Embodiment Construction

[0018] The present invention is described below based on examples, but the present invention is not limited to these examples.

[0019] A double circulation seawater prawn integrated culture system, such as figure 1 As shown, it includes: shrimp culture ponds, sludge treatment ponds, primary surface flow constructed wetlands, secondary composite vertical flow constructed wetlands, seaweed biofilters and reservoirs, shrimp cultivation ponds, sludge treatment ponds, primary The surface flow constructed wetland, the secondary composite vertical flow constructed wetland and the reservoir are connected in sequence, the reservoir is connected to the prawn breeding pond, and the shellfish biofilter is connected in parallel with the primary surface flow constructed wetland and the secondary composite vertical flow constructed wetland. That is, the shellfish biofilter is respectively connected with the sludge treatment tank and the water storage tank, a valve is set between the shellfi...

Abstract

The invention relates to the technical field of seawater ecological breeding, in particular to a double-circulation seawater prawn comprehensive breeding system. The system comprises a prawn breedingpond, a sludge treatment tank, a first-stage surface flow constructed wetland, a second-stage composite vertical flow constructed wetland, a shellfish and alga biological filter and a reservoir, wherein the prawn breeding pond, the sludge treatment pond, the first-stage surface flow constructed wetland, the second-stage composite vertical flow constructed wetland and the reservoir are sequentiallycommunicated; the shellfish and alga biological filter is in parallel connection with the first-stage surface flow constructed wetland and the second-stage composite vertical flow constructed wetland, and is also in serial connection with the first-stage surface flow constructed wetland and the second-stage composite vertical flow constructed wetland; secondary deep treatment can be carried out when necessary, economical tidal flat crabs and tidal flat fishes are bred in the sludge treatment tank, and filter-feeding fishes, shellfishes and snails are bred in the first-stage surface flow constructed wetland. The system can effectively filter away residual bait, excrement and the like in prawn breeding discharged water, can purify nitrogen, phosphorus and other pollutants, has good ecological benefits, is low in overall energy consumption and saves energy.

Description

technical field [0001] The invention relates to the technical field of seawater ecological cultivation, in particular to a double-circulation seawater prawn comprehensive cultivation system. Background technique [0002] The main pollutants in my country's offshore and marine fishery waters are inorganic nitrogen and phosphate, among which nitrogen and phosphorus are regarded as one of the main factors that cause eutrophication of water bodies and even red tides and brown tides. The discharge of aquaculture drainage is relatively small compared with agricultural wastewater, urban sewage and industrial wastewater, but the direct discharge of aquaculture discharge water will also aggravate the deterioration of water quality in rivers, lakes and offshore waters. my country is the only country in the world where the amount of aquaculture is higher than the amount of catch. Since the 1980s, the scale of aquaculture has continued to expand, and the scale of seawater factory aquacu...
