High-density fish-and-vegetable symbiosis system

Abstract

The invention relates to a high-density fish-and-vegetable symbiosis system which comprises a sewage tank, a support, a drainage main pipe, a fish tank, a cultivation tank, a sewage pump, a circulation pipeline, a water distributor, a cultivation tank water inlet pipe, a sewage pipe water outlet pipe, a clear water drainage pipe, a water distributor water inlet pipe, a central outer pipe and a central inner pipe. The fish tank is composed of an upper cylinder and a lower inverted cone. The center of the bottom of the inverted cone is provided with a groove, the central outer pipe is mounted inthe groove, the central inner pipe is mounted in the central outer pipe and passes through the bottom of the fish tank and is connected with the drainage main pipe at the bottom of the fish tank, thedrainage main pipe is connected with a sewage drain pipe and a clear water drain pipe respectively through a three-way valve, the sewage drain pipe is disposed above the sewage tank, the pipe wall ofthe central outer pipe is provided with a plurality of holes, the holes are covered with a grid, and the height of the central inner pipe is lower than that of the central outer pipe. The system is simple, convenient to operate and low in running and maintenance cost, the quality of treated water is good, the breeding density is large, and the planting yield is high.

Description

Technical field [0001] The invention relates to the field of fish and vegetable symbiosis, in particular to a high-density fish and vegetable symbiosis system. Background technique [0002] The fish-vegetable symbiosis system is through scientific ecological design, ingeniously achieving a harmonious ecological balance between animals, plants, and microorganisms, so as to realize fish farming without changing the water without water quality concerns, and growing vegetables without fertilization is normal The ecological symbiosis effect of growth. The fish-vegetable symbiosis system is natural and organic, water-saving, low-emission, and labor-saving. It is a sustainable and cyclic zero-emission low-carbon production model, and it is the most effective way to effectively solve the agricultural ecological crisis. [0003] The invention patent with the application number 221510089053.X discloses a high-density fish-vegetable symbiosis system, including a fish tank, a hydroponic veget...

[0003] The invention patent with the application number 221510089053.X discloses a high-density fish and vegetable symbiosis system, including a planting system and a reservoir composed of fish tanks, hydroponic vegetable cultivation tanks and river stone cultivation beds. The system can realize high-density fish cultivation , with good energy-saving effect and high-quality water treatment, but it has many devices and a large floor area, which limits the popularization and use of the system

The invention patent with the application number 221410161221.X discloses a fish and vegetable symbiosis integrated system, including a culture system, a layered planting system, a raw material adding mechanism and an algae cultivation and processing adding device. The system uses an automatic control system to monitor and control water quality. The deployment involves many regulating valves and testing instruments, the structure is complicated, the control is complicated, and accurate adjustment cannot be achieved; the breeding system increases equipment investment through independent purification equipment, the structure is more complicated, and the cost is higher, which also affects the production to a certain extent. The popularity of the system
