Preparation method of biological magnetized material special for aquaculture filter material

Abstract

The invention discloses a preparation method of a biological magnetized special material for an aquaculture filter material in the technical field of preparation of special materials for aquaculture filter materials. The preparation method comprises the following steps: sequentially preparing an electrolytic layer, a filter membrane and a filter layer, and sequentially laying the prepared electrolytic layer, filter membrane and filter layer to prepare an electrolytic layer-filter membrane-filter layer-filter membrane; and clamping and assembling by using clamps. The electrolysis layer is arranged on the filter membrane and is clamped and assembled by using the clamp, such that the bubbles generated during the micro-electrolysis reaction of the electrolysis layer can be adsorbed on the filter membrane so as to promote the adsorption of the organic waste on the filter membrane, such that the organic waste has characteristics of alkalescence, good biological magnetization effect, strong reaction capacity and fast reaction speed in water, and the oxidation reaction is accelerated; meanwhile, the filter layer can improve the filtering effect of wastewater, bubbles generated by electrolysis can prevent a filtering material from being blocked, self-cleaning of the filter membrane can be achieved, and meanwhile the water quality purification effect is improved.

[0002] With the progress of society and the development of economy, aquaculture has entered more and more families and enterprises. Aquarium animals are generally cultivated in closed aquariums. Mechanical filtration or biological filtration is used to maintain water quality and remove excess bait, excrement, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, etc. The requirement of maintaining water quality is achieved through the adsorption of the filter material or the action of microorganisms on the filter material, but the filter material must be replaced regularly to maintain its performance, while biological filtration uses bacteria or microorganisms to perform a series of nitrogen fixation, dehydrogenation, and carbon fixation. , oxidation, etc. In practical applications, the electrolytic reactor needs to be washed frequently, and the micro-electrolytic materials also need to be replaced frequently. Moreover, the current micro-electrolytic materials are relatively simple, and the treatment effect is limited, which can easily cause the death of organisms. At the same time, if the long-term Soaking in waste water for a long time is prone to problems such as hardening and clogging, which will affect its service life. The filter materials generally used in the existing fish pond and fish tank water purification systems mainly include the following types:

[0003] (1) Ceramic filter material, which has a large specific gravity and small pore size, and most of them are closed-pore materials with weak adsorption and filtration functions;

[0004] (2) The biochemical ball made of plastic, the surface of the material is too smooth, which is not conducive to the growth of digestive bacteria;

[0005] (3) The sponge-based filter material is inconvenient to clean, and it is easy to increase the nitrite in the water, resulting in the death of fish. Therefore, we propose a biomagnetized aquaculture filter material preparation method
