Fish, prawn, algae, abalone and sea cucumber circulating water ecological comprehensive breeding system

Abstract

The invention relates to the technical field of aquaculture discharged water recycling, in particular to a fish, prawn, algae, abalone and sea cucumber circulating water ecological comprehensive breeding system. The system comprises a fish breeding pond, a prawn breeding pond, an ecological filtering pond, an algae, abalone and sea cucumber ecological breeding garden, a primary composite verticalflow artificial wetland, a secondary deep treatment composite vertical flow artificial wetland and a reservoir. The fish breeding pond and the prawn breeding pond are connected in parallel; breeding discharged water flows into the ecological filtering pond to be primarily purified, then sequentially flows through all stages of purification tanks so that residual bait and excrement generated by aquaculture can be effectively filtered away and dissolved nitrogen, phosphorus nutrients and organic matter in a water body can be deeply purified, and then the discharged water is circulated to the breeding ponds after being disinfected, sterilized and subjected to oxygen increase. By means of the step-by-step purification modules, the pollutant purification efficiency in the water body is improved, and fully-closed recycling of the aquaculture water body is achieved; meanwhile, plants planted by the purification modules and aquatic organisms bred by the purification modules have remarkable ecological benefits and economic benefits.

Description

technical field

[0001] The invention relates to the field of seawater ecological comprehensive cultivation, in particular to a circulating water ecological comprehensive cultivation system for fish, shrimp, algae, abalone and ginseng. Background technique

[0002] In May 2016, in order to further accelerate the transformation of the fishery development mode, adjust and optimize the industrial structure, and promote the transformation and upgrading of the fishery industry, the Ministry of Agriculture issued the "Guiding Opinions of the Ministry of Agriculture on Accelerating the Transformation of the Fishery Industry" On the one hand, it is necessary to actively develop healthy breeding models such as large-scale ecological breeding, industrialized circulating aquaculture, and three-dimensional breeding in marine ranches; focus on supporting the upgrading and transformation of environmental protection facilities and equipment such as wastewater treatment, recycled water, and c...
