Abstract

The invention provides a biological filter for culturing crabs in hydrogen-rich water, and relates to the technical field of hydrogen-rich water culture. The biological filter for the hydrogen-rich water crab culture comprises a filter body communicated with a crab culture box, wherein the inner wall of the filter body is fixedly connected with a lower bearing plate and an upper baffle plate respectively, a water inlet of the filter body is positioned below the lower bearing plate, and a filler layer is filled between the lower bearing plate and the upper baffle plate. By adopting the aeration pipe, the mixed gas rich in oxyhydrogen is used as a gas source for aeration, so that the contact of organic matters and oxygen in sewage is accelerated, the degradation and oxidation of the organic matters are promoted, meanwhile, part of harmful free radicals in the sewage can be removed by hydrogen, pathogenic bacteria or conditional pathogenic bacteria are inhibited, and the treated water is reused in a culture system (used as supplementing water), so that a certain hydrogen-rich environment is provided for crabs, the potential hydrogen-rich effect transmission is realized, and the subsequent blue crab culture effect is improved.
