Fish and vegetable symbiotic system and application thereof

Abstract

The invention discloses a fish and vegetable symbiotic system and application thereof. The fish and vegetable symbiotic system includes a water inlet, a water storage tank, at least one filter tank, avegetable planting pipeline, a drainage port, a waste liquid treating tank and a fish framing water tank which are all connected in sequence; the fish framing water tank is lower than the position ofthe waste liquid treating tank. By adopting the fish and vegetable symbiotic system, firstly, vegetables are planted in the vegetable planting pipeline, and fish are farmed in the fish framing watertank; then, water in the fish framing water tank is transported into the water storage tank, and after being filtered by the filter tanks, the water is transported to the vegetable planting pipeline;finally, the water is transported to the waste liquid treating tank, and after being treated, the water is transported back to the fish framing water tank. In this way, water current circulation is formed, the eutrophic water can be converted into water suitable for survival of aquatic organisms, meanwhile, nutrient substances in the eutrophic water are used as plant fertilizer, therefore, waste of water resources is reduced, and the cost can be reduced.

Description

Technical field [0001] The invention relates to the technical field of ecological planting and breeding methods, in particular to an aquaponics symbiosis system and its application. Background technique [0002] At present, in the field of aquaculture technology, in the breeding process of fish ponds, aquatic organisms will discharge excrement after eating feed, and the excrement contains ammonia, which makes the water of the fish pond also contain ammonia, which improves the eutrophication of the water. The eutrophication of water is not conducive to the growth of aquatic organisms, and even affects the normal growth and development of aquatic organisms. Therefore, in order to prevent the eutrophication of water from causing harm to aquatic organisms, farmers need to replace part of the aquatic organisms regularly. Water, so as to ensure that the quality of the aquaculture water meets the growth needs of aquatic organisms. [0003] However, if the aquaculture water is directly di...

Problems solved by technology

[0003] However, if the aquaculture water is directly discharged, on the one hand, it will cause a waste of water resources and increase the cost of aquaculture. At the same time, the direct discharge of the aquaculture water rich in ammonia will also cause certain pollution.
