Freshwater fish and vegetable symbiotic closed circulation system

Abstract

The invention relates to a freshwater fish and vegetable symbiotic closed circulation system. The freshwater fish and vegetable symbiotic closed circulation system comprises a culture subsystem, a filtration and precipitation subsystem, a biochemical treatment subsystem, a vegetable soilless culture subsystem, a water quality stabilization subsystem, an intelligent monitoring and automatic adjusting subsystem and a waste animal and plant treatment subsystem, wherein the filtration and precipitation subsystem comprises a microfilter and a precipitation pond, the microfilter is used for filtering impurities in the culture pond, and the impurities are precipitated at the bottom of the precipitation pond; the biochemical treatment subsystem comprises a biochemical treatment pond, and the vegetable soilless culture subsystem comprises a water layer, a planting layer, a filler layer and a hollow layer which are sequentially arranged from top to bottom; the water quality stabilization subsystem comprises a light supplementing lamp and a plurality of aeration pipes; the intelligent monitoring and automatic adjusting subsystem receives the collected information of each subsystem and correspondingly adjusts the collected information; and the waste animal and plant treatment subsystem is used for feeding insects. According to the freshwater fish and vegetable symbiotic closed circulation system, fish and vegetable symbiotic modular combination is utilized, the proportion is determined by adopting a scientific calculation method, and an intelligent closed type fish and vegetable symbiotic circulating water planting and breeding comprehensive technology system with a complete subsystem is established by utilizing application of various fusion subjects; and all-year-round planting and breeding production can be carried out, organic waste in the planting and breeding process is reduced, and environment-friendly production is achieved.

Description

technical field [0001] The invention belongs to the technical field of breeding and planting, and in particular relates to a freshwater fish and vegetable symbiotic closed circulation system. Background technique [0002] Aquaponics is a new type of compound farming system, which combines two completely different farming techniques, aquaculture (Aquaculture) and hydroponics (Hydroponics), into a planting subsystem. In traditional aquaculture, with the accumulation of fish excrement, the ammonia nitrogen in the water body increases, and the toxicity gradually increases. In the aquaponics subsystem, the aquaculture water is transported to the hydroponic cultivation subsystem, where the bacteria decompose the ammonia nitrogen in the water into nitrite, which is then decomposed into nitrate by nitrifying bacteria, which can be directly used by plants as nutrients Absorb and utilize. Aquaponics allows animals, plants, and microorganisms to achieve a harmonious ecological balanc...
