Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to an integrated sewage treatment system and method. Background Art

[0002] The integrated sewage treatment system is a sewage treatment system that integrates the primary sedimentation tank, I and II stage contact oxidation tanks, secondary sedimentation tank, and sludge tank. Aeration is carried out in the I and II stage contact oxidation tanks to effectively combine the contact oxidation method and the activated sludge method, saving the tedious work of finding people to design sewage treatment processes and doing infrastructure construction.

[0003] By performing aeration in the contact oxidation tank, the oxygen content in the sewage can be increased to promote the growth of microorganisms to decompose the organic matter in the sewage. Some of the organic matter in the sewage has large particles. As the contact oxidation proceeds, some of the large organic matter particles sink to the bottom of the contact oxidation tank, reducing the probability of organic matter particles contacting microorganisms and reducing the decomposition efficiency of the organic matter.

[0015] The present invention also discloses an integrated sewage treatment method, which is carried out by applying an integrated sewage treatment system, comprising the following steps:

[0016] S1: When the sewage enters the first aerobic tank or the second aerobic tank, the blower is controlled to input oxygen into the sewage in the upper tank through the aeration plate. The organic matter in the sewage is decomposed by contact with microorganisms, and some of the large organic matter particles gradually sink to the lifting seat at the bottom of the upper tank;

[0017] S2: Control the operation of the driving motor, the output shaft of the driving motor drives the rotating shaft to rotate, and the rotating shaft drives the first reciprocating screw at the bottom to rotate. When the first reciprocating screw rotates, the first sleeve moves axially along the first reciprocating screw, and the first sleeve drives the lifting seat to move upward through the first elastic telescopic rod, so that the lifting seat fits the bottom wall of the conveying pipe. As the first sleeve continues to move upward, the first elastic telescopic rod is compressed, and the spiral conveying blades on the rotating shaft push the lifting seat to convey the organic matter in the conveying pipe upward, so that the large particles of organic matter that sink to the bottom of the upper pool body re-enter the top of the upper pool body from the discharge port, so that the organic matter is re-contacted with microorganisms and decomposed when falling. After moving to the upper end of the first reciprocating screw, the first sleeve automatically resets and moves downward, so that the lifting seat re-picks up the large particles of organic matter that have fallen on the bottom of the upper pool body;

[0018] S3: When the rotating shaft rotates, the rotating plate drives the rotating rod to move around the circumference of the conveying pipe. When the rotating rod moves, the driven gear engages with the fixed gear for transmission, so that the rotating rod can rotate during its revolution. The rotating rod drives the second reciprocating screw to rotate, and the moving block reciprocates up and down along the axis of the second reciprocating screw. The moving block drives the crushing plate to reciprocate up and down through the second elastic telescopic rod. The crushing plate cooperates with the bottom wall of the upper tank body to crush large particles of organic matter that fall to the bottom of the upper tank body, breaking the large particles of organic matter into small particles. The small particles of organic matter can fully come into contact with microorganisms and decompose;

[0019] S4: When the rotating rod rotates, the connecting plate drives the ring body to rotate relative to the bottom plate, causing the aeration disk on the ring body to rotate in a circle. The bubbles discharged by the aeration disk are evenly scattered in the sewage in the upper tank body, accelerating the decomposition of solid organic matter in the sewage.

[0020] Compared with the prior art, the present invention provides an integrated sewage treatment system and method, which has the following beneficial effects:

[0021] 1. This integrated sewage treatment system and method, by providing a sediment raising component, can transport the organic matter sediment that has sunk to the bottom of the upper tank body to the upper side of the upper tank body, so that the organic matter can come into contact with microorganisms again and react, thereby effectively improving the decomposition efficiency of solid organic matter.

[0022] 2. This integrated sewage treatment system and method is equipped with a crushing component. After large particles of organic matter fall to the bottom of the upper tank, the crushing plate can crush the large particles of organic matter, allowing small particles of organic matter to fully contact and react with microorganisms, effectively improving the decomposition efficiency of solid organic matter.

[0023] 3. The integrated sewage treatment system and method provides a protective tube on the outside of the second sleeve to protect the second reciprocating screw rod, thereby preventing debris in the sewage from entering the track groove of the reciprocating screw rod and affecting the normal up and down reciprocating movement of the second sleeve, thereby ensuring the smooth crushing work of the crushing assembly.

[0024] 4. This integrated sewage treatment system and method uses a connecting plate to drive the ring body to rotate relative to the bottom plate when the rotating rod rotates, so that the aeration disk on the ring body rotates in a circular motion. The bubbles discharged by the aeration disk are evenly scattered in the sewage in the upper tank body, accelerating the decomposition of solid organic matter in the sewage.

The first aerobic tank and the second aerobic tank have the same structure and both include a working tank 1. The working tank 1 includes an upper tank body 101 and a lower seat body 102 arranged at the lower side of the upper tank body 101. An aeration component is provided at the upper tank body 101. A sediment rising component for rising sediment at the bottom of the upper tank body 101 is provided in the upper tank body 101. The sediment rising component is placed in the middle of the upper tank body 101. A crushing component for crushing large particles of organic matter is provided on the sediment rising component.

[0037] Specifically, after the sewage enters the grid filter tank, it undergoes a step-by-step reaction treatment. The sewage in the upper reaction tank is discharged to the lower reaction tank through a water pump, and finally the clear liquid enters the clear liquid storage tank and is discharged by a water pump. It should be noted that the grid filter tank, the first anaerobic tank, the second anaerobic tank and the clear liquid storage tank are all existing technologies and will not be described in detail here. When the sewage enters the first aerobic tank or the second aerobic tank, the aeration component is controlled to operate, and the aeration component inputs oxygen into the sewage in the upper tank body 101. Organic matter in the sewage is contacted with microorganisms for decomposition, and some large organic matter particles gradually sink to the bottom of the upper tank body 101. By providing a sediment raising component, the organic matter sediment that sinks to the bottom of the upper tank body 101 can be transported to the upper side of the upper tank body 101, so that the organic matter can contact and react with the microorganisms again, thereby effectively improving the decomposition efficiency of solid organic matter. By providing a crushing component, the large organic matter particles can be crushed after falling to the bottom of the upper tank body 101, so that the small organic matter particles can fully contact and react with the microorganisms, thereby effectively improving the decomposition efficiency of solid organic matter.

[0038] Reference Figure 1 、 Figure 2 、 Figure 5 and Figure 6 As a preferred technical solution of the present invention, the sediment rising component includes a conveying pipe 3 fixed in the upper pool body 101 through a support rod 2, the bottom of the conveying pipe 3 is provided with an opening and the upper part is provided with a discharge port 301, the top of the upper pool body 101 is fixed with a mounting plate 4, and a driving motor 401 is fixed on the mounting plate 4. The output shaft of the driving motor 401 is connected to a rotating shaft 402 rotating in the conveying pipe 3, and a spiral conveying blade 403 is provided on the rotating shaft 402.

[0039] Furthermore, the sediment rising assembly also includes a lifting seat 5 slidably connected to the bottom of the upper pool body 101, and a first reciprocating screw 6 connected to the rotating shaft 402 is rotatably connected in the lower seat body 102. The outer side of the first reciprocating screw 6 is threadedly connected to the first sleeve 601, and the first sleeve 601 is fixed with a first elastic telescopic rod 602 connected to the lifting seat 5.

[0040] Specifically, the organic matter in the sewage comes into contact with the microorganisms and decomposes, and some of the organic matter with large particles gradually sinks to the lifting seat 5 at the bottom of the upper pool body 101. By controlling the operation of the drive motor 401, the output shaft of the drive motor 401 drives the rotating shaft 402 to rotate, and the rotating shaft 402 drives the first reciprocating screw rod 6 at the bottom to rotate. When the first reciprocating screw rod 6 rotates, the first sleeve 601 moves axially along the first reciprocating screw rod 6, and the first sleeve 601 drives the lifting seat 5 to move upward through the first elastic telescopic rod 602, so that the lifting seat 5 fits with the bottom wall of the conveying pipe 3. As the first sleeve 601 continues to move upward, the first elastic telescopic rod 602 is compressed, and the rotating shaft 4 The spiral conveying blades 403 on 02 push the lifting seat 5 to transport the organic matter in the conveying pipe 3 upward, so that the large particles of organic matter that sink to the bottom of the upper pool body 101 re-enter the top of the upper pool body 101 from the discharge port 301, so that the organic matter can re-contact with the microorganisms for decomposition when falling. After moving to the upper end of the first reciprocating screw 6, the first sleeve 601 automatically resets and moves downward, so that the lifting seat 5 can re-pick up the large particles of organic matter that have fallen at the bottom of the upper pool body 101, thereby effectively improving the decomposition efficiency of solid organic matter. It should be noted that the top of the lifting seat 5 should be set to an arc with a concave middle to avoid most of the large particles of organic matter from being scattered during the upward movement of the lifting seat 5.

[0044] Specifically, when the rotating shaft 402 rotates, the rotating rod 8 is driven to move around the circumference of the conveying pipe 3 through the rotating plate 4021. When the rotating rod 8 moves, the driven gear 805 is meshed with the fixed gear 302 for transmission, so that the rotating rod 8 can rotate during the revolution. The rotating rod 8 drives the second reciprocating screw rod 801 to rotate, and the moving block 802 moves back and forth along the axis of the second reciprocating screw rod 801. The guide rod 701 limits the moving direction of the moving block 802, so that the moving block 802 drives the crushing plate 804 to move back and forth up and down through the second elastic telescopic rod 803. The crushing plate 804 cooperates with the upper The bottom wall of the pool body 101 crushes the large particles of organic matter that fall to the bottom of the upper pool body 101, so that the large particles of organic matter are broken into small particles of organic matter. The small particles of organic matter can fully contact and decompose with microorganisms, effectively improving the decomposition efficiency of solid organic matter; by arranging a protective tube 8022 on the outside of the second sleeve 8021, the protective tube 8022 protects the second reciprocating screw 801, preventing debris in the sewage from entering the track groove of the reciprocating screw and affecting the normal up and down reciprocating movement of the second sleeve 8021, thereby ensuring the smooth progress of the crushing work of the crushing assembly.

A plurality of aeration disks 903 are evenly arranged on the aeration ring 902 in a circumferential pattern. Specifically, when the sewage enters the first aerobic tank or the second aerobic tank, the blower 9 is controlled to operate so that the gas discharged from the blower 9 passes through the air duct 901, the aeration ring 902, and finally through the aeration disks 903 to input oxygen into the sewage in the upper tank body 101, so that organic matter in the sewage is decomposed by contact with microorganisms.

One end of the air guide tube 901 passes through the base plate 9021 and is connected to the aeration plate 903 through the internal cavity of the ring body 9022.

[0047] Furthermore, a connecting plate 10 is fixedly provided on the ring body 9022 , and one end of the connecting plate 10 away from the ring body 9022 is connected to the rotating rod 8 .

[0048] Specifically, when the rotating rod 8 rotates, the connecting plate 10 drives the ring body 9022 to rotate relative to the bottom plate 9021, causing the aeration plate 903 on the ring body 9022 to rotate in a circle. The bubbles discharged by the aeration plate 903 are evenly scattered in the sewage in the upper tank body 101, thereby accelerating the decomposition of solid organic matter in the sewage and improving the decomposition efficiency of organic matter.

As the first sleeve 601 continues to move upward, the first elastic telescopic rod 602 is compressed, and the spiral conveying blades 403 on the rotating shaft 402 push the lifting seat 5 to convey the organic matter in the conveying pipe 3 upward, so that the large particles of organic matter that sink to the bottom of the upper pool body 101 re-enter the top of the upper pool body 101 through the discharge port 301, so that the organic matter is re-contacted with microorganisms and decomposed when falling.

Organic matter in the sewage is decomposed by contact with microorganisms, and a portion of the organic matter with large particles gradually sinks to the lifting seat (5) at the bottom of the upper tank body (101); S2: Control the driving motor (401) to operate, the output shaft of the driving motor (401) drives the rotating shaft (402) to rotate, the rotating shaft (402) drives the first reciprocating screw (6) at the bottom to rotate, when the first reciprocating screw (6) rotates, the first sleeve (601) moves along the axial direction of the first reciprocating screw (6), the first sleeve (601) drives the lifting seat (5) to move upward through the first elastic telescopic rod (602), so that the lifting seat (5) fits with the bottom wall of the conveying pipe (3), and as the first sleeve (601) continues to move upward, the first elastic telescopic rod (602) 02) is compressed, and the spiral conveying blades (403) on the rotating shaft (402) push the lifting seat (5) to transport the organic matter in the conveying pipe (3) upward, so that the large particles of organic matter that sink to the bottom of the upper tank body (101) re-enter the top of the upper tank body (101) through the discharge port (301), so that the organic matter is re-contacted with microorganisms for decomposition when falling. After moving to the upper end of the first reciprocating screw (6), the first sleeve (601) automatically resets and moves downward, so that the lifting seat (5) re-receives the large particles of organic matter that fall to the bottom of the upper tank body (101); S3: When the rotating shaft (402) rotates, the rotating rod (8) is driven to move around the circumference of the conveying pipe (3) through the rotating plate (4021). When the rotating rod (8) moves, the driven gear (805) is meshed with the fixed gear (302) for transmission, so that the rotating rod (8) can rotate during the revolution. The rotating rod (8) drives the second reciprocating screw (801) to rotate, and the moving block (802) moves back and forth along the axis of the second reciprocating screw (801), so that the moving block (802) drives the crushing plate (804) to move back and forth up and down through the second elastic telescopic rod (803). The crushing plate (804) cooperates with the bottom wall of the upper pool body (101) to crush the large particles of organic matter that fall to the bottom of the upper pool body (101), so that the large particles of organic matter are broken into small particles of organic matter, and the small particles of organic matter can fully contact with microorganisms for decomposition; S4: When the rotating rod (8) rotates, the connecting plate (10) drives the ring body (9022) to rotate relative to the bottom plate (9021), causing the aeration disk (903) on the ring body (9022) to rotate in a circular motion. The bubbles discharged from the aeration disk (903) are evenly dispersed in the sewage in the upper tank body (101), thereby accelerating the decomposition of solid organic matter in the sewage.
