Closed-type constant-temperature multi-layer water circulation turtle cultivation system

Abstract

The invention discloses a closed-type constant-temperature multi-layer water circulation turtle cultivation system which comprises a multilayer turtle cultivation pool devices, a cultivation water environment adjusting device, an indoor air environment adjusting device and a cultivation system operation control device, wherein the multilayer turtle cultivation pool device comprises a plurality of turtle cultivation pools, circulating water return pipes, circulating water outlet branch pipes and main circulating water outlet pipes, primary solid liquid precipitation devices, blow-down valves and pollution discharge blow-down pipes; the cultivation water environment adjusting device comprises a solid-liquid separator, a blow-down valve, a sterilizer, a protein separator, a biological filtering device or tank, a circulating pump and a water heating device; and the indoor air environment adjusting device comprises an air heating device, an air oxygenating device and an insulation building. According to the closed type constant-temperature multi-layer water circulation turtle cultivation system, turtle cultivation environments can be comprehensively controlled, the land, the water and the energy are saved, an optimal ecological environment suitable for turtles to rapidly grow is established, turtle cultivation is free of drugs, and healthy and safe food sanitation requirements are met.

Description

technical field [0001] The invention relates to a multi-layer turtle breeding pond device, in particular to a closed constant-temperature multi-layer water circulation turtle breeding system for industrialized turtle breeding. Background technique [0002] Turtles are temperature-changing aquatic animals, and the most suitable water temperature for growth is around 30°C. Using artificial facilities to adjust the breeding water temperature to about 30°C can make the turtles feed and grow rapidly throughout the year, and the cultivation period is shortened from 4-5 years to about 1 year. In recent years, the industrialized temperature-controlled breeding of turtles based on water exchange has developed rapidly, with an annual output of more than 200,000 tons in 2011. At present, the scale and output of industrialized tortoise and turtle breeding are still expanding, but this traditional breeding model brings about high water consumption, high energy consumption, environmental...

AI Technical Summary

Problems solved by technology

At present, the scale and output of industrialized tortoise and turtle breeding are still expanding, but this traditional farming model brings about high water consumption, high energy consumption, environmental pollution, drug abuse, etc., which consume a lot of resources and endanger the environment and food. The problem of quality and safety has not been well resolved, which seriously hinders the healthy and sustainable development of the turtle breeding industry
