Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment devices, and in particular to a sewage treatment device with a step-by-step filtration structure. Background Technology

[0002] Wastewater treatment equipment is a device and system used to remove pollutants from wastewater, aiming to protect the environment and human health by removing large particulate matter and suspended solids from wastewater. Commonly used equipment includes bar screens, screens, and grit chambers. The design and selection of wastewater treatment equipment depends on the nature of the wastewater, the scale of treatment, and the end use. Modern wastewater treatment technology is constantly developing, and many new types of wastewater treatment equipment are under development to improve treatment efficiency and reduce energy consumption.

[0003] For example, the wastewater treatment device with a step-by-step filtration structure disclosed in the authorization announcement number CN220665099U, although it is achieved by installing the first partition plate inside the filter box on one side, specifically in the middle position, and then the extension rod working to drive the extension and retraction of the second partition plate, allowing the second partition plate to first abut against the other side inside the filter box, and with the rubber ring fixing it in place, achieving a sealing and fixing effect, so after the wastewater enters at the inlet, it can first pass through the upper area, then through the first filter screen plate, filter cloth and second filter screen plate for filtration, and then after the extension rod retracts, the second partition plate can retract towards the first partition plate, and then the wastewater will reach the lower area of ​​the filter box, and be filtered again through the activated carbon layer, thus completing the step-by-step filtration work well, in actual use, the dirt on the filter screen still needs to be cleaned manually, which makes it relatively troublesome to use. Long-term use can easily cause the filter screen surface to become clogged, thereby reducing the effectiveness of the device. Therefore, the above problems need to be solved. Utility Model Content
