Description

Technical Field

[0001] The utility model relates to the technical field of filter tanks, in particular to an intensive sulfur autotrophic denitrification filter tank with a suspended matter interception function. Background Art

[0002] The intensive sulfur autotrophic denitrification filter with suspended solids interception function is an efficient and environmentally friendly sewage treatment technology. It combines the two major functions of suspended solids interception and sulfur autotrophic denitrification to achieve intensive and efficient sewage treatment. When sewage enters the filter, it is first intercepted by the filter layer, and impurities such as suspended solids and particulate matter in the sewage are intercepted on the filter surface, thereby purifying the water quality. In the filter layer, the attached autotrophic denitrifying bacteria use reduced sulfur (such as elemental sulfur, thiosulfate, etc.) as an electron donor and nitrate as an electron acceptor to carry out autotrophic denitrification, reducing nitrate to nitrogen gas, thereby achieving a denitrification effect.

[0003] Since the filter element is fixed in the water, adjusting its position requires shutting down the machine and disassembling related components, which is a complicated and time-consuming operation. This not only affects the operating efficiency of the filter, but may also have an adverse effect on the stability of the sewage treatment system. To this end, we propose an intensive sulfur autotrophic denitrification filter with suspended solids interception function. Utility Model Content

[0004] The purpose of the utility model is to provide an intensive sulfur autotrophic denitrification filter with a suspended matter interception function, so as to solve the problems raised by the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an intensive sulfur autotrophic denitrification filter tank with a suspended matter interception function, comprising a filter tank, the filter tank is slidingly connected to a limit frame, the bottom end of the limit frame is sealed with a composite filter material component, one end of the limit frame is installed with a drain pipe, the drain pipe is through-connected to the limit frame, the limit frame can be height-adjusted by a lifting assembly, the lifting assembly includes a lifting structure and a driving structure, and the bottom end of the filter tank inner cavity is provided with an aeration component.

[0006] Preferably, the lifting structure includes a gear condition, a gear part and a limit seat. A group of the gear conditions are installed on the top of each end of the limit frame. The gear condition is engaged with the gear part. The gear part is rotatably connected to the limit seat. The limit seat is connected to the filter tank, and the gear part is connected to the drive structure.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model places the composite filter material into water and uses the aeration element to allow compressed air to pass into the filter tank. When the compressed air is pressed into the filter tank, the bubbles will pass through the composite filter material during the rising process. These bubbles will not only scrub the impurities on the lower surface of the filter material, but also form disturbances inside the composite filter material, which helps to loosen and disperse the impurities attached to the filter material particles. Although the bubbles mainly act on the inside of the composite filter material, their vibration and disturbance effects will also affect the upper surface of the composite filter material, making it easier for the impurities on the upper surface to be washed away by the subsequent water flow. The drain pipe can be connected to the suction device to clean the impurities. Extraction is carried out. When the concentration of suspended solids or pollutants in the sewage is high, the sewage is passed into the container formed by the limit frame and the filter tank, and filtered using the composite filter material. The filtered water enters the filter tank for subsequent treatment. When biodegradation or denitrification treatment is required, the composite filter material needs to be exposed to the air and the lifting component is used to lift the composite filter material out of the water in the filter tank so that microorganisms can use the oxygen in the air for metabolic activities, thereby improving the treatment efficiency. Compared with the existing technology, the position of the composite filter material can be adjusted, and there is no need to stop the machine and disassemble related components during adjustment. The operation is simple and time-saving, which improves the operating efficiency of the filter tank.

[0012] 2. Each set of rack conditions in the utility model is composed of two sets of racks, which are respectively installed on both sides of the limit frame. The gear parts include two sets of gears meshing with the racks and a rotating rod. The two sets of gears are installed on the outside of the two ends of the rotating rod. By starting the motor, a set of gear parts connected thereto can be driven to rotate, which drives a set of pulleys to rotate. Through the transmission of the belt, another set of pulleys is driven to rotate, so that the other set of gear parts rotates. The rotation of the two sets of gear parts drives the gear conditions to move, and the limit frame can be mobilized to rise and fall, and the height of the composite filter material can be adjusted. The sliding connection between the limit frame and the limit rod can play a limiting role, keep the meshing of the gear conditions and the gear parts, do not affect their connection, and also maintain the stability of the limit frame lifting.

[0013] 3. The second aeration pipe of the utility model penetrates the filter tank and can be connected to the air supply assembly in the prior art. The first aeration pipe is a rectangular structural member, and multiple groups of third aeration pipes are arranged equidistantly inside it. Gas can flow out from the through hole, which helps to maintain the uniformity of the air supply. The bubbles generated by aeration are used to clean the composite filter material and then rinse it.

Through the transmission of the belt 9, another set of pulleys 8 is driven to rotate, so that another set of gear parts 6 rotates. The rotation of the two sets of gear parts 6 drives the gear condition 5 to move, and the limit frame can be adjusted to move up and down. The height of the composite filter material 3 can be adjusted.
