Embodiment Construction
[0013] A double-circulation zero-emission healthy breeding system, the external circulation system includes a water inlet 15, a culture pond 11, a drainage ditch 12, an ecological purification pond 13, and an ecological ditch 14; the water inlet, the culture pond, and the drainage ditch , ecological purification ponds, and ecological ditches are connected in sequence, and the water inlet channel is connected with the ecological ditch to form an external circulation system; it is characterized in that: it also includes an internal circulation system, and the internal circulation system includes the cultivation pond in the external circulation system and the cultivation pond and the cultivation pond. The pool is connected to form the active filter chamber 21 of the circulation system; the internal circulation passes through the active filter chamber to filter the impurities (food residues, animal manure, etc.) in the culture pond water and increase the oxygen content of the water ...

The invention discloses a double-circulation zero-emission healthy breeding system which can reduce waste of water resources and save energy. The double-circulation zero-emission healthy breeding system comprises an external circulation system, wherein the external circulation system comprises a water inlet ditch, a breeding pool, a water draining ditch, an ecological purifying pool and an ecological ditch, wherein the water inlet ditch, the breeding pool, the water draining ditch, the ecological purifying pool and the ecological ditch are connected in sequence, and the water inlet ditch and the ecological ditch are connected into the external circulation system. The double-circulation zero-emission healthy breeding system is characterized by also comprising an internal circulation system, wherein the internal circulation system comprises a breeding pool in the external circulation system and an active filtering chamber connected with the breeding pool into the circulation system. The double-circulation zero-emission healthy breeding system has the advantages of solving the water quality problem caused by feeding through external circulation, removing impurities in water through the internal circulation system, realizing a large amount of circulating water and a small amount of changed water, enabling the ecological environment of the breeding water to be small, and the like.
Description
technical field [0001] The invention relates to a breeding system, in particular to a double-cycle zero-emission healthy breeding system. Background technique [0002] my country is a big aquaculture country. In 2008, the output of aquaculture was 34.1282 million tons. In 2008, the total area of aquaculture in the country was 6.5499 million hectares, of which the area of ponds and industrialized aquaculture was about 2.4955 million hectares, with an output of 6.0087 million tons; industrialized aquaculture was nearly 30 million cubic, with an output of 216,900 tons. Eels and prawns, which are intensively cultured, have become important cultured species and foreign exchange earning products for export in my country. In terms of eel farming, in 2008, the national aquaculture output was 205,300 tons, while the output in our province was about 95,000 tons. As far as vannamei is concerned, the national seawater output exceeds 720,000 tons and freshwater output exceeds 520,00...
