Embodiment 1
[0020] A water purification and recycling system for fish breeding ponds, including ecological ditches, secondary purification ponds, tertiary purification ponds and aquaculture ponds:
[0021] Ecological ditch: with the river as the main body, a total of 12 hectares of the river, on both sides of the river and in the middle of the river water hyacinth, water peanuts and other floating aquatic plants are planted in a total area of 4 hectares, and silver carp, silver carp, mussels, and freshwater shrimp are stocked at the same time. A total of 200 kg, forming a natural water purification system. The water that has passed through the primary purification flows into the secondary purification pond through the overflow dam.
[0022] Secondary purification pond: It is the main body of the entire circulating water purification, and it is a 26-hectare earthen pond, where the breeding water is mainly purified. About 9 hectares of aquatic plants such as cabbage, water chestnut, wate...
Embodiment 2
[0027] A water purification and recycling system for fish breeding ponds, including ecological ditches, secondary purification ponds, tertiary purification ponds and aquaculture ponds:
[0028] Ecological ditches: with the influent channel as the main body, a total of 5 hectares of the channel, the total area of 20 mu of floating aquatic plants such as cabbage and water chestnut is planted on both sides of the channel and in the middle, and silver carp, silver carp, river mussel, freshwater shrimp, 80 kg of crabs, soft-shelled turtles, and crayfish form a natural water purification system. The water that has passed through the primary purification flows into the secondary purification pond through the overflow dam.
[0029] Secondary purification pond: It is the main body of the entire circulating water purification, and it is a 17-hectare earthen pond, where the aquaculture water is mainly purified and put into a 1-hectare composite biological floating bed. About 6 hectare...

Abstract
The invention discloses a system for purifying and circularly utilizing water in a fish aquaculture pond, and the system comprises an ecological channel, a secondary purification tank, a tertiary purification pond and a culture pond, and the ecological channel, the secondary purification tank and the tertiary purification pond are respectively provided with aquatic plants and aquatic animals having a purification effect. The invention also discloses a method for purifying and circularly utilizing the water in the fish aquaculture pond, and the method is characterized in that by utilizing the system, the water is sequentially purified in three levels and then enters the aquaculture pond through the power, and waste water in the aquaculture pond is re-discharged into the ecological channel to form the circulation of the entire culture process water. Through the three-level purification, the internal circular purification of the aquaculture water can be realized, the dependence on external water can be greatly alleviated, no pollutant is discharged, environmental friendliness can be realized, the health development of the aquaculture can be realized, a majority of the aquatic plants and the aquatic animals are cash crops, and the culture benefit can be effectively increased; and moreover, simplicity in operation is realized, the cost is low, and popularization in different types of ponds can be realized.
Description
technical field [0001] The invention relates to a system and method for purifying and recycling fish breeding pond water, belonging to the technical field of aquaculture. Background technique [0002] Pond farming is the main farming mode of freshwater fish farming in my country. In the traditional pond farming mode, the water for aquaculture is usually pumped from the external water body to the aquaculture pond for direct use after simple filtration, and then directly discharged into the external water body after a cycle of aquaculture. This farming mode is not only highly dependent on the external water body, but also easily brings pathogens in the external water body to the farming pond, causing fish diseases. In addition, the aquaculture water with feed residues after aquaculture is directly discharged into the external water body, causing aquaculture pollution. With the advancement of urbanization, there are more and more harmful substances in the external water body....
