An open pond circulating aquaculture system

Abstract

The invention relates to an open pond recirculating aquaculture system. The open pond recirculating aquaculture system comprises an aquaculture pond, a water treatment unit and a water pump, wherein the water outlet of the aquaculture pond is connected with the water inlet of the water treatment unit, the water outlet of the water treatment unit is connected with the water inlet of the water pump, and the water outlet of the water pump is connected with the water inlet of the aquaculture pond; the water treatment unit comprises a wastewater pretreatment tank, an adsorption sedimentation tank, a biological tank and a water recycling tank which are sequentially connected; the water inlet of the water pump is connected with the water recycling tank; the aquaculture pond comprises an aquaculture room, an aeration water pushing device, a fence baffle A and a dirt collecting device A are arranged in the aquaculture room, the fence baffle A is arranged between the aeration water pushing device and the dirt collecting device A, the aeration water pushing device is arranged at the upper stream in the aquaculture room, and the fence baffle A is arranged at the down stream of the aquaculture room. The open pond recirculating aquaculture system occupies small area, effective aquaculture area is large, and aquaculture water can be effectively treated and recycled; and the aeration water pushing device in the aquaculture pond can realize aeration and oxygenation effects and also can promote flow of the aquaculture water and effective collection of feed residue and excrement.

Description

technical field [0001] The invention relates to the technical field of aquaculture equipment, in particular to an open pond circulating aquaculture system. Background technique [0002] With the rapid development of my country's social economy, the aquaculture industry has also entered a stage of rapid development. Pond fish farming is a traditional aquaculture method in my country. At present, traditional aquaculture ponds are facing a series of prominent contradictions and problems, such as the deterioration of aquaculture water resources, aging aquaculture facilities, lagging application of new technologies, frequent aquaculture diseases, and increasing hidden dangers of quality and safety. Contents of the invention [0003] The invention aims to provide an open pond circulating aquaculture system, which can remove residual bait and feces in the aquaculture water body, and reduce the pressure of aquaculture on the water resource environment. [0004] In order to achie...
