Description

Technical Field

[0002] Aerated biological filter is a new type of sewage treatment technology. It was born in the late 20th century and was first developed by the French OTV company. It combines the advantages of the biofilm method and the activated sludge method. By loading high specific surface area granular fillers in the bioreactor, it provides a carrier for the growth of microbial membranes and uses a combination of biochemical reactions and physical filtration to treat sewage. Aerated biological filters are suitable for removing pollutants such as COD, BOD, ammonia nitrogen, SS, TN, etc., and are particularly suitable for occasions that require efficient treatment and limited floor space.

[0003] In addition, during the sewage treatment process in the aerated biological filter, it is necessary to add chemicals therein. The added chemicals can help remove suspended matter and organic matter in the sewage. For example, polyaluminum chloride (PAC) and polyacrylamide (PAM) can effectively remove suspended matter and colloidal substances and improve the treatment efficiency. However, during the treatment process, it is not convenient to filter the solid impurities during sewage treatment, which may affect the sewage treatment efficiency.

[0040] Embodiment 3

[0041] See also Figure 1-8 On the basis of the first embodiment, the stirring mechanism 4 further comprises a supporting frame 41, the supporting frame 41 is fixedly connected to the top left end of the aeration treatment tank 1, the top of the supporting frame 41 is fixedly connected to the bottom end of the material box 31, the top left end of the supporting frame 41 is fixedly connected to a second motor 42, the bottom end of the second motor 42 is fixedly connected to an electric shaft 43, the upper surface of the electric shaft 43 is fixedly connected to a transmission wheel 45, the surface of the transmission wheel 45 is transmission-connected to a transmission belt 46, the lower surface of the electric shaft 43 is fixedly connected to a transmission belt 46, and the lower surface of the electric shaft 43 is fixedly connected to an agitator 44.

[0042] Furthermore, a circular hole is opened inside the support frame 41, and there are four electric shafts 43. The surfaces of the four electric shafts 43 match the circular holes. When the second motor 42 drives the electric shaft 43 to rotate, it drives the transmission wheel 45 and the transmission belt 46 to rotate, and then drives all the electric shafts 43 to rotate, and can drive the agitator 44 to rotate at the same time, so as to quickly and evenly mix the medicine and sewage, thereby improving the sewage treatment efficiency.

[0043] In actual operation, when the device is used, when the device is used for sewage treatment, two side chambers on the left and right sides of the aeration treatment tank 1 are provided inside. Water outlets are provided on both sides of the aeration treatment tank 1 and connected to water pipes. Sewage enters the left chamber of the aeration treatment tank 1 from the left side of the aeration treatment tank 1 for treatment, and during the treatment, agents are added to improve the sewage treatment effect. When adding agents, the agents are placed inside the material box 31, and the first motor 33 drives the electric rod 34 to rotate, thereby driving the conical material block 36 to change the gap with the bottom material block 37 when rotating, thereby facilitating the addition of agents to the left chamber in the aeration treatment tank 1.

[0044] In the process of sewage aeration treatment, corresponding solid impurities will be generated and need to be filtered. In this case, a multi-stage filtering mechanism 2 is set in the right chamber of the aeration treatment tank 1, and each filter 26 is used for corresponding filtering to reduce impurities and achieve the purpose of water purification. In addition, in this process, when there are too many impurities on the surface of the filter 26 and they need to be processed, the motor pole 23 drives the hollow bar 24 to rotate, and drives the T-shaped round block 29 and the cross bar 27 to move up and down under the limit of the slider 291 inside the aeration treatment tank 1, and then drives the cleaning brush 28 to move up and down to clean the surface of the filter 26, so as to clean the solid impurities on the surface of the filter 26, thereby ensuring the filtering effect of sewage treatment, thereby ensuring the quality of sewage treatment;

[0045] In addition, when adding chemicals, in order to ensure that the added chemicals are mixed evenly, the chemicals can be stirred at this time. The second motor 42 drives the electric shaft 43 to rotate, which drives the transmission wheel 45 and the transmission belt 46 to rotate, and then drives all the electric shafts 43 to rotate, which can also drive the agitator 44 to rotate at the same time, thereby quickly and evenly mixing the chemicals and sewage, thereby improving the sewage treatment efficiency.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
