FIELD: chemistry.

SUBSTANCE: invention relates to systems of sewage purification. System of sewage purification contains grease-trap, pneumatic flotation machine, electrochemical purification module, sorption filter and bio-reactor. Grease-trap contains ferroconcrete body, made in form of parallelepiped, which has inclined bottom and vertical walls, above which mounted is demountable deck, which is demounted when mass which came to the surface is removed. Under upper deck at distance not less than 30 cm mounded is demountable lower deck for carrying out preventive works or solving emergency situation in case of volley emissions. Box for regeneration of grease-trap by hot water or steam or mechanical means adjoins one of vertical walls, and opposite box on vertical wall placed is pipeline for sewage water supply, and intake opening for discharge of sewage is placed in lower part of body near emergency valve for discharge, and vibrators, whose outlets are connected with control unit, are mounted on one of vertical walls and body bottom.

EFFECT: increase of work reliability and improvement of exploitation conditions in emergency situations.
