Cyclic ecological fish culture equipment

Abstract

The invention provides cyclic ecological fish culture equipment which comprises a fishpond and a settling pond. The cyclic ecological fish culture equipment is characterized in that a drainage deviceis arranged in the fishpond which is connected with the settling pond through the drainage device, the drainage device comprises a plurality of first drainage pipes arranged on the inner wall of the fishpond and a second drainage pipe arranged at the center of the fishpond, and one ends, close to the bottom of the fishpond, of each first drainage pipe and the second drainage pipe are provided witha first water absorbing section and a second water absorbing section respectively; each first water absorbing section comprises a plurality of first through holes, the second water absorbing sectioncomprises a plurality of second through holes, diameter of the first through holes is greater than that of the second through holes, and the lowest water level of the fishpond is higher than the highest water level of the settling pond. A closed cyclic control model is adopted for the whole system, and no waste and wastewater are discharged from all ponds, so that zero environment pollution is realized, and the cyclic ecological fish culture equipment is environment-friendly and simple in structure.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a circular ecological fish farming equipment. Background technique [0002] A large amount of fish excrement remains in the fish pond. These excrement will make the aquaculture water contain a large amount of ammonia nitrogen, protein and other substances. These substances are not conducive to the growth of fish. If the content is too large, it will endanger the life of fish. Replace the water in the fish pond to ensure the water quality used in its growth environment. Most of the existing water in the fish ponds is driven by the motor and directly discharged, discarded and replaced with new water, or by spraying medicines in the fish ponds to dissolve the feces in the ponds to purify the water quality, but long-term spraying of medicines will not completely decompose these Excreta, also need to change the water quality regularly. These treatment methods cannot form a lon...
