摘要：
The utility model relates to fish farming and water purification using biological filters and can be used to equip various types of fish breeding systems to purify water from organic pollutants, both as one of the components of the purification system and as the only biofilter. The biofilter for water purification in fish breeding systems contains a cylindrical body with a cone-shaped base and a sludge outlet pipe, a hydraulic elevator located in the center of the body, on the upper part of which there is an annular tray and a grid that holds floating bio-loading granules, and a drainage pipe. Additionally contains an overflow nozzle located above the retaining grid, a main chamber with granules of regenerating disorganized bio-loading with neutral buoyancy, a separation chamber located in the lower part of the housing, the base of which is the bottom of the housing and is an inverted cone with a sludge outlet located on top for periodic discharge of the falling draft. The upper part of the separation chamber is made in the form of a cone, rigidly fastened to its lower part, and has slots located in a circle at a minimum permissible structural distance with respect to the walls of the housing, the upper cone of the separation chamber is the bottom of the main chamber and has a slope of 30 ° to the walls of the housing the upper part of the lid of the separation chamber is rigidly connected to the hydraulic elevator, which extends beyond the housing cover 1/3 of the total length of the hydraulic elevator, in its upper part there is a water supply pipe, diam Tp which is half the diameter of the hydraulic elevator. The total area of the slots in the upper part of the separation chamber is equal to the area of the outlet of the hydraulic elevator. Bio-loading granules occupy 70% of the volume of the main chamber. The inventive biofilter for water purification in fish breeding systems is easy to operate, reliable and ensures proper purification of the resulting water.Пол
