Fish and vegetable co-existing system and use and control method thereof

Abstract

The invention discloses a fish and vegetable co-existing system which comprises a circulating water culture system, a biofilter, a water culture system, a water pump, a gas pump, a transmission pipeline and an electric control box. The circulating water culture system comprises a fish pond device and a whirlpool separator; the biofilter comprises an anaerobic mineralization pond, an aerobic mineralization pond and a moving bio-membrane reactor; the water culture system comprises a second low-land pond, a dry-wet medium bed, a first low-land pond and a plurality of deepwater floating raft culture beds; the fish pond device, the biofilter, the second low-land pond, the dry-wet medium bed, the first low-land pond and the deepwater floating raft culture beds are sequentially communicated; a water source of the first low-land pond is pumped out to enter the fish pond device to form a circulating system. The invention also discloses a use and control method of the system, so that two culture modes are mutually coordinated to operate in the same system, thereby reaching ecological balance and generating high economic and social benefits.

Description

technical field [0001] The invention relates to the technology in the field of aquaculture and vegetable planting systems, in particular to a fish-vegetable symbiosis system and a use control method thereof. Background technique [0002] The aquaponics system is a combination of two effective hydroponics technologies: the recirculating aquaculture system (RAS for short, which uses a circulating water system for fish farming) and the hydroponics system (crop cultivation without soil). The principle of the fish and vegetable symbiosis system is very simple. It mainly uses the excrement produced by fish as plant nutrients, and the plants absorb nutrients from the water, so as to achieve the purpose of purifying the water source. Wastewater from aquaculture is converted through hydroponic beds rather than being discharged into the environment, while also providing a sustainable, cost-effective, and chemical-free source of nutrients for plant growth. This aquaponics model elimin...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing fish and vegetable symbiosis system is partly an open-loop mode, that is, the fish pond and the hydroponic pond are connected through water pipes, and the water discharged from the fish pond is used as one-time irrigation water to directly supply the hydroponic pond without returning backflow. This model cannot maximize the utilization of resources; some closed-loop aquaponics systems cannot control the ecological balance of the system well, and are still in the experimental stage
