Self-purifying-type small circulating pool system for germ plasma resource protection

Abstract

The invention relates to a self-purifying-type small circulating pool system for germ plasma resource protection, which is characterized in that the self-purifying-type small circulating pool system comprises an aquiculture water pool, a water guide pipe is arranged at the left rear part of the aquiculture water pool, the aquiculture water pool and a water isolating pool are communicated through the water guide pipe, floating plants are planted in the water isolating pool and a filter screen is arranged in the water guide pipe; a water isolating wall is arranged at the front of the water isolating pool, a group of ditches are arranged on the upper end surface of the water isolating wall, and the water isolating pool and an artificial underflow wetland pool at the front are communicated through the ditches; and an air-lift-type pipe is arranged at the front part of the artificial underflow wetland pool, the air-lift-type pipe consists of a perforated pipe, a water inlet pipe and an air stone, small holes are arranged in the side peripheral wall of the perforated pipe, the diameter of the small holes is smaller than the diameter of particles in the artificial underflow wetland pool, the side wall of the perforated pipe is connected with one end of the water inlet pipe, the artificial underflow wetland pool and the aquiculture water pool are communicated through the other end of the water inlet pipe, the air stone is arranged in the water inlet pipe and the air stone is connected with an external air pump. The water isolating pool, the artificial underflow wetland pool and the aquiculture water pool form an anticlockwise water circulating system.

Description

technical field [0001] The invention relates to a self-cleaning small circulation pool system for germplasm resource protection, which belongs to the technical field of aquatic equipment. Background technique [0002] Germplasm resource protection usually adopts natural breeding ponds, because natural breeding ponds are closer to natural ecosystems, natural ecosystems are conducive to the growth of aquatic animals, and the water quality is better, but natural breeding ponds are generally used for germplasm resource protection. The stocking density will be greatly reduced, which is not conducive to fish sampling, and the fish body is vulnerable to damage during the fishing process. The cement pool in the greenhouse is difficult to circulate due to the lack of self-purification ability. At the same time, due to the lack of competing organisms such as bacteria, it is easy to breed algae. Appropriate algae can increase the oxygen content of the water, but too much algae will det...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved in the present invention is: after the natural breeding pond is used for the protection of germplasm resources, the general stocking density will be greatly reduced, which is not conducive to the fishing and sampling of fish, and in the process of fishing, the fish body is easily damaged
