1. An industrial fish breeding complex, comprising:
a group of fish breeding pools and
a water regeneration system, located aside the pools and comprising
a mud settler-denitrificator,
a device for water lifting and aeration,
a multisectional modular biological filter, comprising
biological filter modules, wherein each module comprising a biological reactor, made as a reservoir with four vertical walls and a rectangular horizontal cross-section, a reservoir bottom is sloped in a direction of a water movement and together with a plane of a water surface forms a diffuser which provides for favorable conditions for circulation of water and a filler in the biological reactor, in a lower part of a connection of the reservoir bottom and the vertical wall there is a channel for a sludge accumulation and discharge, which in an upper part is limited by a separation grid which prevents the filler of a biological filter from going into the channel, under the grid in the channel an aerator is placed, providing for accelerating a circulating water and filler flow with an ascending air stream from the aerator, as well as oxygenating the water;
a degassing unit and
a disinfection unit,
said group of pools being connected by a water supply distributing channel,
a wastewater collecting channel,
a common system of collecting and discharge of insoluble residues, and
a mechanical filter of insoluble residues.
