Example 1:

the utility model provides a freshwater fish aquaculture all-in-one is batch production aquaculture all-in-one, and main preparation material is the A level PP panel of food level, and it has integrated cylinder microfiltration machine's machine and has strained unit 2, protein separator's foam filtration, ozone one-level germicidal treatment, one anaerobic digestion and filter, and three biochemical good oxygen fungus filter, ultraviolet ray second grade disinfection, air pump oxygenation.

The main treatment process flow comprises the following steps: the circulating water from the culture pond 300 has poor water quality; firstly, large-particle solid substances (impurities in water, excrement discharged by fish, residual feed, some oily substances in the feed, other dirt secreted by fish and the like) more than 30 microns in water are filtered out in a roller microfiltration mode by utilizing a physical mechanical filtration principle and are discharged; manual and automatic control is adopted in the aspect of electrical control of the link; the manual operation is mainly used for trial run and maintenance of equipment, and when the equipment is driven to a manual gear, an equipment button needing to be operated can be clicked on a touch screen to start/stop the equipment. In the automatic control gear; the equipment is realized in a mode of combining time and liquid level, namely, when the time is up, the equipment automatically runs; when the liquid level is up, the equipment runs, and when the time and the liquid level are both up, the equipment also runs; the length of time and the height of the liquid level; the culturists can set and adjust themselves according to the field condition and the cultivation condition; the whole link is organically combined with the whole all-in-one machine, and 80% of sewage in the water body can be basically discharged.

After the mechanical filtration is finished, the water body is subjected to primary anaerobic biochemical treatment, secondary trickling biochemical treatment, tertiary hairbrush biochemical treatment and quaternary suspension biochemical treatment, and the whole biochemical treatment process is divided into the four steps; the specific analysis is as follows: the first-stage biochemical treatment is mainly anaerobic, the water body enters the packing layer without aeration, and the direct contact with air is avoided, so the first-stage biochemical treatment is realized in the water body below the rotary drum of the micro-filter, and the link can add beneficial anaerobic strains into the water body, thereby improving the anaerobic effect; the water after anaerobic treatment is lifted to a second-stage trickling filtration biochemical link by a first-stage lifting pump; spreading the water body to form a trickling shape, uniformly scattering the trickling shape on a special trickling filter filler, aerating and oxygenating the bottom of the filler, and blowing off; not only can achieve the effect of trickling biochemistry, but also has the function of degassing, blows out toxic and harmful gases in the water body and increases the dissolved oxygen in the water body. After the biochemical trickle filtration, the water enters a hairbrush for biochemical filtration. The brush is a strip brush made of PET (polyethylene terephthalate) hair, and is mainly used for attaching most of decomposed bacteria to the surface of a material to reproduce and continuously decomposing organic matters in the digestive water in water treatment; the brush can also block part of the sewage in the water, such as the sewage which is not filtered out by microfiltration after the microfiltration treatment, and the sewage is digested and decomposed by attached beneficial digestive bacteria. The step needs continuous aeration and oxygenation, so that natural beneficial bacteria in the water body are bred and propagated, and a thick biochemical film is formed on the brush; the purpose of reducing ammonia nitrogen, nitrite, sulfide gas phosphate and the like in water is achieved. The water body enters a four-stage suspension biochemical link; the biochemical filtering mode is different from other biochemical filtering modes, K5 filler is used as a biological attachment medium, aeration and oxygenation are continuously needed, the filler is continuously rolled in water, and the filler is suspended in the water, and is continuously jumped up and down, rolled and collided; the biofilm on the filler in the water is continuously propagated and replaced, the aged biofilm is easy to fall off and is not blocked, and the filler is not blackened; after several layers of biochemical filtration in the stage; greatly improves the use efficiency of biochemistry, and combines biochemistry of different modes to ensure that the water quality condition reaches the standard and the biochemical effect is good.

After the protein separator finishes the treatment, the water body enters an ozone adsorption layer, namely a corallite filter layer; the main purpose of the layer is to absorb the redundant ozone and prolong the retention time of the ozone in the water body; because ozone is degraded into oxygen molecules after staying in a water body for a certain time; the adsorption layer adopts high-performance activated carbon and partial ceramsite as adsorption media; by a unique mechanical structure mode, the water flow mechanics principle is combined; residual ozone is adsorbed; the water body enters a final ultraviolet sterilization link, and in the link, secondary sterilization is realized in the integrated machine; the ultraviolet disinfection and sterilization is to use ultraviolet rays with proper wavelength to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of a microorganism organism, so that the growing cells and/or the regenerative cells are killed, and the sterilization and sterilization effects are achieved. The ultraviolet disinfection technology is based on modern epidemic prevention science, medicine and photodynamics, and utilizes specially designed UVC wave band ultraviolet light with high efficiency, high intensity and long service life to irradiate flowing water so as to directly kill various bacteria, viruses, parasites, algae and other pathogens in the water, thereby achieving the aim of disinfection. And after the water body is subjected to secondary sterilization and disinfection, the water reaching the standard is conveyed to each fish pond through a circulating water pump for recycling.
