Pond ecological breeding system capable of being freely combined

Abstract

The invention discloses a pond ecological breeding system capable of being freely combined. The system comprises a pond, a breeding box and a modular tail water treatment system; the pond is a carrierof the breeding box, the breeding box comprises a breeding box body and a breeding box support, and the breeding box is of a detachable splicing structure; and the modular tail water treatment systemcomprises a tail water precipitation module, a biological brush module, a planting purification module and an artificial wetland module. The system is more optimized in the aspects of overall layout,space utilization, construction cost, construction difficulty, wastewater utilization, energy conservation and emission reduction, culture benefits and the like, and is a culture system widely suitable for pond culture. The system also has ecologicalization, diversification and general adaptability; and compared with previous pond culture, the system is low in construction cost, can flexibly select materials according to actual requirements of fishermen, can realize high-density intensive, ecological (zero-emission), quality-based, automatic and diversified modern culture at the same time, and is a new choice for optimization and upgrading of pond culture at the present stage and in the future.

Description

technical field [0001] The invention relates to the technical field of ecological breeding, in particular to a freely combinable pond ecological breeding system. Background technique [0002] Pond aquaculture is the main method of freshwater aquaculture in my country. With the continuous development of our society, people pay more and more attention to the quality of aquatic products and the breeding environment, and ecological aquaculture is the general trend. High-density intensive aquaculture methods such as cage aquaculture are limited, and the cost and risk of industrial recirculating aquaculture and terrestrial intensive aquaculture are relatively high. However, pond aquaculture is still the main body of freshwater aquaculture. And the specifications are different, the majority of farmers urgently need a culture system that can generally adapt to the pond to come out and promote. [0003] At present, most pond aquaculture is still relatively traditional, and many fish...

AI Technical Summary

Problems solved by technology

Although the pond engineering captive breeding system has obvious water purification effect, there are still many shortcomings: (1) The breeding tank of the pond engineering captive breeding system is circular, with a conical bottom and a diameter of 4m. It is composed of two symmetrical parts. The cost is high, the assembly is difficult, and the construction intensity is high; (2) the water inlet of the sewage collection tower is 3m above the ground, the sewage outlet at the bottom of the breeding tank is 3m deep, and the water level difference reaches 6m. The power of the supporting sewage pump is 4kw, and the lift is 20m. And every four breeding tanks need to be matched with a set of sewage collection and discharge facilities, which has high construction costs and energy consumption; (3) The sludge deposited at the bottom of the sewage collection tower needs to be cleaned manually, which is a waste of manpower and cannot be directly and fully utilized; (4) ) Once the system is built, it is difficult to change, each circle cannot be connected in series, and flexible modification cannot be realized, and the breeding space is limited to a single circle; (5) Most areas of the pond ridge are idle, resulting in waste of resources and space, The multiple benefits of the combination of planting and breeding have not been realized; (6) Overall, the construction cost of this captive breeding system is relatively high, and the economic strength of the vast number of individual farmers has not been fully considered, and it is still difficult to promote

The floating circular trough running water aquaculture system is built with flexible materials, and there are many shortcomings, including limited aquaculture space, easy growth of moss to block the drainage window and the mesh of the sewage fence, poor water exchange effect, high energy consumption for artificial aeration, and stable Poor resistance and difficult to use for a long time
