Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a skid-mounted sewage treatment device for ecological environment governance. Background Technique

[0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it, which is an important part of ecological environment governance. Sewage treatment devices are usually used in the sewage treatment process. The existing skid-mounted sewage treatment devices usually have an aeration tank and a sedimentation tank. Inevitably, there will be solid waste in the sewage. Therefore, a grille is set at the inlet of the aeration tank of the existing sewage treatment device to filter the solid waste in the sewage. However, too much garbage accumulation on the grille will affect the water flow, and some garbage can also be recycled. Therefore, it is necessary to regularly clean and recycle the garbage on the grille. At present, most of the garbage cleaning and recycling work is completed manually, which not only increases the workload of workers, but also has a low recycling efficiency.

[0003] Therefore, we design a skid-mounted sewage treatment device for ecological environment governance here. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 - 3, in this implementation: A skid-mounted sewage treatment device for ecological environment governance includes a water tank 1. Inside the water tank 1, there is an aeration tank 1-1 and a sedimentation tank 1-2. The aeration tank 1-1 is located behind the sedimentation tank 1-2. A pipe body 2 is installed between the left and right inner sidewalls of the aeration tank 1-1. The pipe body 2 is close to the top of the aeration tank 1-1. A number of evenly distributed filter holes are provided on the pipe wall of the pipe body 2. A screw conveyor 3 is rotatably installed between the centers of the circular inner walls at the left and right ends of the pipe body 2. An inlet 2-1 is provided at the right top of the pipe body 2, and a water inlet pipe 8 is installed on the inlet 2-1. A discharge port 2-2 is provided at the left bottom of the pipe body 2. When sewage enters the inside of the pipe body 2 through the water inlet pipe 8, the water will pass through the filter holes on the pipe wall of the pipe body 2 and fall into the aeration tank 1-1, and the solid waste in the sewage will remain in the pipe body 2. If the sewage discharge is large, the number of inlets 2-1 on the pipe body 2 can be appropriately increased according to actual needs. If the sewage discharge is small, the number of inlets 2-1 on the pipe body 2 can be appropriately reduced according to actual needs, but there must be at least one inlet 2-1.

[0019] A discharge port 1-4 is provided on the left side of the water tank 1. A guiding slope 6 is installed inside the discharge port 1-4. The guiding slope 6 is directly below the discharge port 2-2 of the pipe body 2. A downward-sloping discharge pipe 7 is installed outside the discharge port 1-4. A collection box 9 is placed on the left side of the water tank 1. The collection box 9 is directly below the outlet of the discharge pipe 7. A reduction gearbox 4 and a motor 5 are installed on the right side of the water tank 1. The input end of the reduction gearbox 4 is connected to the output shaft of the motor 5, and the output end of the reduction gearbox 4 is connected to the main shaft of the screw conveyor 3. Starting the motor 5 can drive the screw conveyor 3 to rotate. By rotating the screw conveyor 3, the solid waste in the pipe body 2 can be pushed towards the discharge port 2-2 of the pipe body 2, so that the waste is discharged from the discharge port 2-2. The waste discharged from the pipe body 2 will fall on the guiding slope 6, and then be discharged from the water tank 1 through the guiding slope 6 and the discharge pipe 7. All the waste will finally be centrally collected in the collection box 9. A baffle is provided on the side of the guiding slope 6 to prevent the waste on the slope from sliding into the aeration tank 1-1.

[0020] Please refer to Figure 3, an air diffuser pipe 10 is installed at the bottom of the aeration tank 1-1. The air inlet of the air diffuser pipe 10 is connected to a blower through a pipe. When the blower is started, the sewage in the aeration tank 1-1 can be aerated through the air diffuser pipe 10. During aeration, activated sludge should be added to the sewage in the aeration tank 1-1. Microorganisms in the activated sludge can convert organic substances in the sewage into harmless substances through biodegradation during the sewage treatment process. A water pump 12 is installed at the top of the water tank 1. Both the water inlet end and the water outlet end of the water pump 12 are connected to pipes. The pipe at the water inlet end leads to the bottom of the aeration tank 1-1, and the pipe at the water outlet end leads to the top of the sedimentation tank 1-2. When the water pump 12 is started, the sewage in the aeration tank 1-1 can be pumped into the sedimentation tank 1-2 for sedimentation. A drain port 1-3 is provided on the front side wall of the sedimentation tank 1-2, and the drain port 1-3 is close to the top of the sedimentation tank 1-2. After the treated sewage enters the sedimentation tank 1-2, the sludge will gradually settle to the bottom of the sedimentation tank 1-2. When the liquid level in the sedimentation tank 1-2 rises, the supernatant will be discharged from the drain port 1-3. A sludge pump 11 is installed at the bottom of the sedimentation tank 1-2. A sludge discharge pipe is connected to the sludge discharge port of the sludge pump 11. The function of the sludge pump 11 is to clean the sludge at the bottom of the sedimentation tank 1-2.

[0021] Working principle and usage process of the present utility model: When this skid-mounted sewage treatment device for ecological environment governance is in use, sewage is discharged into the pipe body 2 through the water inlet pipe 8. After the sewage enters the pipe body 2, the liquid passes through the filter holes on the pipe wall of the pipe body 2 and falls into the aeration tank 1-1, and the solid garbage in the water remains in the pipe body 2. Activated sludge is added to the sewage in the aeration tank 1-1, and the blower is started. The sewage is aerated through the air diffuser pipe 10 to accelerate the mixing of the sewage and the activated sludge. Microorganisms in the activated sludge convert organic substances in the sewage into harmless substances through biodegradation. After a period of time, the water pump 12 is started to pump the water in the aeration tank 1-1 into the sedimentation tank 1-2 for sedimentation. The water level in the sedimentation tank 1-2 gradually rises, and the supernatant is finally discharged from the drain port 1-3. After the sewage treatment is completed, the motor 5 is started, and the motor 5 drives the auger 3 to rotate. The garbage in the pipe body 2 is pushed towards the discharge port 2-2 through the auger 3, so that the garbage in the pipe body 2 is automatically discharged from the discharge pipe 7, and the garbage is finally centrally recovered in the collection frame 9.
