Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to an integrated sewage treatment box. Background Art

[0002] The main source of container washing water is the washing water generated when cleaning the inside of the container after the ship docks and unloads. Therefore, the container washing water needs to be treated. Usually, an integrated sewage treatment tank is used to treat the washing water. The integrated cleaning tank will be equipped with a screen well, a grease trap, a regulating tank, an anaerobic tank, an anoxic tank, an aerobic tank, an MBR membrane tank and a disinfection tank to treat the sewage.

[0003] The announcement number is CN218435204U, a light urban sewage filtration and purification system, belonging to the field of sewage treatment, including an integrated sewage treatment tank, each inspection port on the upper part of the integrated sewage treatment tank is covered with a top cover, and a lifting device is fixedly installed on one side surface of the integrated sewage treatment tank. Through the provided lifting device, the lifting-controlled lifting box can facilitate the transfer work when the filter assembly is replaced, eliminating the tedious replacement procedure of manually taking the filter assembly and climbing the integrated sewage treatment tank. Through the provided lifting box, when the filter assembly is placed in the lifting box, the fixed half shell and the movable half shell are adaptively extended under the action of the elastic component, which can not only expand the placement capacity of the lifting box as needed, but also the adaptive contraction of the fixed half shell and the movable half shell can keep the inserted filter assembly clamped and positioned, thereby preventing the filter assembly from shaking during the lifting process.

[0004] This device can transport the filter assembly through the action of the movable half shell and the fixed half shell. However, when using the MBR membrane, the height of the MBR membrane is usually to meet the purification needs. Therefore, the overall height of the MBR membrane and the mounting bracket will reach 1.8-2 meters. Therefore, after the MBR membrane is placed between the movable half shell and the fixed half shell and transported to the ground, the movable half shell is restricted by the return spring and the baffle, and the MBR membrane can only be lifted vertically upward from between the movable half shell and the fixed half shell. When lifting it, due to the height of the MBR membrane, there is a risk of tipping over of the staff, causing the MBR membrane to press on the staff and cause harm to the staff.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figure 1-5An integrated sewage treatment tank shown in the figure includes a tank body 1, a maintenance cover 2 for taking out items is provided at the top of the tank body 1, a ladder 3 for people to climb is provided on one side of the tank body 1, a clamping mechanism for carrying items is provided on one side of the tank body 1, and a driving device 16 for moving the clamping mechanism is provided on the side of the clamping mechanism close to the tank body 1. The clamping mechanism includes a clamping assembly, an opening and closing assembly and a symmetrically arranged locking assembly. The clamping assembly includes a movable clamp 4 and a movable clamp 5. The movable clamp 4 is arranged on the side of the movable clamp 5 away from the tank body 1. The opening and closing assembly includes an opening and closing door 8, which is arranged at the top of the movable clamp 4, and one side of the opening and closing door 8 is hinged to one side of the movable clamp 4.

[0023] Specifically, a linkage plate 15 for connecting to the driving device 16 is fixedly connected to the side of the movable clamp 5 close to the box body 1 , and a limiting groove 17 for limiting the rotation of the linkage plate 15 is fixedly connected to the side of the box body 1 away from the box body 1 .

[0024] Furthermore, box 1 is an integrated sewage treatment box, in which a grid pool, a grease trap, a regulating pool, an anaerobic pool, an anoxic pool, an aerobic pool, an MBR membrane pool and a disinfection pool are sequentially arranged. Wastewater first enters the grid well of box 1 through a pipe, and after removing floating objects and particulate debris, it enters the grease trap for oil-water separation: solid-liquid separation and oil-water separation are completed by a fully automatic oil-water separator. Oily sewage first enters the solid-liquid separation cabin from the water inlet, and the solid residue is filtered out by a fine grid, and is sent out for collection by a spiral conveyor trough. The wastewater continues to flow into the oil-water separation cabin Through the mechanical demulsification of the fixed plate, the electric heating device can ensure that the grease is in a continuous liquid state in the upper layer and collected in the oil tank. The static sewage in the lower layer enters the regulating tank through the siphon device for step-by-step sedimentation, and the large particles of sewage are settled and the sewage is homogenized and equalized. Then, the liquid level controller transmits the signal, and the sewage is lifted by the lifting pump into the anaerobic biological pool, and the dissolved oxygen brought from the mixed liquid of the MBR membrane pool effluent and the biological filter sludge is fully utilized to ensure the normal denitrification of the anaerobic filter bed, and further nitrification reaction is carried out while removing oxygen;At the same time, the returned sludge is digested to provide a carbon source for denitrification and denitrification, and partial denitrification is carried out. The upper space of the anoxic tank is used to precipitate the suspended solids in the influent, and the mixed liquid is contacted with the aerobic tank. The polyphosphate bacteria in the sludge under anaerobic conditions release phosphorus so that phosphorus can be better adsorbed in the aerobic reaction. At the same time, the sludge adsorbs the organic matter in the sewage. Then, denitrification is carried out under anoxic conditions using the organic matter in the sewage as a carbon source to remove nitrate nitrogen and reduce the concentration of organic matter. Then, it flows into the aerobic biological contact oxidation tank for aerobic biochemical reactions, where most of the organic pollutants are assimilated and synthesized by microorganisms. The decomposition is carried out to form highly phosphorus-rich sludge, achieving a certain phosphorus removal effect. In the anoxic tank, the microorganisms are in an anoxic state. At this time, the microorganisms are facultative microorganisms. They convert and decompose the organic nitrogen in the sewage into ammonia nitrogen. At the same time, they use the organic carbon in the sewage as an electron donor to convert NO2-N and NO3-N in the sewage into N2, and also use part of the organic carbon source and NH4-N to synthesize new cell substances. Therefore, the anoxic tank not only has a certain organic matter removal function, reducing the organic load of the subsequent aerobic tank and MBR membrane tank to facilitate nitrification, but also relies on the organic carbon in the sewage to remove the organic matter. The higher concentration of organic matter in the aerobic biological pool completes denitrification and ultimately eliminates nitrogen eutrophication pollution. In the aerobic biological pool, since the concentration of organic matter has been greatly reduced, there is still a certain amount of organic matter and higher ammonia nitrogen. In order to further oxidize and decompose the organic matter, and at the same time, the nitrification can proceed smoothly when the carbonization is completed, an aerobic biochemical system with a low organic load is set up in the aerobic biological pool. The pool mainly contains aerobic microorganisms and autotrophic bacteria nitrifying bacteria. Among them, aerobic microorganisms decompose organic matter into CO2 and H2O, and autotrophic bacteria nitrifying bacteria use the Inorganic carbon or CO2 in the air is used as a nutrient source to convert NH4-N in the sewage into NO2-N and NO3-N. The effluent from the aerobic biological pool flows back to the anoxic pool to provide it with electron acceptors, and ultimately eliminates nitrogen pollution through denitrification, thereby achieving the ultimate goal of removing pollutants such as BOD, COD, ammonia nitrogen, total nitrogen, and total phosphorus in the sewage. Most organic pollutants are degraded through assimilation and dissimilation of microorganisms. The effluent flows by gravity to the MBR membrane pool for solid-liquid separation. The supernatant of the MBR membrane pool flows into the disinfection pool through the triangular cofferdam and is directly discharged after disinfection and deodorization.The driving device 16 is composed of a motor and a driving screw that can rotate forward and reverse. The output end of the motor is fixedly connected to the driving screw through a coupling. The driving device 16 is electrically connected to an external control power supply. The outer wall of the top of the driving screw is fixedly sleeved with a rotating bearing. The top of the rotating bearing is welded with a mounting plate. The side of the mounting plate close to the box body 1 is welded to the side of the box body 1 away from the box body 1. Two linkage plates 15 are provided, which are respectively welded to the top and bottom ends of the side of the movable clamp 5 close to the box body 1. A threaded groove is provided in the middle of the top of the linkage plate 15. The threaded groove is connected to the thread of the driving screw. Two limiting grooves 17 are provided, which are symmetrically arranged on both sides of the driving device 16. A T-slot is provided on the side of the limiting groove 17 away from the box body 1.

[0026] Furthermore, the inner wall of the first circular through groove is provided with an internal thread that meshes with the outer wall thread of the movable screw 6. By rotating the movable screw 6, the movable clamp 4 is moved towards or away from the movable clamp 5. The movable clamp 4 and the movable clamp 5 are provided with a groove on the opposite side for placing items taken out from the inside of the box 1. The distance between the movable clamp 5 and the movable clamp 4 can be adjusted by rotating, so that items of different sizes can be placed. The guide rod 7 can provide a guiding effect for the movable clamp 4 and can also prevent the movable clamp 4 from rotating. The size of the rectangular through groove corresponds to the size of the opening and closing door 8, and the opening and closing door 8 is aligned with the movable The clamp 4 is connected by a hinge, so that the opening and closing door 8 can be rotated, and the opening and closing door 8 is rotated away from the movable clamp 5. The bottom end of the inner wall of the rectangular through groove is flush with the bottom end of the inner wall of the groove of the movable clamp 4. Therefore, when transporting objects, it is only necessary to rotate and open the opening and closing door 8 to pull the object without lifting the object. When it is necessary to place the object, the opening and closing door 8 is rotated and the opening and closing door 8 and the movable clamp 4 are locked by the locking assembly. When the movable clamp 4 and the movable clamp 5 are moved to the top of one side of the box body 1 by the driving device 16, the object can be placed directly between the movable clamp 4 and the movable clamp 5.

[0028] Furthermore, two groups of locking components are provided, which are symmetrically arranged on both sides of the top of the opening and closing door 8. The bottom end of the locking block 11 is welded to the top of the movable clamp 4, and the bottom end of the fixed block 10 is welded to the top of the opening and closing door 8. The insertion hole is the same size as the locking hole, and the size of the baffle 13 is 1.1 times the size of the insertion hole. The baffle 13 and the pushing spring 14 are both in the cavity, and the pushing spring 14 is always in a compressed state in the cavity. The card block 12 is a right-angled triangular prism, and the inclined surface of the card block 12 faces the side close to the movable clamp 5. By moving closer to the fixed The fixed block 10 presses the card block 12 in the direction of the locking block 12 to disengage the locking hole, thereby releasing the lock of the opening and closing door 8, thereby rotating the opening and closing door 8 and transporting the items. When the opening and closing door 8 is locked, by rotating the opening and closing door 8 into the rectangular through groove, the card block 12 is squeezed by the outer wall of the locking block 11, and the opening and closing door 8 continues to be rotated. When the card block 12 moves to the locking hole position, under the action of the restoring force of the pushing spring 14, the baffle 13 is pushed to drive the card block 12 to be inserted into the locking hole, thereby locking the opening and closing door 8.
