[0002] With the advancement of sewage treatment technology and the improvement of treatment requirements, the difficulty of operation and management of sewage treatment equipment and the energy consumption of operation have also increased. Point source sewage has the characteristics of small water volume, unstable water quality and quantity, scattered treatment points, and difficult operation and maintenance management.

[0003] In the current traditional sewage treatment process, there are a lot of energy consumption problems in sewage lifting and sludge transportation, biological treatment oxygen supply and sludge treatment. In particular, the proportion of aeration energy consumption, sludge return and sewage lifting energy consumption in biological treatment is relatively large. In addition, traditional sewage treatment equipment uses more mechanical equipment, and the functional division of the pool is complex, resulting in more control factors, more complex equipment linkage logic, and higher requirements for operation and management personnel and equipment. This results in increased energy consumption and increased operation and maintenance management costs.

At the same time, we rationally optimize the equipment structure, rely on efficient treatment technology, formulate scientific energy-saving and emission reduction measures, improve equipment processing efficiency, reduce equipment operating energy consumption, simplify equipment operation and maintenance management, and effectively solve the problem of energy waste.

[0046] The working principle of this micro-power integrated sewage treatment equipment:

[0047] 1. Pre-hypoxia zone 1

[0048] The sewage enters the pre-anoxic zone 1 through the water inlet pipe, and the sludge is returned to the pre-anoxic zone 1 to remove the nitrate nitrogen in the returned sludge, which also plays a role in supplementing the activated sludge, creating better anaerobic conditions for the anaerobic tank, which is conducive to the anaerobic phosphorus release of polyphosphate bacteria, strengthening the phosphorus absorption effect of the aerobic tank, and strengthening the nitrogen and phosphorus removal effect of the system. An air stirring device 11 is installed at the bottom of the pre-anoxic zone 1 to provide mixing and stirring power for the sewage and returned sludge in the pre-anoxic zone 1;

[0049] 2. Anaerobic Zone 2

[0050] The soluble and easily degradable organic matter in the sewage is combined with the polyphosphate bacteria to absorb the organic matter and release P at the same time, so as to prepare for the subsequent aerobic stage to fully absorb the total phosphorus, and ensure a high total phosphorus removal effect in the biochemical stage. An air stirring device 11 is installed at the bottom of the anaerobic zone 2 to prevent the mixed liquid from sludge in the anaerobic zone 2 and ensure the complete mixing state of the mixed liquid in the area. An air stirring device 11 is installed at the bottom of the anaerobic zone 2 to provide mixing and stirring power for the sewage and the mixed liquid in the anaerobic zone 2;

[0051] 3. Hypoxic Zone 3

[0052] The nitrified liquid in the air stripping reflux zone 6 flows back to the anoxic zone 3, and the effluent from the anaerobic zone 2 enters the anoxic zone 3. An air stirring device 11 is installed at the bottom of the anoxic zone 3 to ensure that the sewage and the refluxed nitrified liquid are completely mixed in the anoxic zone 3, and the denitrification reaction is fully carried out, thereby realizing the removal of total nitrogen in the sewage. An air stirring device 11 is installed at the bottom of the anoxic zone 3 to provide mixing and stirring power for the sewage and the refluxed sludge in the anoxic zone 3;

[0053] 4. Aerobic Zone 4

[0054] The effluent from the end of the anoxic zone 3 enters the aerobic zone 4. An aeration device 41 is installed at the bottom of the aerobic zone 4 to provide oxygen and achieve sufficient stirring. Under an aerobic environment, aerobic microorganisms in the sewage inorganicize part of the organic matter in the sewage through oxidation, reduction, synthesis and other processes, and part of the organic matter is synthesized into cell substances of microbial aerobic bacteria. In order to avoid short-circuiting, the structure of the aerobic zone 4 is optimized into a corridor structure by setting partition walls in the aerobic zone 44, which prolongs the sewage retention time and forms a plug flow state in the aerobic zone 4. Through the reasonable design and control of the aeration system, better nitrogen and phosphorus removal effects can be achieved, which is helpful for oxygen transfer, liquid mixing and sludge flocculation;

[0055] V. Sedimentation and separation zone 5:

[0056] The aerobic zone 4 and the sedimentation separation zone 5 are connected through the baffle gaps. The aeration device 41 at the bottom of the aerobic zone 4 can not only supply oxygen but also lift the mixed liquid upward. Most of the bubbles burst in the upward process to provide oxygen to the mixed liquid. Part of the mixed liquid with bubbles goes down along the baffle gaps into the sedimentation separation zone 5. When the mixed liquid floats to a balance between gravity and buoyancy, a suspended sludge layer is formed, which can intercept the suspended substances in the subsequent mixed liquid. The mixed liquid continues to rise and passes through the inclined plate area. After the remaining suspended matter and sludge settle on the inclined plate, they fall to the bottom of the separation zone along the inclined plate. The sludge at the bottom of the sedimentation separation zone 5 reaches the air lift reflux zone 6 along the reflux seam, and finally the clarified effluent reaches the top of the separation zone and merges into the outlet channel 7.

[0057] Three-phase separation assembly: The three-phase separation structure is composed of a special structure at the bottom of the sedimentation separation zone 5, which takes into account the three functions of gas-liquid separation, solid-liquid separation and sludge return: there are three fluids rising and falling simultaneously in the sedimentation separation zone 5;

[0058] The three-phase separation structure is intended to form a channel through vertical partitions and inclined plates, conforming to the characteristics of the three fluids of solid, liquid and gas. The gap formed by the inner and outer vertical partitions on the right first guides the mixed liquid to flow downward, and the gas rises. The inner inclined plate can not only intercept the vertically rising bubbles, but also guide the sinking solids to flow to the opposite side. The mixed liquid enters the bottom of the sedimentation separation zone 5. The bottom of the separation zone is provided with a triangular flow stabilizer 52, which improves the uniformity and stability of the rising fluid, improves the solid sedimentation efficiency, and is conducive to the sedimentation and separation of fine flocs. In the process of the solid-liquid mixed fluid moving vertically upward, due to the density difference between the solid and the liquid, the solid sinks based on gravity and flows back to the bottom of the sedimentation separation zone 5 along the self-adaptive adjustable inclined plate 8 and the inclined edge of the triangular flow stabilizer 52, and is lifted to the reflux area by the left gas lift reflux device. Part of the sludge is deposited at the bottom of the self-adaptive adjustable inclined plate 8. When the sludge is deposited to a certain weight and exceeds the counterweight of the self-adaptive adjustable inclined plate 8, the metal plate 82 rotates around the rotating shaft 83 to make the deposited sludge slide down to the gas lift reflux zone 6.

[0059] The structure is designed based on the density, kinematic viscosity and other physical properties of the three-phase fluid, which can ensure that the residence time between the precipitation and separation zones 5 is sufficient, and the reflux gap can ensure that the speed of the fluid passing through is appropriate, so that the precipitated solids can quickly and smoothly return to the gas stripping reflux zone 6, and have a good solid-liquid separation effect;

[0060] 6. Gas Lifting Reflux Zone 6

[0061] The bottom of the air lift reflux zone 6 is connected to the reflux seam at the bottom of the sedimentation and separation zone 5. An aeration device 41 is installed at the bottom of the air lift reflux zone 6, which can not only realize the air stirring function to avoid the occurrence of sludge, but also form a density difference between the air lift reflux zone 6 and the sedimentation and separation zone 5, thereby providing power for the air lift reflux at the bottom of the sedimentation and separation zone 5, so that the mixed liquid after precipitation flows smoothly to the air lift reflux zone 6. The outlet of the air lift reflux zone 6 is connected to the pre-anoxic zone 1 and the anoxic zone 3, and the nitrate nitrogen in the reflux liquid is introduced into the anoxic environment. The denitrifying bacteria use the easily degradable organic matter for denitrification, thereby achieving the purpose of removing nitrate nitrogen, further improving the denitrification capacity of the integrated sewage treatment equipment. At the same time, a sludge discharge valve is provided at the bottom of the air lift reflux zone 6, and accurate static pressure sludge discharge can be achieved through the valve switch in conjunction with the sludge concentration monitoring instrument;

[0062] VII. Equipment Room 9

[0063] The equipment room 9 mainly contains: air supply fans, supporting equipment of the photovoltaic power supply system 10, control systems, power distribution cabinets, etc. The equipment room 9 can be coupled with the sewage treatment area to form an integral device, or it can be set up independently.

[0064] 8. Photovoltaic power supply system 10

[0065] The photovoltaic power supply system 10 is composed of a photovoltaic module, a controller 102, a battery 103 and an inverter 104. During the day, sunlight shines on the photovoltaic module, generating a DC voltage, converting light energy into electrical energy, which is then transmitted to the controller 102. After the overcharge protection of the controller 102, the electricity from the photovoltaic module is transmitted to the battery 103 for storage, and then the DC power is converted into AC power through the inverter 104 for use by electrical equipment. In the present invention, the photovoltaic power supply system 10 mainly supplies power to the fan, the control system 9 and the lighting facilities supporting the equipment;

[0066] 9. Control system

[0067] By utilizing the significant correlation between online monitoring data and the state of biological reactions, a program is designed in advance to change the operating conditions of the treatment process by adjusting the fan operating time, frequency conversion, valve start and stop, the inclination angle of the adaptive adjustable inclined plate 8, and the photovoltaic power supply system 10. This allows the equipment operating status to be flexibly adjusted according to actual conditions and environmental changes, thereby improving equipment processing efficiency, reducing equipment operating energy consumption, and simplifying operation and maintenance management.

[0068] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
