[0066] as Figure 1 and Figure 2 Shown, a schematic diagram of the planar structure and a schematic diagram of the profile structure of the first embodiment of the present invention, an old fish pond transformed into a grass symbiotic ecological fishing pond disclosed in the present invention, the fish pond area of 4200m 2 It is 80m long, 52.5m wide and has an average water depth of 2m, which is a mixed pond for grass carp, silver carp and silver carp. The fish pond has not been dredged for a long time, and the problems of serious overuse of bait and insufficient hydrodynamic power have led to a serious outbreak of blue-green algae in the fish pond, and the water quality of the fish pond is inferior to five categories. The adjacent river to this fish pond is a first-class tributary of the left bank of the upper reaches of the Yangtze River. The pond's clearing of wastewater, daily water change, and overflow during the rainy season cause the tailwater of the pond to be discharged di...

[0083] as Figure 3 、 Figure 4 and Figure 5 Shown, a schematic diagram of the planar structure of a second embodiment of the present invention, a schematic diagram of the cross-sectional structure and a large sample of the infiltration enclosure, the fishing pond area of 6600m 2 With a length of 120 m, a width of 55 m and an average water depth of 2 m, it is a new fishing pond, which mainly breeds lower fish.

[0084]The entire fishing pond 1 is divided into three areas with 2 infiltration enclosures 2, the left and right sides are ecological zones 4, the middle is fishery aquaculture area 5, and the ratio of ecological zone 4 to fishery aquaculture area 5 is 1:4. The water depth is 2.0 m in ecological zone 4 and 2.7 m in fishery and aquaculture area 5. The topography of each zone was shaped so that the bottom of each zone formed an elevation difference, and the bottom elevation of the fishery and aquaculture area 5 was lower than the bottom elevation of the ecological zone 4, and ...

[0103] as Figure 6 、 Figure 7 and Figure 8 Shown, a schematic diagram of the planar structure of the third embodiment of the present invention, a schematic diagram of the cross-sectional structure and a large sample of the osmotic enclosure, the fish pond area of 12800m 2It is 160m long, 80m wide and has an average water depth of 2m, making it a traditional farmed shrimp pond. The pond itself has some submerged plants for shrimp to eat, but it is also necessary to sprinkle feed on a daily basis to increase the production of shrimp, and the effluent quality of the shrimp pond is inferior to five categories. The entire pond was reconstructed and divided into two areas with infiltration enclosure 2, the left side is the ecological zone 4, the right side is the fishery breeding area 5, and the ratio of the ecological area 4 to the fishery aquaculture area 5 is 1:9. The water depth of ecological zone 4 is 1.5 m, and the water depth of fishery and aquaculture area 5 is 2.5 m. The terrai...

Abstract

The invention relates to a fish-grass symbiotic ecological fish pond and a fishery breeding sewage treatment method, one or more permeable enclosures are arranged in the ecological fish pond, so that at least two subareas are formed in the ecological fish pond; the interior of the permeation enclosure is of a hollow structure and is filled with filler; a plurality of holes are formed in the outer surface of the permeation enclosure; the top end of the permeable enclosure is higher than the normal water level of the ecological pond; and a waterproof foundation structure is arranged below the permeable enclosure. The system is simple in structure, low in energy consumption and easy to operate and maintain, an eco-friendly mode is adopted for construction, feeding of feed can be reduced, and resources are saved; the tail water purification device has a good landscape effect while purifying tail water; a good habitat structure is formed by the permeation enclosure, a good foraging, refuge, inhabiting and breeding place is provided for aquatic animals in water, and the stability of an ecological system in the whole ecological fish pond can be maintained.

Description

Technical field [0001] The present invention belongs to the aquaculture industry tailwater ecological treatment and restoration field, in particular to a kind of fish and grass symbiotic ecological fishing pond and fishery aquaculture sewage treatment method, having fishery economic output, dynamic zeroing of pollutants and tailwater discharge function. Background [0002] In recent years, aquaculture as one of the industries of national economic development, has great significance for the national economy and human development, but with the continuous progress of human society, the rapid development of domestic fisheries and aquaculture, the scale of fish pond breeding is expanding arbitrarily, private enclosure of ponds, aquaculture wastewater is discharged without treatment, and the awareness of harmless treatment of sick and dead animals is becoming increasingly serious, and the problem of deteriorating ecological environment is becoming increasingly obvious. [0003] In the ...
