Problems solved by technology

[0004] At present, the main methods of timely removal of nitrogen and phosphorus in aquaculture ponds include fish and vegetable symbiosis mode, pond circulating water mode, pond runway fish mode, land-based push water container culture mode, etc. Disadvantages such as high energy consumption and high overall cost of breeding have limited large-scale promotion; therefore, it is necessary to explore a new pond structure that is suitable for promotion and can remove nitrogen and phosphorus in aquaculture ponds in time

Embodiment 1

[0041] Embodiment one, refer to the description attached figure 1 - 7. A funnel-shaped pond ecological circulation culture system, the culture system includes a funnel-shaped fish pond set in the soil foundation, a fish excrement separation device arranged on one side of the funnel-shaped fish pond, a greenhouse ecological ditch, a lotus root pond, rice fields, ecological The purification pool, the aquatic plant absorption pool, and the funnel-shaped fish pond are provided with heat preservation sheds; the tapered outlet of the funnel-shaped fish pond is provided with two layers of anti-escape nets to prevent fish from escaping from the sewage outlet.

[0042] There is a shaft between the fish dung separation device and the funnel-shaped fish pond. The fish dung separation device includes a cylindrical separation tank with a conical bottom, an isolation sleeve vertically placed in the middle of the cylindrical separation tank, and a The mixing nozzle inside, the middle of the...

Embodiment 2

[0048] Embodiment two, refer to the appended figure 1 - 7, the method for culturing according to a kind of funnel-shaped pond ecological circulation culture system described in embodiment one, comprises the following steps:

[0049] The first step: Start the circulating pump to continuously add water to the funnel-shaped fish pond, so that a water pressure difference is formed between the mixing nozzle of the fish manure separation device and the water surface between the funnel-shaped fish pond;

[0050] Step 2: The fish feces and residual bait produced by the fish continuously slide down the side wall of the funnel-shaped fish pond to the center of the bottom of the pond. The water pressure difference will cause the downstream water to form a natural swirl and be discharged from the sewage pipe A. Bring the falling fish manure into the sewage pipe, and flow from the mixing nozzle into the isolation sleeve of the fish manure separation device through the shaft; Turning cloc...

Embodiment 3

[0057] Example 3, sewage discharge test of cyclone booster device

[0058] See attached figure 2 , 7 , the swirl booster device includes a deceleration motor, a suspension ball, and a swirl paddle. The lower part of the deceleration motor is evenly distributed with 3 suspension balls through a horizontal support rod. The output shaft of the deceleration motor is fixedly connected with the same axis, and the deceleration motor is connected with a frequency conversion switch to control the speed. The speed of the swirl paddle is controlled by the frequency conversion switch, thereby controlling the speed of the water flow to form a swirl, and controlling the discharge speed of fish dung; the swirl paddle The blades on the top are set as two straight blades or three curved blades that are generally circular, and the straight blades and curved blades are evenly distributed on the central axis of the propeller.

[0059] The shape and number of blades on the swirl propeller of th...

Abstract

The invention relates to a funnel-shaped pond ecological circulating culture system. The funnel-shaped pond ecological circulating culture system is characterized in that a first circulating system is formed by a funnel-shaped fish pond, a fish manure separation device, an aquatic plant absorption pond and an ecological purification pond, and the circulating system is used for carrying out multi-stage purification on clear water obtained after fish manure separation and realizing cyclic utilization; a rotational flow power assisting device in the funnel-shaped fish pond accelerates the gathering speed of manure and residual feed from the conical side face of the fish pond to a sewage draining outlet in the center of the bottom; tail water obtained after fish manure separation is subjected to multi-stage utilization and purification through the fish manure separation device, an ecological ditch, a lotus root pond, a rice field and the ecological purification pond, so that resource recycling is achieved; the fish manure collected by a sedimentation pond in the ecological ditch is fermented through a fish manure fermentation channel, so that fertilizer capable of being directly used for commercial crops is formed. According to the funnel-shaped pond ecological circulating culture system, zero emission of culture tail water is realized, the system has the advantages of energy conservation, land conservation, water conservation, high efficiency, high quality, environmental protection and the like, defects of traditional pond fish culture are overcome, and the system is a green and healthy aquatic product culture mode which is worthy of vigorous popularization at present.

Description

technical field [0001] The invention relates to the technical field of fish breeding equipment, in particular to a funnel-shaped pond ecological circulation breeding system and method. Background technique [0002] In intensive ponds, only about 1 / 3 of the nitrogen and phosphorus nutrients input in the form of bait are assimilated and absorbed by aquatic animals, and most of the remaining nutrients remain in the aquaculture water body and bottom mud in the form of residual bait and fish and shrimp excrement. The deterioration of water quality has affected the growth of fish and shrimp, and the discharge of tail water from aquaculture has also aggravated the pollution of the surrounding water environment. [0003] With the continuous improvement of the degree of intensification, eutrophication of the aquaculture water, the outbreak of blue-green algae, the frequent occurrence of fish diseases, and the large amount of drugs used by farmers have caused hidden dangers to the qua...
