Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a sewage treatment device. Background Art

[0002] There are many methods for sewage treatment, among which aerobic treatment refers to the biochemical process of degrading organic matter and converting it into humus-like substances with the participation of microorganisms under suitable carbon-nitrogen ratio, water content and oxygen conditions. Aerobic treatment technology is considered to be an effective method for organic solid waste treatment because it can achieve the treatment goals of solid waste reduction, harmlessness and resource utilization.

[0003] The existing aerobic aeration treatment equipment cannot handle the solid debris trapped in the sewage during the sewage treatment process. It is necessary to perform an impurity filtration step before filtering the sewage, which is time-consuming and labor-intensive and has a relatively low treatment efficiency. To this end, we propose a sewage treatment device. Utility Model Content

Larger impurities can be quickly filtered through the intercepting filter and fall into the internal accumulation cylinder, thereby effectively separating large impurities and reducing the accumulation of garbage on the filter, which affects the filtering effect.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1-3 The embodiment of the utility model provides a technical solution: a sewage treatment device, comprising a primary filter box 1, the inner wall of the primary filter box 1 is fixedly connected with an interception bracket 2, the side wall of the interception bracket 2 is provided with a driving motor 3, the power output end of the driving motor 3 passes through the interception bracket 2 and is installed with an interception filter 4 for cleaning large debris, the bottom end of the primary filter box 1 is detachably plugged with a plug-in sealing frame 8, and the side wall of the plug-in sealing frame 8 is fixedly connected with a detachable filter 7;

[0025] A through-connecting pipe 9 is connected to the water outlet at the bottom end of the primary filter box 1, and the bottom end of the through-connecting pipe 9 is connected to the center of the top end of the aeration box 10. An air intake pipe 11 is connected to the side wall of one side of the aeration box 10, and the air intake pipe 11 passes through the aeration box 10 and is connected to the air inlet of the aeration pipe 12. An exhaust pipe 13 is connected to the end of the aeration box 10 away from the air intake pipe 11.

[0026] During use, when sewage is treated, the intercepting filter 4 inside the primary filter box 1 is first used to prevent the filter from being easily blocked after filtering impurities. Larger impurities can be quickly filtered through the intercepting filter 4 and fall into the internal accumulation cylinder, thereby effectively separating large impurities and reducing the accumulation of garbage on the filter, which affects the filtering effect.

[0027] As shown in the figure, the top of the primary filter box 1 is connected with an external water inlet pipe 6, and the external water inlet pipe 6 passes through one end of the primary filter box 1 and is connected with the water inlet 5.

[0028] When in use, sewage is transported through an external water inlet pipe 6 , and the flow rate of sewage is limited through the water inlet 5 so that the sewage can stably pass through the interception filter 4 .

[0029] As shown in the figure, a maintenance window 16 for inspecting and cleaning the internal filter structure is opened through the side wall of the primary filter box 1.

[0030] When in use, the filter mechanism inside the primary filter box 1 is inspected, maintained and cleaned through the inspection window 16 .

[0031] As shown in the figure, a drainage pipe 17 is opened through the bottom side wall of the aeration box 10.

[0032] When in use, sewage is discharged through the drainage pipe 17.

[0033] As shown in the figure, a motor compartment 14 is fixedly mounted on the bottom side wall of the aeration box 10 , and an aeration stirring rod 15 is mounted on one end of the power output end of the motor compartment 14 that passes through the aeration box 10 .

[0034] When in use, the aeration stirring rod 15 driven by the motor is used to assist the internal sewage in aeration treatment, thereby improving the efficiency of aeration treatment.

[0035] The working principle and use process of the utility model are as follows: the sewage first passes through the external water inlet pipe 6 through the primary filter box 1 and is discharged from the water inlet 5. The driving motor 3 on the side wall of the interception bracket 2 drives the interception filter 4 to circulate and contact the sewage discharged from the water inlet 5, filter and remove large-volume debris in the sewage and discharge it into a trash can. After filtering the large-volume debris, the sewage is further filtered through the detachable filter 7 plugged into the sealing frame 8 to filter the solid debris in the sewage, so that the content of solid debris in the sewage is reduced as much as possible, thereby facilitating the next step of aeration treatment, and then the primary filter 7 is further filtered. The control door at the bottom of the filter box 1 is opened, and the sewage is discharged into the aeration box 10 through the through-connecting pipe 9. The gas required for the corresponding sewage is transported to the aeration pipe 12 through the air inlet pipe 11, sprayed into the sewage for aeration operation, and then the excess gas is discharged through the exhaust pipe 13. During the aeration treatment process, the motor compartment 14 drives the aeration stirring rod 15 to stir the sewage, accelerate the aeration treatment of the sewage, and improve the treatment efficiency. The treated sewage is then discharged through the drainage pipe 17. During regular maintenance and cleaning of garbage in the internal filter, maintenance work is carried out by opening the maintenance window 16.
