[0002] In the field of marine aquaculture, the cleaning of wastewater grids is a key link to maintain the efficient operation of the aquaculture wastewater treatment system, and its state is directly related to the stability of the aquaculture environment and the safety of the subsequent treatment equipment. Marine aquaculture wastewater often contains a large amount of organic matter such as leftover feed, feces, algae, and fish scales and shrimp shells, and has a high salt content. This makes the grid not only easy to be clogged with dirt, but also the retained residues are highly corrosive, so regular cleaning with a grid processing device is required to effectively ensure the smooth operation of the entire treatment system.

[0003] Although the existing grid processing device can quickly remove algae wrapped on the surface of the grid, large pieces of feed in marine aquaculture wastewater are easily stuck in the gaps between the grid bars. The existing device relies on a brush for cleaning, but the brush cannot effectively apply force to the stuck feed in the gap, causing these large pieces of feed to remain in the gap for a long time. This not only reduces the wastewater flow cross-section and increases the water head loss, but also causes bacteria to grow due to feed rotting, which adversely affects the service life and processing efficiency of the grid and subsequent treatment equipment. Therefore, we propose a marine aquaculture wastewater grid processing device. SUMMARY
