the screw is provided with a threaded slider, and one end of the threaded slider is connected to one side of the cover plate, when the screw rotates, the threaded slider will slide the cover plate up and down along the installation direction of the screw, and the scraper installed under the stirring shaft will also move synchronously, so as to scrape off the treatment liquid remaining on the inner wall of the sewage treatment tank, so as to avoid reducing the subsequent deammonification and phosphorus removal effect of the device on the sewage.

[0004] In this patent, the temperature of sewage cannot be monitored and adjusted, and a suitable environment cannot be provided for bacteria, which is not conducive to the absorption of nitrogen and phosphorus by the bacterial colony. At the same time, the increased oxygen cannot be fully mixed with the sewage, which is not conducive to improving the efficiency of nitrogen and phosphorus reactant precipitation.

[0006] The technical solution adopted by the utility model is: a sewage biological denitrification and dephosphorization device, comprising:

[0023] The following is combined with Figure 1-4 The utility model is further described.

[0024] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a sewage biological denitrification and phosphorus removal device.

[0025] The specific technical solution includes a gas transmission temperature control component 1;

[0026] like Figure 2-4As shown, the air delivery temperature control component 1 is used to monitor and adjust the temperature of sewage. The air delivery temperature control component 1 includes a fan 101, a top cover 102, an air inlet pipe 103, a heating air delivery pipe 104, a heating wire 105, a gear ring 106, a gear 107 and a motor 108. The fan 101 is fixedly installed on the top of the top cover 102, and the top cover 102 is fixedly installed on the top of the sewage treatment tank 2. The top cover 102 can seal the sewage treatment tank 2 and support the fan 101 and the motor 108. The air inlet pipe 103 is rotatably connected to the air outlet of the fan 101, and the side wall of the air inlet pipe 103 is welded with the heating air delivery pipe 104. 4. The heating wire 105 is fixedly installed in the heating gas pipe 104. A gear ring 106 is fixedly installed on the side wall of the heating gas pipe 104. The gear 107 is meshed with the gear ring 106. The gear 107 is fixedly connected to the output shaft of the motor 108. The motor 108 is fixedly installed on the bottom surface of the top cover 102. A one-way valve 109 is fixedly installed in the port at the top of the air inlet pipe 103. Under anaerobic conditions, the one-way valve 109 can prevent the internal environment of the sewage treatment tank 2 from contacting the external environment. A temperature monitoring sensor 110 is fixedly installed at the bottom of the air inlet pipe 103. An air outlet 111 is opened on the side wall of the heating gas pipe 104.

[0027] When in use, the temperature monitoring sensor 110 can monitor the sewage. When the temperature of the sewage is detected to be lower than the set temperature range suitable for the growth of the bacterial colony, the temperature monitoring sensor 110 transmits the information to the control panel. The control panel controls the heating wire 105 and the motor 108 to start at the same time. The heating wire 105 can heat the side wall of the heating air pipe 104. The side wall of the heating air pipe 104 can heat the contacted sewage. The motor 108 starts to drive the gear 107 to rotate, the gear 107 drives the gear ring 106 to rotate, the gear ring 106 drives the air intake pipe 103 to rotate, and the air intake pipe 103 drives the heating air pipe 104 to rotate, which can accelerate the heated heating air pipe 104 to contact with the sewage, improve the efficiency of sewage heating, and improve the rate of nitrogen and phosphorus absorption by the bacterial colony.

[0028] When the bacterial colonies in the sewage need an aerobic environment, the fan 101 is started to drive the air into the air inlet pipe 103, the air in the air inlet pipe 103 enters the heating air pipe 104, and the air in the heating air pipe 104 is sprayed into the sewage from the air outlet 111, and the motor 108 is started at the same time. According to the step of starting the motor 108 in the previous step, the heating air pipe 104 can be driven to rotate, and the heating air pipe 104 can drive the air outlet 111 to rotate, so that the air sprayed from the air outlet 111 can fully contact with the sewage, and the oxygen in the air can contact with the sewage, which can provide an aerobic environment for the bacterial colonies and improve the efficiency of product precipitation.

[0029] like Figure 1 and Figure 3As shown, the gas transmission temperature control component 1 is fixedly installed on the top of the sewage treatment box 2, and a sealing ring 3 is clamped between the gas transmission temperature control component 1 and the sewage treatment box 2. The sealing ring 3 can seal the connection portion between the sewage treatment box 2 and the top cover 102, and can increase the air tightness of the sewage treatment box 2. A water outlet pipe 4 is fixedly installed at the bottom of the sewage treatment box 2, and a valve 5 is fixedly installed in the water outlet pipe 4. When the sewage treatment is completed, the valve 5 is opened, and water flows from the sewage treatment box 2 into the water outlet pipe 4, and the water in the water outlet pipe 4 flows out after passing through the valve 5. The side wall of the sewage treatment box 2 is installed with a base 6 by welding, and the base 6 can support the sewage treatment box 2 to increase the stability of the sewage treatment box 2.
