Problems solved by technology

[0002] At present, the traditional equipment-based industrial circulating water fish farming system is used at home and abroad, which has large investment, expensive equipment, high energy consumption in operation, complex operation and management, low economic and ecological benefits, and difficult to popularize and apply.
The patent 200610018309.9 "Ecological and energy-saving factory fish farming horizontal double circulation water treatment facility" invented by me, although the complete set of special equipment in the traditional fish farming factory is omitted, investment and energy consumption are reduced, but there are still large-scale production of fish ponds and water treatment The front and rear of the facilities are separated, the water inlet and outlet ditches occupy a large area, and the utilization rate is not high
However, in my 200810008753.1 patent "A System for Ecological Treatment and Recycling of Industrialized Fish Farming Wastewater", there are many problems in the use of power equipment, high energy consumption, and hidden dangers in the intake and drainage pipes and ditches.

Embodiment 1

[0024] 1. Factory buildings: Plastic greenhouses or brick-concrete structures can be used. The roof is divided into two parts: the light-transmitting area (above the water treatment pool) and the shading area (above the fish pond 1). 22 are built on the fish pond 1 as a shading area.

[0025] 2. Fish pond: its depth is 2m, and it is connected with the primary sedimentation tank 4 by the drainage hole 2 on the bottom wall of the fish pond. Drain into the water hole 13.

[0026] 3. Multi-functional water treatment pool: long strip shape, composed of primary sedimentation tank 4, secondary foam separation tank 5 and water collection tank 11. The residue and dirt deposited in the bottom of the primary sedimentation tank 4 are directly discharged into the biogas digester 18 . The primary treated pool water overflows into the secondary foam separation tank 5. The foam water entrained on the surface of the fish pond 1 flows into the secondary foam separation tank 5 through the wat...

[0032] According to the design requirements of the present invention, fish culture facility is built, and commercial sturgeon culture test has been carried out, specifically as follows:

[0033] 1. Facilities construction and equipment and equipment installation

[0034] 1.1 Fish pond 1: It is octagonal, with a length and width of 11 meters, a depth of 2 meters, and an area of ​​120 meters 2 , volume 240m 3 , consists of two equivalent fish ponds and a water treatment pond.

[0035]1.2 Multifunctional water treatment pool: it is long and divided into three small pools, the primary sedimentation tank is 2×2×3m with an area of ​​4m 2 , volume 12m 3 ;Secondary foam separation pool 3.5×2×3m, area 7m 2 , volume 21m 3 ;Collecting pool 5.5×2×3m, area 11m 2 , volume 33m 3 .

[0036] 1.3 Constructed wetland biofilter 7: square, 11m in length and width, 3m in depth, and 121m in area 2 , volume 363m 3 . Cement partitions are installed deep in the pool, and filter materials suc...

Abstract

The invention discloses an ecological fish farming installation for farming fishes with purified recirculated water, belonging to fishery industry installations. A fish pond and an ecological water purification system, consisting of a single stage settling tank, a second stage foam separation tank, an artificial wetland biological filter, a water collecting tank, an aerator and sterilization equipment, constitute an independent production unit. The installation adopts a process with no water inlet / outlet pipes and ditches, optimizes water body flow direction in the fish pond, increase the retention time of recirculated water, and improves water treatment efficiency. The whole set of installation only uses one air pump as the power for water recirculation. The independent production unit has a yard shape, and multiple sets of the independent production units can be connected in series for industrial application. By using the installation, the fish rod has low water level and large flow rate, and can realize rapid aeration, oxygenation, protein separation, sterilization, disinfection, and full ecological cyclic utilization. The installation has the advantages of simple equipment, reasonable structure, low investment, safe operation, convenient management and maintenance, low water and energy consumption, high efficiency, environmental friendliness, and the like; and can realize resource utilization of fish farming wastewater and residues and achieve zero discharge.
