A sea cucumber industrialized fully enclosed circulating aquaculture system

Abstract

A sea cucumber industrialized fully enclosed circulating aquaculture system belongs to the field of aquaculture technology, and it includes a special breeding pond and a water treatment system; the special cultivation pond is a round corner pond with a pot bottom shape at the bottom, and the drain is located at the lowest point in the center of the pond. At the bottom of the pool, 3-5 rings of porous bottom flushing pipes are laid horizontally; the water treatment system includes a slow-flow sedimentation tank, a pump pool, a water pump, a protein foam separator, a first-stage sewage interception biological purification tank, and a second-level degassing biological purification tank. , soda-water convection aeration pool and pipeline type ultraviolet sterilizer; the present invention designs a culture system suitable for sea cucumber industrialized fully enclosed circulating aquaculture according to the biological characteristics of sea cucumbers and culture water recycling technology. The new water supplement is less than 5%. Compared with the traditional water exchange or flowing water culture, the water saving can reach more than 95%. More importantly, the temperature control energy consumption in the breeding process is greatly reduced, and the energy saving is more than 70%.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of aquaculture, and in particular relates to a sea cucumber industrialized fully enclosed circulating aquaculture system. [0003] Background technique: [0004] Sea cucumber (Apostichopus japonicus), also known as sea cucumber, belongs to Echinodermata (Echinodermata) and Holothurioider (Holothurioider) in taxonomy. It is distributed in the intertidal zone of all oceans in the world to the sea area with a depth of 10,000 meters. It is a sediment-feeding marine animal. Sea cucumber has high nutritional and medicinal value, and is a high-end nutritional product that our people love very much. In recent years, with the growth of market consumption demand, the sea cucumber breeding industry has flourished, with an annual output value of more than 20 billion yuan. industry with the highest output value. [0005] Sea cucumber farming is mainly divided into near-shore bottom-seeding culture, intertidal zon...

Problems solved by technology

[0005] Sea cucumber farming is mainly divided into near-shore bottom-seeding culture, intertidal zone cofferdam culture, pond ecological culture and indoor factory high-density culture; due to factors such as industry, tourism, shipping industry, urban development and near-shore marine environment pollution Influenced by bottom-sowing farming near the shore, cofferdam farming in the intertidal zone, and ecological pond farming are showing a trend of shrinking, and indoor factory farming has the advantages of controllable farming environment, high breeding density, and short growth cycle, and the scale of farming is constantly expanding. However, the current factory farming mainly adopts temperature control and water exchange farming. The breeding process consumes a lot of energy and water, and requires regular pouring and flushing of the attachment base. The labor cost is very high, and a large amount of external drainage will easily lead to Seawater pollution and disease outbreaks and epidemics in the area have high risk of breeding, and it does not meet the national requirements for energy conservation, environmental protection, and the development of a circular water economy.
