FIELD: chemistry.
SUBSTANCE: invention relates to biological treatment of waste water. Active sludge and waste water are fed into aerotanks through conduits uniformly and in a dispersed manner, where the conduits lie perpendicular the longer side of the aerotank and are fitted with side drains. The distance between the side drains is not less than 50 mm.
EFFECT: invention increases treatment efficiency by achieving uniform contact between flocci of active sludge and chemically contaminated waste water.
