Guangzhou zhonghang Factory Circulation Farming System
System process: The typical process and equipment of factory circulating water breeding system is based on physical filtration combined with biological filtration as the main body, deep purification of breeding water, and integrated with automatic water quality monitoring system, real-time monitoring and regulation of the quality of the breeding water and can be traced. The system has the advantages of perfect process technology, good water treatment effect, stable water quality condition, comfortable production operation, easy equipment maintenance, low operation cost and system investment.
This is a set of concise and effective process technology route: the water from the fish pond flows freely into the microfilter pool to remove the residual bait and fish feces and other particles with a diameter greater than 60 microns of solid suspended matter, which is elevated by the pump into the biofilter, which intercepts tiny particles of suspended matter on the one hand, and degrades ammonia and nitrogen in the water on the other hand, and the purified water flows freely back to the fish pond. Parallel bypass is activated when the water body needs sterilization, temperature regulation or the water body has a tendency of turbidity, to sterilize and regulate the temperature of the water body. It controls the living environment of aquaculture organisms and carries out scientific management, so as to get rid of the limitation of natural resource conditions such as land and water, and is a kind of high-density, high-yield, high-input, high-efficiency and high-yield aquaculture method.
Characteristics of factory circulating water aquaculture The essence of factory circulating water aquaculture is the industrialization of aquaculture production, the production process is controllable and can be farmed across seasons, and the products can be marketed in a planned and balanced manner like industrial products.
Its characteristics:
Factory circulating water aquaculture system is to achieve controllable, high-density, low-cost, environmental protection, healthy aquatic products and many other conditions, the running cost is very low, the equipment investment cost is a little larger acceptable, because it is a one-time investment, energy saving, low cost is the key. So it must be automated to reduce labor and lower the bottom error. Guangzhou ZhongHang factory circulating water aquaculture system to achieve one-key control; automatic start, automatic stop, automatic water replenishment, automatic sewage, automatic oxygenation, automatic control of water temperature, real-time online monitoring of water quality (support for cell phone to view), water quality abnormalities in the microblogging alarm to notify the relevant person in charge, but also an automatic feeding machine can be optional. One of the control of dissolved oxygen is very important, especially for high-density farming users, water quality a day without treatment can barely cope, but an hour without oxygen may cause irreparable losses to the user, automatic oxygenation is a very important one, it must be automatic oxygenation, in order to minimize the error to a large extent.
