FIELD: chemistry.
SUBSTANCE: sanitary-engineering installation for decontamination of transport waste water contains waste water receiver 2, pipeline 3, storage container 4 provided with level regulator 6, system of compressed air feeding, means of waste treatment designed as tube vertically positioned in the centre of additional tank 8 in which the biological charge 11 and small bubbles generating aerator 12 are located. Additional tank 8 is provided with at least two pair of airlift 14, 15, pipeline 25 with valve 24 for decontaminated water release and pipeline 23 with valve 22 for sludge release. Installation provided with interacting control unit 7, compressor 18, switching valve 19, and direction control valve 21 with regulator 20. The installation implies two operation methods providing the down and up bubbles movement in the waste treatment means.
EFFECT: efficiency enhancing of transport waste water treatment, increase of process economy and installation maintainability.
