Circulating marine aquaculture system based on membrane method microalgae cultivation

Abstract

The invention provides a circulating marine aquaculture system based on membrane method microalgae cultivation. The circulating marine aquaculture system based on membrane method microalgae cultivation comprises cultivation ponds, a foam separating device, cultivation tanks and a water collector. Rubber tubes are arranged inside the cultivation ponds, and optical fibers are arranged inside the rubber tubes and connected with a central control room through a distributed optical fiber temperature detector; the inside of every cultivation pond is provided with a communicating pipe, a circulating pipe, a drainage pipe and a return pipe, and the cultivation ponds are connected through the communicating pipes; every cultivation pond is also provided with an aerating device and connected with the water inlet and the water return inlet of the corresponding cultivation tank through the circulating pipe and the return pipe; every cultivation tank is provided with an emptying outlet and cultivation barrels and sequentially connected with the water collector through a water pump; the water collector is connected with the cultivation ponds, and the cultivation ponds are connected with the foam separating device. The circulating marine aquaculture system based on membrane method microalgae cultivation can achieve circulation of sea water.

Description

technical field [0001] The invention belongs to the technical field of circulating marine aquaculture, and in particular relates to a circulating marine aquaculture system based on membrane microalgae cultivation. Background technique [0002] In recent years, my country's mariculture industry has developed rapidly, and its aquaculture output has ranked first in the world for many years. However, the factors restricting mariculture and the problems of traditional aquaculture models have become increasingly prominent. Marine environmental pollution has seriously restricted the water used for mariculture, increasing the risk of aquaculture and reducing the risk of aquaculture. Due to the quality of aquatic products, the deterioration of the breeding environment, and the degradation of the germplasm of the breeding objects, the annual loss of mariculture due to disease problems exceeds 10 billion yuan. Concerned, reports of excessive drug residue detection in aquatic products hav...

AI Technical Summary

Problems solved by technology

The circulating water based on microalgae brings the excess nutrients from the cultivation of the first aquatic product to the second aquatic product, and serves as the bait of the second aquatic product, thus reducing water consumption and discharging "waste" It can be turned into beneficial nutrition, and the natural antibiotics secreted by microalgae can also be used to inhibit the occurrence of bacterial diseases in aquaculture aquatic products, and at the same time reduce the probability of infection of viral diseases, but there are vacancies in the detection of water quality and water temperature. The effect needs to be improved
