A high-efficiency and energy-saving factory double-circulation breeding system

Abstract

The invention relates to a high-efficient and energy-saving type industrialized double-circulating breeding system. The breeding system consists of a breeding pond, an inner circulating system and an outer circulating system, wherein the inner circulating system and the outer circulating system are arranged on the periphery of the breeding pond, the inner circulating system comprises a gas stripping pond, a combination type gas stripping device is arranged in a gas pond, a gas stripping pond water inlet and a gas stripping pond water outlet are respectively arranged on the bottoms of the pond walls at the boundary parts of the breeding pond and the gas stripping pond, the water-out direction of the gas stripping pond water outlet is the same with the water flow direction of the breeding pond, the outer circulating system sequentially comprises a primary sedimentation pond, a secondary sedimentation pond, a mechanical filtering pond, a water collection pond, a shunting channel, a biologic filtering pond, a sand filtering pond and an infrared sterilizing and water collecting integrated pond, and the primary sedimentation pond is arranged outside the breeding pond. The breeding system has the advantages of low engineering cost, high water treatment efficiency, low energy consumption during running, low running cost, convenience in operation, low failure rate, high dissolved oxygen content in the breeding pond, capability of meeting high-density breeding and the like, and has great application and popularization prospects.

Description

technical field [0001] The invention belongs to the field of facility fishery, and specifically relates to an industrial aquaculture system that can be used for various aquaculture species such as fish and sea treasures, and in particular to an efficient and energy-saving industrialized double-circulation aquaculture system. Background technique [0002] In recent years, the factory farming model has developed rapidly, and the cultured species mainly include a series of famous and high-quality species such as sea and freshwater fish, shrimp and crab, shellfish and sea treasures. The main methods of factory farming include artesian water factory farming, semi-closed factory farming and fully closed factory farming. Although artesian water farming and semi-closed factory farming have relatively low farming costs, their impact on water The utilization rate is low, the waste phenomenon is relatively serious, the technical content is low, and the discharge of aquaculture wastewat...

Problems solved by technology

[0004] In order to overcome the shortcomings of the existing double circulation system for fish farming, the technical problem to be solved by the present invention is to provide a low investment, low operating cost, convenient operation and management that can be used for sea and fresh water fish, shrimps, crabs, shellfish and marine treasures. The factory farming system of a series of famous and high-quality species, such as fish, removes the obstacles of factory circulating aquaculture, improves the benefits of farming, and is conducive to the healthy and sustainable development of the aquaculture industry. It not only solves the problem of water purification and recycling, but also Enhanced air lifting effect
