Field of the Invention The present invention relates to a circulating-filtration type collecting device, and more particularly, to a circulating-filtration type collecting device connected to a aquaculture tank for collecting breeding water and circulating and filtering the collected breeding water to the aqua- will be.

In general, there are fish farming systems, water farming farms, cage farming farms, circulation farming farms, and fish farming facilities vary in structure, form and size depending on the type, purpose and method of meat to be farmed.

Circulating aquaculture is a large-scale method used to grow ornamental fish in aquariums and homes. It aims to grow many aquatic animals in small quantities by increasing dissolved oxygen while eliminating harmful substances in the water. Ammonia and organic matter excreted by aquaculture organisms are decomposed into minerals by the action of germs in the water and the filtration layer, and ammonia and nitrite, which are harmful to fish, are converted into nitrate which is less toxic. In the case of a small ornamental water tank, the dust, excrement and food waste in the water may be filtered into the sand or gravel layer in the water tank, but in large-scale aquaculture facilities, they are separated and separated from the filtration tank. If you use a filter in the tank, you may need to wash it occasionally to improve its filtration ability because it may clog the filter layer if it is used for a long time or if it contains too many fish. The circulation of water is by the pump and oxygen is supplied to accelerate the decomposition of the organic matter, so it gives up by the pump.
