High-efficiency low-carbon circulating rice and fish culture system and culture method

Abstract

The invention discloses an efficient low-carbon circulating rice and fish culture system and method. The system comprises a culture pond, a dirt collection cone, a detection air guide rod, a negative pressure separation box, a biochemical disinfection carbon sequestration pond, a rice field biochemical purification area, a backwater regulating culture biochemical pond and a monitoring control box. A sewage collection cone is fixedly arranged in the culture pond, an air guide pipe and a detection rod are inserted in the cone top, a first sewage (slag) discharge pipe is arranged at the cone bottom, a disinfection pipe is arranged in the cone, and a second sewage (tail water) discharge pipe is arranged at the pond bottom. By applying physics and microbiology methods, waste discharged by facility culture is separated, degraded and biochemically converted into rich nutrition required by rice growth, culture discharge and rice field consumption are coordinated and balanced by adopting a scientific method, a rice-water-fish ecological link system taking water as a medium is constructed, and the rice yield is improved. And solid-phase, liquid-phase and gas-phase energy substances in the ecological system are captured, converted and utilized in a rice field'container ', a carbon source and a nitrogen source are solidified and neutralized, and zero emission of pollutants is realized.

Description

technical field [0001] The invention relates to the technical field of intelligent agricultural Internet of Things, in particular to a high-efficiency and low-carbon circulating rice-fish breeding system and a breeding method. Background technique [0002] In the facility aquaculture system, the fish farming density is high, the pollutant discharge is large, and the waste in the water body is discharged, including the residual bait caused by feeding the bait, the undigested and absorbed nutrients, the fish metabolic excrement and Microbial residues (bacteria and algae), etc. During the aquaculture process, aquaculture metabolites are discharged into the water, including soluble substances such as ammonia nitrogen, nitrate, nitrite, etc., as well as solid substances such as residual bait, fish manure, suspended solids such as insoluble particles, and gas (soluble substances). ) substances such as CO2, NH4, the accumulation of these substances and microbial residues will have...

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that the rice-fish breeding system in the prior art is relatively simple, the fish breeding cycle is short, the output is low, the facilities are scarce, the production of rice and fish is mutually restricted, and the method and technology are simple; the breeding system cannot quickly and effectively treat waste in the water body. It is difficult to carry out discharge treatment, and the recycling and utilization of waste water and waste residue; the intelligent level of production management is low, and the Internet of Things technology has the problem of block barriers, and a high-efficiency and low-carbon circular rice fish breeding system and breeding method are proposed.
