Aquatic product and vegetable symbiotic system and use method thereof

Abstract

The invention discloses an aquatic product and vegetable symbiotic system and a use method thereof. The symbiotic system comprises a fish culture system, a microbial treatment system, a vegetable pooland a water recovery system which are sequentially connected in a closed mode through pipelines, wherein the fish culture system comprises a plurality of fish tanks; the fish tanks are averagely divided into two rows; the bottoms of the fish tanks communicate through pipelines; the microbial treatment system comprises a microbial reaction tank and a first water storage tank; the bottom surface ofthe first water storage tank is lower than that of the microbial reaction tank; a first water pump is arranged on a pipeline connecting the microbial reaction tank and the fish tank; the microbial reaction tank communicates with the first water storage tank through a pipeline; a second water pump is arranged in the first water storage tank; the first water storage tank is arranged at the front end of the vegetable pool; the water recovery system is arranged at the tail end of the vegetable pool and comprises a second water storage tank; the bottom surface of the second water storage tank is lower than the bottom surface of the vegetable pool; a filter device is movably connected to the upper portion of the second water storage tank; and a third water pump is arranged in the second water storage tank. Water in the system can form circulation, so that water resource waste is reduced, and the water resource utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture and vegetable planting, and in particular relates to an aquatic vegetable symbiosis system and an application method thereof. Background technique [0002] With the improvement of people's living standards, agricultural production has also entered the field of industrialization. While the industrialization of agricultural production has brought large-scale integrated production to people, it has also had a huge impact on people's lives. my country is a big aquaculture country in the world. The output and area of ​​aquaculture rank first in the world. However, the traditional aquaculture method is at the expense of the environment. During the aquaculture process, every kilogram of fish can discharge 1-2g of ammonia nitrogen to the water body every day and consume 5-5% of dissolved oxygen in water. 6g (equivalent to 2 days of natural reoxygenation on 1㎡ of water surface), 1.5m of polluted water ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides an aquatic vegetable symbiosis system and its use method, which can effectively solve the problem that the existing symbiosis system cannot form a cycle of water, resulting in waste of water resources, and the consumption of chemical fertilizers big problem
