A kind of track type aquaculture water treatment system and its process method

technical field

The invention relates to a track-type aquaculture water treatment system and a process method thereof, belonging to the technical field of aquaculture equipment.

Background technique

Today, with limited water resources and ever-expanding marine fishing industry, the marine fishing industry will reach or approach saturation one day. Therefore, only by vigorously developing the aquaculture industry can the supply and demand of aquatic products be met in a real sense. In aquaculture, water quality is an aspect that cannot be ignored. The quality of water directly affects the production and development of the breeding objects. Every aquatic animal needs water quality conditions suitable for its survival. If the water quality can meet the requirements, the breeding of animals can be successful. Growth and development, some indicators of water quality are beyond the range of adaptation and tolerance of organisms. If the light ones, the farmed animals cannot grow normally, and if the severe ones may cause a large number of farmed animals to die, bringing immeasurable economic losses to the farmers. According to statistics, 85% of aquatic diseases are caused by water quality problems, so water quality management is very important to the aquaculture industry.

In recent years, the scale of the aquaculture industry in the Yangtze River Delta region has also continued to grow. While maintaining local dominant species, it has also introduced new and valuable species, such as koi, saury, puffer fish, perch and other species. However, the water bodies in the Yangtze River Estuary have been polluted to varying degrees, and special aquaculture species are more sensitive to water pollution. Therefore, in order to raise special aquaculture species more rationally and with high quality, many special aquaculture farms are transforming to industrialized recirculating aquaculture. .

At present, the price, energy consumption and operating cost of most domestic water treatment facilities and equipment remain high. In order to ensure the sustainable development of the aquaculture industry, it is necessary to reduce the water consumption in the aquaculture process to a large extent on the premise of meeting the water quality requirements. Energy consumption, cost, space. Therefore, how to change the existing aquaculture system model, reduce the energy consumption of aquaculture, improve the quality of water treatment, and optimize the water treatment system will have a significant impact on the development of aquaculture in the Yangtze River Delta region of my country.
