Description

The invention relates to the treatment and purification of natural and waste waters related to installations and apparatus for water purification and can be used in fish farming for the purpose of purifying water used for mass cultivation of aquatic organs under artificial conditions. A known water treatment unit comprising a biofilter body with a bottom and a filtering load placed on a perforated horizontal partition, supply units for the initial liquid and removal of a-liquid, as well as a collection tank. However, the known installation does not provide for the removal of the saturation of the liquid from the purified WATER. oxygenated air and water purification from suspended matter, which are dead pieces of a biological film from denitrifying microflora. The purpose of the invention is to increase the efficiency of use by removing from the water excess nitrogen, which is present in the form of free ammonia, ammonium salts and nitrites, as well as organic substances with a one-time process ensuring an optimal gas regime of purified water. This goal is achieved in that the installation is supplied with rows mounted on a perforated partition along the rectangular section section in which a filtering load is placed, perforated distribution pipes located under the load and connected to the source fluid supply unit, and an additional filter placed between biofilter housing and tank assembly. Fig. 1 is a diagram of a pre-installed water purification plant;
