Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment interception device. Background Art

[0002] Wastewater treatment refers to the process of removing harmful substances and pollutants from wastewater generated by cities, industries, etc. through a series of physical, chemical and biological treatment processes, and converting it into water resources that can be safely discharged or reused. The process usually includes primary treatment, secondary treatment and tertiary treatment. The primary treatment mainly uses physical methods to remove large particles and other debris in the sewage. This physical method usually uses a filtering and interception device to filter and intercept large particles and other debris.

[0003] After searching, the authorization announcement number CN215585585U and the authorization announcement date 2022.01.21 disclose an interception device for sewage treatment, which relates to the technical field of sewage treatment devices. The interception device for sewage treatment includes a channel, a support frame is arranged at the top of the channel, and an interception component for intercepting garbage is arranged on the support frame. The interception component includes an interception device symmetrically arranged on the inner wall of the channel and a lifting component for lifting the interception device. Two limit plates are symmetrically arranged on both sides of the channel, and a slide groove adapted to the interception device is provided on the limit plate. The interception device includes an interception box, one side of the interception box is open, and a plurality of through holes are evenly provided on the interception box. The utility model can quickly lift the interception box from the water through the cooperation of the lifting assembly and the interception device, so as to facilitate the staff to clean up the garbage. The limit strip is set so that the interception plate can be quickly removed from the interception box, which is convenient for cleaning the interception plate, thereby improving the interception effect.

[0004] However, the existing technology has the following shortcomings:

[0005] 1. When the above-mentioned interception device for sewage treatment is in use, the interception box can be quickly raised from the water through the cooperation between the lifting assembly and the interception device, so as to facilitate the staff to clean up the garbage. However, in actual operation, the operator needs to manually remove the debris in the interception device, resulting in a high labor intensity when removing the debris in the interception device;

[0006] 2. When the above-mentioned intercepting device for sewage treatment is in use, large particles and other debris in the sewage can be intercepted and filtered through the intercepting plate. However, in actual use, the intercepted large particles and other debris will adhere to the surface of the intercepting plate and block the filter holes in the intercepting plate, resulting in a reduction in the sewage treatment volume.
