Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to an underground integrated domestic sewage treatment equipment. Background Technology

[0002] Traditional domestic wastewater treatment equipment is mostly designed as a separate unit, requiring the construction of separate sedimentation tanks, aeration tanks, etc., which occupies a large area and is complex to install, making it particularly unsuitable for spaces such as residential communities and villages with limited space. Furthermore, the filter components of traditional equipment are inconvenient to disassemble and assemble, easily clogged by debris, affecting treatment efficiency, and the disinfection process often relies on chemical agents, posing a risk of secondary pollution and increasing the cost of chemical consumption. Therefore, there is an urgent need for an integrated, easy-to-maintain, pollution-free, and highly efficient domestic wastewater treatment system to meet practical application needs.

[0003] Existing technology authorization announcement number CN215712329U discloses a buried integrated domestic sewage treatment equipment, including an equipment shell and a sludge bottom frame fixed to the bottom of the equipment shell. The inner cavity of the equipment shell has a sedimentation tank in the middle, separated by an annular partition, and a filter tank and a purification tank on both sides. An inlet connecting to the filter tank is installed on one side of the top surface of the equipment shell. A dosing tank and a first motor are centrally installed on the top surface of the equipment shell. A feeding and stirring mechanism is installed on the top of the sedimentation tank, and this mechanism is connected to the first motor via a meshing component. An opening connecting to the filter tank is opened on the top side of the sedimentation tank, and a lift pump for connecting to the purification tank is provided on the outside of the sedimentation tank. This buried integrated domestic sewage treatment equipment allows for more uniform mixing of the sedimentation agent in the dosing tank with the sewage, improving the sedimentation efficiency of the sewage in the sedimentation tank and increasing the overall working efficiency.

[0004] Existing technologies improve the mixing effect of chemicals and sewage by installing a feeding and stirring mechanism at the top of the sedimentation tank, thereby increasing sewage sedimentation efficiency. However, in actual use, this sewage treatment equipment, relying solely on sedimentation, is insufficient to remove silt, floating matter, microorganisms, harmful bacteria, and other substances from the sewage, easily leading to secondary pollution of the environment after sewage discharge. Therefore, we propose a buried integrated domestic sewage treatment equipment, which solves the problems of limited functionality and poor sewage treatment effect of existing sewage treatment equipment, improves its treatment efficiency, and ultimately ensures environmental safety.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an underground integrated domestic sewage treatment equipment, including a treatment tank 1. The treatment tank 1 is equipped with a sedimentation and filtration tank 3, an aeration treatment tank 4 and a disinfection tank 5 through a partition plate 2. A rectangular groove 6 is opened at the upper end of the partition plate 2 between the sedimentation and filtration tank 3 and the aeration treatment tank 4. A slot 7 is opened inside the rectangular groove 6. A filter screen plate 8 is inserted inside the slot 7. The depth of the sedimentation and filtration tank 3 is two-fifths of the depth of the aeration treatment tank 4. A sewage inlet 10 is opened on the upper side wall of the sedimentation and filtration tank 3, and a sediment discharge outlet 11 is opened on its bottom side. A handle 12 is fixedly installed on the top of the filter screen plate 8.

[0019] In operation, domestic sewage enters the sedimentation and filtration tank 3 through the sewage inlet 10. Suspended impurities settle due to gravity, and the sediment is periodically discharged from the sediment outlet 11. After preliminary sedimentation, the sewage flows into the aeration treatment tank 4 through the rectangular trough 6 at the upper end of the partition plate 2. As it flows, it is further filtered by the filter screen 8 within the slot 7, removing smaller impurities. The filter screen 8 can be easily and quickly removed using the handle 12. After completing the biochemical reaction in the aeration treatment tank 4, the sewage enters the disinfection tank 5 for deep disinfection, ultimately meeting discharge standards. Each tank is independently separated by the partition plate 2. The sedimentation and filtration tank 3 is two-fifths the depth of the aeration treatment tank 4, facilitating the cleaning of sludge at the bottom of the sedimentation and filtration tank 3 by staff.

[0020] Three sets of ultraviolet disinfection lamps 9 are staggered at equal intervals on the inner wall of the disinfection tank 5. An aeration pipe 13 is fixedly installed on the bottom surface of the aeration treatment tank 4. Aeration heads 14 are evenly distributed at the top of the aeration pipe 13. A water pump 15 is detachably and fixedly installed at the bottom of the aeration pipe 13. A water supply pipe 16 is fixedly connected to the output end of the water pump 15. The top of the water supply pipe 16 extends into the interior of the disinfection tank 5. A sewage outlet 17 is opened on the bottom side of the aeration treatment tank 4. A sludge outlet 18 is opened on the bottom side of the disinfection tank 5. A drain outlet 19 is opened on the other side of the disinfection tank 5. The horizontal height of the drain outlet 19 is at least 20 centimeters greater than that of the sludge outlet 18.

[0021] During operation, the aeration treatment tank 4 is equipped with aeration pipes 13 at the bottom, and aeration heads 14 evenly distributed at the top release air bubbles, providing sufficient oxygen for the microorganisms in the tank and promoting biochemical reactions. After aeration treatment, the wastewater is transported to the disinfection tank 5 via a bottom pump 15 and a water supply pipe 16. Three ultraviolet disinfection lamps 9 are horizontally installed at equal intervals on the inner wall of the disinfection tank 5, which can perform three-dimensional deep sterilization of the wastewater. A sludge discharge port 18 is provided on the bottom side of the disinfection tank 5 to discharge the sediment generated during the disinfection process; a drain outlet 19 is provided on the other side, which is at least 20 cm higher than the sludge discharge port 18 to ensure that clean water is discharged first. A sewage discharge port 17 is also provided on the bottom side of the aeration treatment tank 4 to periodically discharge sludge and impurities in the tank, ensuring the efficient operation of the aeration system.

[0022] The top of the treatment tank 1 is hinged with a tank cover 20. Two lifting rings 21 are symmetrically welded to the top of the tank cover 20. A pre-reserved wiring hole 22 is provided in the middle of the tank cover 20. A switch control box 23 is fixedly installed on the top surface of the tank cover 20. The switch control box 23 is electrically connected to the ultraviolet disinfection lamp 9 and the water pump 15. On-off valves are installed on the outside of the sewage inlet 10, sediment outlet 11, sewage outlet 17, sludge outlet 18 and drain outlet 19.

[0023] In use, the top of the treatment tank 1 is hinged to a cover 20, which can be easily opened for maintenance of internal components. Two lifting rings 21 are symmetrically welded to the top of the cover 20 for easy hoisting and relocation of the entire equipment. A pre-drilled wiring hole 22 is provided in the middle of the cover 20 for cables of internal electrical components to pass through. The switch control box 23 fixed on the top surface is connected to the ultraviolet disinfection lamp 9 and the water pump 15 via circuitry to control the various devices inside the treatment tank 1. On / off valves are installed on the outside of the sewage inlet 10, sediment outlet 11, sludge outlet 17, sludge outlet 18, and drain outlet 19, which can flexibly control the opening and closing of each channel, facilitating equipment inspection and maintenance.

[0024] Working Principle: First, domestic sewage is discharged into the sedimentation and filtration tank 3 through sewage inlet 10. The silt and sand in the sewage undergo preliminary sedimentation inside the sedimentation and filtration tank 3. When the liquid level exceeds the rectangular trough 6, the sewage automatically overflows into the aeration treatment tank 4. During the overflow process, suspended paper pieces or flocculent matter in the water are separated and filtered by the filter screen 8 and retained inside the sedimentation and filtration tank 3. The sedimentation and filtration tank 3 is relatively shallow, and the filter screen 8 is installed on the upper end of the partition plate 2 using a top-to-bottom sliding insertion method, making it convenient for users to clean the sedimentation and filtration tank 3 and the filter screen 8, improving ease of use. After the sewage enters the aeration treatment tank 4, oxygen is supplied to the tank through an aeration device installed at the bottom of the aeration treatment tank 4, meeting the oxygen requirements of aerobic microorganisms for degrading organic matter. Simultaneously, airflow disturbance ensures thorough mixing of sewage, activated sludge, and oxygen, achieving the biological treatment effect in the sewage. Afterwards, the aerated wastewater is pumped into the disinfection tank 5 by water pump 15. Ultraviolet light is used to destroy the structure of pathogenic microorganisms in the wastewater, thereby achieving the harmless treatment of the wastewater. The disinfected wastewater is finally discharged through the drain outlet 19.
