What is required for the installation of indoor circulating aquaculture system equipment?

This factoryThe equipment of the circulating water system includes: fully automatic microfiltration machine, protein separator, ozone machine, residual ozone remover, biological filter, deoxygenation and sterilization integrated processor, oxygenator, thermostatic system, fish pond and other aquatic equipment. The source of the material is Air China Environmental Protection.

The configuration of the circulating aquaculture system includes: protein separator, ozone all-in-one machine, residual ozone remover, degassing and sterilization integrated processor, floating bed biological filter, fully automatic drum microfilter, and 6 conical farming fish ponds.

Circulating aquaculture equipment includes: fish pond: PP fish pond. Now many people are using PP fish pond, which is mainly convenient to move, simple to maintain, and durable.

Generally speaking, the price of the circulating water system is between 1,000 yuan and 5,000 yuan, and the price of auxiliary equipment is between 500 yuan and 2,000 yuan.These prices are for reference only, and the specific prices need to be determined according to the local market conditions. In the process of recycling water for home decoration, some expenses also need to be considered.

Save time and effort, no need to change the water frequently; 2) It can automatically maintain the cleanliness of the water body and reduce the damage to organisms; 3) It is conducive to maintaining the stability of the water body and improving the success rate of breeding.

The significance of intelligent fish pond breeding system design

The commissioning of intelligent fish pond management system can not only effectively improve economic efficiency, but also contribute to the increasing improvement of aquaculture production technology and the implementation of standardized farming requirements. Strictly control the use of inputs and the water quality of the pond.

Future Farm: The intelligent agricultural management system supports cultivation, planting, management and harvesting in an all-round way, so that crops can be traced back throughout the whole process.

This not only solves the self-pollution of pond farming, but also turns waste into treasure. At the same time, the whole pond realizes circulating micro-flowing water to raise fish, thus effectively improving the economic, social and ecological benefits of pond farming. At present, pond circulating water breeding technology has been widely promoted and applied in 18 provinces and cities in China.

It can be widely used in large-scale farms, breeding communities, organic fertilizer factories and manure treatment centers, forming a whole industrial chain for the comprehensive utilization of livestock and poultry manure collection, storage, transportation and treatment.

The significance of Sanji Fish Pond The significance of Sanji Fish Pond is to give full play to the symbiotic relationship between material circulation, energy flow transformation and organisms in the ecosystem, promote the mutual circulation of animal and plant resources, which is conducive to maintaining ecological balance. It is a production model with excellent production effect.

Specifically, the following measures are usually adopted for refined fish ponds: Fish pond site selection and design: choose a place with beautiful environment, fresh water quality and convenient transportation to build a fish pond, and design a reasonable fish pond structure and water flow system according to the growth habits and ecological environment requirements of fish.

Which system in the breeding circulation system plays a role in purifying the water body?

1. Establish a nitrifying bacteria system in the fish tank, which can play a good purifying role. Nitrobacteria can take effect immediately after being put into the water. However, at the beginning, due to the relatively small number of nitrifying bacteria in the water, the effect is not obvious, and it may not be observed with the naked eye.

2. Automatic monitoring system of aquaculture water bodies: The most advanced factory-activated water aquaculture system software in countries around the world all adopts the automatic monitoring system of aquaculture water bodies for comprehensive self-start operation, which maximizes the stability of the operation system and reduces manpower costs.

3. The filtered water in the fish farming system also contains bacteria, viruses and other pathogens, so it is necessary to disinfect it.

4. The ecological ditch is an ecological purification system built by using the inlet and drainage channels of the farm. It is composed of a variety of animals and plants, and has the functions of purifying water bodies and production.
