Disclosure of Invention

Aiming at the defects of the prior art, the invention aims to provide the following steps: provides a fish ecological cycle culture water treatment system, which greatly reduces the floor area of a water treatment workshop under the condition of shortage of a current culture site.

The first purpose of the invention is realized by the following technical scheme:

the utility model provides a fish ecological cycle breeds water processing system, includes the primary filter, albumen separator, biological filter, dissolved oxygen ware, the ultraviolet ray sterilizer that adopt the pipeline intercommunication in proper order, has laid brush formula biofilm carrier and aeration equipment in the biological filter, is provided with the water pump on the pipeline, the biological filter has into water end and goes out the water end, is provided with a plurality of longitudinal baffles in the end of intaking and going out between the water end of biological filter side by side, and the bottom mounting in biological filter of longitudinal baffle is the diapire of biological filter, and a side of longitudinal baffle is fixed with the lateral wall of biological filter for the flowing water passageway between the end of intaking and the play water end of biological filter is the S type in the horizontal direction.

By adopting the scheme, under the driving action of the water pump, the water to be treated pumped from the fish pond flows out of the filter tank, the protein separator, the biological filter tank, the oxygen dissolving device and the ultraviolet sterilizer in sequence and then flows back to the fish pond. During the period, water entering the biological filter from the water inlet end of the biological filter flows in an S shape in the horizontal direction, and then leaves the biological filter from the water outlet end of the biological filter. Under the prerequisite that does not change the biological filter volume, prolonged the flow time of water in the biological filter greatly, prolonged the contact time of water and brush formula biofilm carrier for the fungus class on the brush formula biofilm carrier can be more abundant decompose the harmful substance in the aquatic, improve water treatment quality. The arrangement of the biological filter can greatly reduce the floor area of a water treatment workshop under the condition of shortage of the current culture field.

The invention is further configured to: a plurality of transverse clapboards are arranged in the water flowing channel, the water flowing channel is divided into a plurality of biological treatment areas by the transverse clapboards, and brush type biological fillers and aeration devices are uniformly distributed in all the treatment areas; the adjacent transverse partition plates are different in height, and one biological treatment area and the biological treatment areas on the two sides are respectively communicated with the top and the bottom, so that water flow in the water flow channel is S-shaped in the vertical direction.

Through adopting above-mentioned scheme, through setting up the horizontal baffle of height difference for the water that gets into in the biological filter also is the S type and flows in vertical direction. On one hand, the water treatment device can be matched with the S-shaped flow in the horizontal direction, so that the flow time of water in the biological filter is further prolonged, and the water treatment quality is improved; on the other hand, the water flow up-and-down stirring effect can be achieved in the biological filter, so that the water in the biological filter is distributed more uniformly, and the consistency of water treatment is improved.
