High-density aquiculture system and aquatic product breeding and fruit/vegetable planting system

Abstract

The invention relates to a high-density aquiculture system, which comprises a main aquiculture pond, a sewage collection and discharge device, a water purifier, a microbial purification waterbed and a circulating water pump, wherein an excrement collection port is arranged at the bottom of the main aquiculture pond and is connected with a circulating water pipe; the sewage collection and discharge device is connected with the excrement collection port through the circulating water pipe and an excrement discharge outlet is arranged at the bottom of the sewage collection and discharge device; the water purifier is provided with an organic matter water solution outlet and is connected with the sewage collection and discharge device; ammonia nitrogen digestion aquatic plants are planted in the microbial purification waterbed, the microbial purification waterbed is provided with a water inlet and a water outlet, the water inlet is connected with the water purifier and the water outlet is connected with the main aquiculture pond; and the circulating water pump is arranged in the microbial purification waterbed at the end adjacent to the water outlet. The high-density aquiculture system has the advantages that an optimum growth environment of high-density fish is guaranteed; and at the same time, high-effect and high-quality organic fertilizers can be provided, so as to meet the demands for various nutrient elements for daily growth of fruits/vegetables.

Description

【Technical field】 [0001] The invention relates to a high-density aquaculture system and an aquatic fruit and vegetable breeding system. 【Background technique】 [0002] At present, there are about 300 million mu of freshwater aquaculture area in China. Most of these aquaculture areas are artificially dug fish ponds into the traditional aquaculture mode, making positive contributions to solving the problem of eating fish. However, the traditional fish pond farming technology, which cleans up the sewage discharged from the fish pond to the surrounding area every year, has become a serious source of environmental pollution. Traditional breeding not only occupies a lot of land, but also has low resistance to natural disasters and diseases, and the situation of general-purpose pesticides, antibiotics, and hormone drugs is serious, causing farmers and enterprises to increase the cost of breeding, but the output is low, the quality is low, and the economic benefits are not good. Th...

Problems solved by technology

However, the main factors currently restricting development: 1. Large investment: it is difficult for ordinary enterprises and individuals to bear; 2. The water treatment technology is not up to standard, and the cost of breeding operation is high; 3. There is a lack of high-quality and high-priced breeding varieties; 4. Breeding technology and technology management can't keep up

The above fully demonstrates that the traditional breeding mode occupies a large area, the breeding quality is not high (with drug residues), and the sewage discharge seriously pollutes the surrounding environment
