FIELD: treatment of water.
SUBSTANCE: invention relates to the field of pretreatment of transported waste water. The method for pretreatment of waste water transported in pressurised or non-pressurised modes in pipelines or trays includes supplying reagents to the waste water, wherein oxidising and disinvasive reagents are introduced into the stream of waste water when mixing simultaneously from a single solution container or from two separate solution containers, and hydrogen peroxide and/or sodium hypochlorite are used as oxidisers, providing the redox potential of the mixture with waste water no lower than 0 mV with the time of transportation of waste water to the treatment facilities of at least 1 h and with gas removal no more than 1 hour after the reagents are introduced, wherein the reagents are supplied to any point of the gravity-flowing water discharge network and/or to the receiving tank of the pumping station, and/or to the pressure pipeline.
EFFECT: reduction in the content of hydrogen sulphide, organic substances, and parasitic contamination in the entire volume of transported waste water.
