Description

Technical Field

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

A sediment rising component for rising sediment at the bottom of the upper tank body 101 is arranged 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 arranged on the sediment rising component.

[0037] Specifically, after the sewage is discharged into the grid filter tank, it is subjected to step-by-step reaction treatment. The sewage in the upper reaction tank is discharged to the next 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 work, and the aeration component inputs oxygen into the sewage in the upper tank body 101, and the organic matter in the sewage is contacted and decomposed by microorganisms, wherein a part of the organic matter with large particles gradually sinks to the bottom of the upper tank body 101. By setting a sediment rising component, the organic matter precipitate 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 setting a crushing component, after the large organic matter falls to the bottom of the upper tank body 101, the large organic matter can be crushed, so that the small organic matter can fully contact and react with the microorganisms, thereby effectively improving the decomposition efficiency of solid organic matter.

By controlling the operation of the driving motor 401, the output shaft of the driving 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 up through the first elastic telescopic rod 602, so that the lifting seat 5 fits the bottom wall of the conveying pipe 3. As the first sleeve 601 continues to move up, 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 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 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-accept the large particles of organic matter that have fallen on the bottom of the upper pool body 101, thereby effectively improving the decomposition efficiency of solid organic matter.

An integrated sewage treatment method, which is carried out by applying the integrated sewage treatment system according to claim 9, characterized in that: The following steps are involved: S1: When the sewage enters the first aerobic tank or the second aerobic tank, the blower (9) is controlled to operate so that the blower (9) inputs oxygen into the sewage in the upper tank body (101) through the aeration plate (903), and 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) is in contact 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 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 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, and the first sleeve (601) automatically resets and moves downward after moving to the upper end of the first reciprocating screw (6), 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) meshes 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 up and down along the axis of the second reciprocating screw (801), so that the moving block (802) drives the crushing plate (804) to move 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), so that the aeration disk (903) on the ring body (9022) rotates in a circle. The bubbles discharged by the aeration disk (903) are evenly scattered in the sewage in the upper tank body (101), thereby accelerating the decomposition of solid organic matter in the sewage.
