Two-channel aquaculture pond sewage discharge system

Technical Field

The utility model relates to a cultured equipment field, concretely relates to binary channels aquaculture pond drainage.

Background

The industrial culture and the high-density intensive culture are the main modes of the current aquaculture, especially when the shrimps and crabs are used as culture objects, along with the increasing of the feed feeding amount, the shrimps and crabs can not only generate more and more small wastes such as residual baits, excrement and the like in the growth process, but also generate a large amount of large organic wastes such as shrimp shells, crab shells and dead shrimps and crabs and the like, and the wastes can be discharged in time to cause the rapid increase of toxic and harmful substances such as ammonia nitrogen, nitrite, hydrogen sulfide and the like in the culture water body, so that the aquatic animals are poisoned to cause morbidity and death in severe cases. The existing pond sewage draining port is provided with a filtering hole too thin to prevent fishes and shrimps from escaping, so that large dirt such as dead fishes, shrimps, crabs and the like is remained in the pond to cause pollution, and the water quality is poor and the fishes and shrimps are attacked.

Therefore, various pollutants in the aquaculture water body need to be removed timely and efficiently so as to avoid the pollution of the pollutants on the aquaculture water body and keep the aquaculture pond with good water quality. In order to solve the above problems, we have devised a sewerage system suitable for use in an aquatic animal aquaculture pond.
