[0002] In the practice of aquaculture, the effective treatment and purification of sewage are the core links to maintain water quality safety and promote the healthy growth of aquaculture organisms. Given this importance, industry experts have been continuously exploring and innovating to address the limitations of existing technologies. Taking the Chinese patent CN218931881U as an example, this patent proposes a sewage treatment device for aquaculture systems.
