Fish and vegetable co-existing water circulation system

Abstract

The invention provide a fish and vegetable co-existing water circulation system, comprising a fish and vegetable co-existing device, a nitration device, a leaf vegetable breeding device, and a water circulating supply device. In the fish and vegetable co-existing device, at least a fish is cultured in cultivated water, and the cultivated water is transmitted to the nitration device. The nitration device performs nitrification processing on the cultivated water of the fish and vegetable co-existing device, and transmits the cultivated water which goes through the nitrification processing to the leaf vegetable breeding device. The leaf vegetable breeding device uses cultivated water to breed at least a leaf vegetable. The water circulating supply device recycles the cultivated water in the leaf vegetable breeding device, and supplies the recycled cultivated water to the fish and vegetable co-existing device. Thus, the cultivated water continuously recycles among the fish and vegetable co-existing device, the nitration device, the leaf vegetable breeding device, and the water circulating supply device. The system drains the cultivated water without toxic substances, thereby effectively reducing environmental pollution, and recycling water resources, and preventing waste of water resources.

Description

technical field [0001] The invention relates to a culture system, in particular to a water circulation system for fish and vegetable symbiosis. Background technique [0002] In addition to traditional agriculture and fishery, in order to facilitate the acquisition of agricultural and fishery products, many cities have begun to construct land and systems for urban agriculture and fish farming. In addition to obtaining people's livelihood food materials from fishery production areas, they can also obtain a considerable amount of materials from the aforementioned urban agriculture and fishery systems, so as to reduce production due to abnormal weather in traditional agriculture and fishery production areas, or damage crops due to natural disasters, or encounter international import and export volumes. In the event of a shock, it can provide relatively economical and convenient material support in the city, avoiding a major impact on the people's livelihood and economy. Therefor...

[0004] However, although this kind of conventional urban farming and fish farming system has been constructed with a considerable scale of planting and breeding methods, the customary urban farming and fish farming systems are all set up separately. Traditional agricultural cultivation requires long-term water supply, Ferti
