Water treatment system and method for aquaculture

Abstract

The invention provides a water treatment system for aquaculture. The system comprises a floating platform, an aquaculture water tank, a circulating water pump, a filtering and separating device, fans,a water tank bottom purging system and a biochemical filtering pool, wherein the biochemical filtering pool is connected with the filtering and separating device through a pipeline; the aquaculture water tank is embedded in the floating platform; the circulating water pump comprises a deepwater submersible pump and a surface water submersible pump; the filtering and separating device comprises amicrofiltration machine and a protein separator, the microfiltration machine is connected with the deepwater submersible pump through a pipeline, the protein separator is connected with the surface water submersible pump through a pipeline, and the fans are connected with the water tank bottom purging system in the aquaculture water tank, the protein separator and the biochemical filtering pool through pipelines respectively. According to the water treatment system for aquaculture, aquaculture water and pond water are separated, the aquaculture system is subjected to life support treatment with circulating water, the aquaculture water is purified and flows into a pond for secondary purification, then the water is circulated in the aquaculture water tank, so that water resource is recycled,the purification effect is ideal, and dynamic balance of water is realized.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an aquaculture water treatment system and a treatment method. Background technique [0002] At present, my country's aquaculture is developing towards high density, intensification, and scale. However, due to the lag of corresponding technology, high-density and intensive aquaculture often lead to increased eutrophication, reduced dissolved oxygen, and harmful substances in ponds. Exceeding the standard, fish diseases occur frequently, causing huge economic losses to the aquaculture industry. If there is loss of bait, the bait deposited on the bottom of the pond will deteriorate the local environment of the bottom during the process of decay and decomposition, which will affect the water quality, poison the breeding objects, bring great hidden dangers and threats to the health of the breeding objects, and cause the breeding The environment is harsh, and it is gett...
