AI Technical Summary

Technical Problem

Existing media filters are difficult to backwash thoroughly, leading to impurities adhering to the media surface and clogging, reducing filtration efficiency. Furthermore, the process of replacing the media is cumbersome and complicated, increasing the difficulty and cost of operation.

Method used

The design incorporates a multi-layered filter box structure, a backwashing assembly, and a lifting assembly. It achieves uniform wastewater distribution through annular pipes and dispersion holes, ensures effective backwashing through its internal cavity and interface, and facilitates easy replacement of the filter box using hydraulic cylinders and fixing blocks.

Benefits of technology

It improves filtration efficiency, ensures water quality meets standards, reduces equipment maintenance costs, extends the service life of filter media, simplifies the media replacement process, and guarantees the purification effect of the aquaculture environment.

Abstract

The present disclosure relates to the technical field of sewage treatment equipment, and one embodiment of the present disclosure provides a sewage treatment device for aquaculture, which comprises a base and a shell, the shell is sleeved outside the base, a stand is arranged on the surface of the base, a layer plate is fixed on the stand, a filter assembly is arranged on the layer plate and the shell, a backwashing assembly is arranged in the stand, a lifting assembly is arranged between the stand and the shell, the filter assembly comprises a plurality of filter boxes, the filter boxes are placed on the layer plate, mesh holes are formed in the upper and lower surfaces of the filter boxes and the surface of the layer plate, and a water inlet pipe is arranged on the top of the shell. Through the above technical scheme, the technical problem that the medium filter in the prior art is difficult to backwash fully is solved, and in the long-term filtering process, a large amount of impurities such as residual feed, excrement, microorganisms and the like are attached to the surface of the medium, which gradually blocks the medium gap and reduces the filtering efficiency.
