Circulating water culture system

Abstract

The invention relates to a circulating water culture system, in particular to a circulating water culture system suitable for an outdoor large-area culture pond. The circulating water culture system comprises a culture pond and a solid dirt separator, a protein separator, a biological purification tank, an aeration tank and an ultraviolet sterilization tank sequentially connected through a water pipe, wherein the culture pond is arranged outdoors; and the solid dirt separator, the protein separator, the biological purification tank, the aeration tank and the ultraviolet sterilization tank are arranged indoors. Water treated by the system can reach the culture standard, and the system has a simple structure and is easy to be grasped by a common culturist; and moreover, an artesian manner is adopted in a biological filter, a carbon dioxide removing tank, the ultraviolet sterilization tank and a reflow pond, energy consumption is reduced and cost is lowered.

Description

【Technical field】 [0001] The invention relates to a circulating aquaculture system, in particular to a circulating aquaculture system suitable for outdoor large-area aquaculture ponds. 【Background technique】 [0002] With the further refinement of aquaculture management technology, in order to raise fish and shrimp well, water must be raised first. The role of water quality control in aquaculture is becoming more and more important. Farmers need a system to reduce or remove water that is harmful to aquaculture. Substances, such as residual bait, feces, ammonia nitrogen, nitrite nitrogen, harmful microorganisms, etc., and can achieve the purpose of energy saving and environmental protection, so as to reduce disease, improve breeding success rate and reduce costs. The circulating water system can basically meet the above requirements. The current circulating aquaculture system is mainly closed, which can make the breeding environment free from external water sources and climat...

AI Technical Summary

Problems solved by technology

The circulating water system can basically meet the above requirements. The current circulating aquaculture system is mainly closed, which can make the breeding environment free from external water sources and climate constraints, but the closed circulating aquaculture is mainly based on factory farming, and the system cost High, professional operation, not suitable for large-scale outdoor aquaculture ponds in my country
