[0028] An electric control box is also provided in the equipment room 2, which realizes the control of the circuit of the entire equipment and is integrated and uniformly managed;

[0029] On the other side inside the equipment body 1, a plurality of treatment tanks are provided. The treatment tanks include an anoxic tank 3, an aerobic tank 4, a clear water tank 5, a reaction tank 6 and a sedimentation tank 7. The sewage to be treated and purified externally passes through the reaction tank 6, sedimentation tank 7, anoxic tank 3, and aerobic tank 4 in sequence for treatment and purification, and then enters the clear water tank 5 for storage, and then the purified water is discharged, realizing the entire process of sewage treatment;

[0030] Specifically, a water inlet pipe 28 is installed on the reaction tank 6. The sewage from the outside is lifted into the reaction tank 6 through the water inlet pipe 28 by a submersible sewage pump or a centrifugal pump. The reaction tank 6 is connected to a chemical dosing pipe 10, and the other end of the chemical dosing pipe 10 is connected to a chemical dosing pump 24. After the chemical agent is added to the mixer 25, it is transported into the reaction tank 6 through the chemical dosing pump 24 and the chemical dosing pipe 10 to achieve sewage treatment;

[0031] The treated water in the reaction tank 6 enters the sedimentation tank 7. After sedimentation, the mud and water are separated. Larger particles and insoluble organic matters are adsorbed by the surplus activated sludge and then flocculated and precipitated. They are refluxed into the reaction tank 6 through the sludge pump 27. Then, the surplus sludge in the reaction tank 6 is regularly discharged, and the supernatant flows into the anoxic tank 3 through the overflow weir 16;

[0032] An air diffuser pipe 8 is also provided in the reaction tank 6. The air inlet end of the air diffuser pipe 8 is connected to a blower 22 installed in the equipment room 2. After the blower 22 is started, it transports the gas into the reaction tank 6 through the air diffuser pipe 8 to achieve aeration and mixing;

[0033] A sludge discharge pipe 14 is provided at the bottom of the sedimentation tank 7. Sludge pumps 27 are installed and connected to both the sedimentation tank 7 and the reaction tank 6. The sludge pumps 27 can clean the surplus sludge in the reaction tank 6 and the sludge in the sedimentation tank 7.

Moreover, a baffle 15 is provided in the sedimentation tank 7. An overflow weir 16 is provided on one side of the baffle 15. An overflow trough 17 is formed between the overflow weir 16 and the sedimentation tank 7. The water passing hole 12 is communicated with the overflow trough 17. Thus, the supernatant in the sedimentation tank 7 enters the overflow trough 17 and then is discharged into the anoxic tank 3 through the water passing hole 12. The anoxic tank 3 combines the two biological reaction processes of denitrification and organic matter degradation, and provides different reaction conditions for organic matter degradation and denitrification in the anoxic and aerobic sections, achieving the purpose of removing both organic matter and nitrogen;

[0034] The anoxic tank 3 is communicated with the aerobic tank 4 through a water passing hole 13. The sewage after reaction in the anoxic tank 3 enters the aerobic tank 4. A reflux pump 18 is installed in the aerobic tank 4. The outlet of the reflux pump 18 is connected to a reflux pipe 19. The outlet of the reflux pipe 19 is communicated with the anoxic tank 3. The nitrified liquid in the aerobic tank 4 flows back into the anoxic tank 3 through the reflux pipe 19;

[0035] In the aerobic tank 4, a microporous aeration device 26 and an MBR membrane mechanism 29 are also installed. The microporous aeration device 26 is connected to the blower 22 through an aeration pipe 8.

The connection between the water production suction pipe 11 and the water production pump 20 can directly discharge the purified clear water from the MBR membrane mechanism 29. The MBR membrane mechanism 29 uses aerobic microorganisms in the reactor to degrade organic pollutants in the sewage. At the same time, nitrifying bacteria in the reactor are used to convert ammonia nitrogen in the sewage, and then solid-liquid separation and water discharge are carried out through a hollow fiber membrane.

[0036] The purified water in the aerobic tank 4 is pumped into the water production pipe 9 through the water production pump 20 installed in the equipment room 2. The water production pipe 9 is connected to the clear water tank 5, and thus the clear water obtained from the aerobic tank 4 is transported to the clear water tank 5 for storage.

[0037] The treatment of rural domestic sewage is an important part of the improvement of rural human settlements environment. The development of integrated rural domestic sewage and sludge treatment equipment is necessary for rural sewage and small town sewage treatment. The integrated equipment of the present utility model has the following advantages:

[0038] Water resource conservation: After the treatment of sewage in rural areas, the treated water resources can be used for domestic, agricultural or industrial water, realizing the recycling of water resources, thus saving the cost of water resource development.

[0039] Reduction of environmental pollution: In the process of rural urbanization, a large amount of sewage is directly discharged into rivers and lakes, seriously affecting the water environment quality. Through sewage treatment, the degree of environmental pollution can be effectively reduced and the water quality can be improved.
