Water circulation culture system

Abstract

The invention relates to the technical field of aquaculture, and provides a water circulation culture system. The water circulation culture system comprises a culture pond, an automatic controller, a primary filter device, a water temperature regulation device, a disinfection tank, a water quality regulation tank and a secondary filter device, wherein the primary filter device, the water temperature regulation device, the disinfection tank, the water quality regulation tank and the secondary filter device are communicated with the culture pond in sequence through water pipes on which a power device for providing water flow power is arranged, the primary filter device is connected with a water outlet of the culture pond, the secondary filter device is connected with a water inlet of the culture pond, and the primary filter device and the secondary filter device are both communicated with a slurry tank. By means of the water circulation culture system, culture water can be recycled, so that the water consumption is significantly reduced, and it is avoided that discharge of culture wastewater causes environmental pollution; culture residues can be effectively utilized, and the purification effect is good; the acidity and alkalinity can be regulated to be balanced to obtain good-quality culture water, so that a good growth environment is provided for aquaculture animals, the morbidity rate and the death rate are reduced, and the culture cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a water circulation culture system. Background technique [0002] my country is a big fishery country. China's aquatic product output ranks first in the world, and it is the only country in the world where aquaculture output exceeds fishing output. Aquaculture is usually cultivated in aquaculture ponds, and the water in the aquaculture ponds cannot be effectively circulated due to its closedness. Under such an environment, the solid residues and excreta of aquaculture products cannot be discharged, resulting in the water in the aquaculture ponds changing. Poor, pH imbalance, bacteria in the water increase, if not removed in time, the water in the pool will be seriously polluted, seriously endangering the growth of aquaculture, and even cause the death of aquaculture in the pool for a long time, bringing great harm to the culture Loss. In the prior art, there are many defect...

Problems solved by technology

Aquaculture is usually cultivated in aquaculture ponds, and the water in the aquaculture ponds cannot be effectively circulated due to its closedness. In this environment, the solid residues and excreta of aquaculture products cannot be discharged, resulting in the water in the aquaculture ponds changing. Poor, pH imbalance, bacteria in the water increase, if not removed in time, the water in the pool will be seriously polluted, seriously endangering the growth of aquaculture, and even lead to the death of aquaculture in the pool for a long time, bringing great harm to the culture Loss

There are many defects in the aquaculture water circulation and purification system in the prior art, the removal effect of bacteria and particulate matter in the water body is not obvious, and the water quality and temperature cannot be well adjusted
