Industrial culture system of pond

Abstract

The invention discloses an industrial culture system of a pond. The industrial culture system is installed in the pond and is composed of a water pushing aeration unit, a culture feeding unit, a dirt collecting and discharging unit and an ecological purifying unit. The water pushing aeration unit comprises an aeration device, an air blower, a baffle and an air pipe. The air blower is arranged above the water surface, the aeration device is arranged underwater, the air pipe is connected with the air blower and the aeration device, and the baffle is obliquely arranged above the aeration device. A solid-liquid separation device is arranged in the dirt collecting and discharging unit. The ecological purifying unit comprises a large pond water body and an artificial floating island. Aquatic animals are bred in the pond, aquatic plants are planted in the pond, and plants are planted on the artificial floating island. The solid-liquid separation device is used for replacing a solid waste self precipitation separation mode, so that the dirt collecting and discharging efficiency of the system is greatly improved, the solid waste removal rate of the culture pond water body reaches 80%, the water quality of the culture pond is greatly improved, the total culture quantity is increased, the quality of culture varieties is improved, and meanwhile the work time of the aeration device is shortened.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a pond industrialized aquaculture system. Background technique [0002] In traditional aquaculture ponds, plankton are producers, filter-feeding fish are consumers, and microorganisms in the water are decomposers. The aquaculture water body is not only the living place of the aquaculture object, but also the decomposition place of feces and residual bait, as well as the cultivation pool of plankton. This "three pools in one" farming method is likely to cause an ecological imbalance among "consumers, producers and decomposers". There is too little water for separating or degrading the metabolites of the cultured objects, usually especially in the high-density culture mode and rapid growth period, and the water quality is often adjusted by changing the water regularly. In addition, the "three ponds in one" farming model also increases the difficulty of management. There is ...

AI Technical Summary

Problems solved by technology

[0018] 2. Due to poor sewage collection and discharge, the dissolved oxygen in the culture pond is low, which affects the decline in the total production of the culture and the quality of the cultured species;

[0019] 3. In addition, it also causes the aeration device (such as a fan) to work 24 hours a day, with high energy consumption and easy failure
