Aquiculturing system process for works with circulating water

Abstract

An industrinized aquatic product culturing technology with closed-loop circulated water system includes such steps as pumping the culture water from culture pool into drum-type solid-liquid separator, removing suspended big particles, making the water flow through a purifying channel to remove suspended small particles and part of NH4-N and NO2-N, collecting the water in a pool, pumping the water into an aerating bio-filter and floating ball type bio-filter, removing the most of NH4-N, NO2-N and COD, by-passing through foam separating-ozone disinfecting unit for removing COD and suspended fine particles while disinfecting and aerating, regulating pH value and water temp, ultraviolet disinfecting, and returning the water back into culture pool.

Description

Technical field: [0001] The present invention relates to industrial aquaculture systems. Background technique [0002] The healthy growth of farmed fish requires a good growth environment. Good water quality is the foundation of aquaculture. Deterioration of water quality will reduce fish production, increase the incidence of disease, and even cause fish death. Therefore, industrial aquaculture with circulating water should be equipped with a safe, efficient and energy-saving water treatment system that is suitable for the water quality requirements of farmed fish. Water-saving, land-saving, unaffected by the environment and climate, continuous production throughout the year, high-yield, high-quality, high-efficiency and non-polluting circulating water industrial farming is a new way to replace resources with technology. [0003] In recent years, many countries have restricted the discharge of aquaculture wastewater containing high concentrations of nitrate from the perspe...

Problems solved by technology

In recent years, although some domestic universities, research institutes and related enterprises have attached great importance to the development of "energy-saving, high-efficiency, safe" aquaculture water treatment new technology, new technology and supporting equipment research suitable for China's national conditions, however, the current domestic circulating water industrialized aquaculture The industry still faces the arduous task of further improving the technical level, increasing the load capacity of fish farming per unit of water body, improving economic benefits, reducing energy consumption, reducing equipment costs and operating costs, and forming the production capacity of facility fishery series equipment
