METHOD FOR INTEGRATED PURIFICATION OF COMPLEX MULTICOMPONENT WASTE WATER Russian patent published in 2021 - IPC C02F3/08 C02F3/14 C02F3/32 C02F3/34 C02F11/02 

FIELD: waste water treatment.

SUBSTANCE: invention relates to the field of waste water purification and can be used for purification of waste water of industrial enterprises, filtration water of SDW disposal sites and landfills from heavy metals, petroleum products, organic substances. The method for integrated purification of complex multicomponent waste water includes supplying waste water to a spatially divided cascade filter composed of no less than three biomodules. The purified water flows from the biomodule with an odd number to the biomodule with an even number in the lower part of the biomodules, and from the biomodule with an even number to the biomodule with an odd number in the upper part of the biomodules. The modules constitutes shallow pools, placed in the first whereof are loads with immobilised bacterial biocoenosis of microorganisms - destructors of organic pollutants, wherein bacterial strains of the genera Bacillus and Micrococcus are used as said microorganisms, placed in the second one are loads with immobilised associations of microalgae of the genera Chlorella, Scenedesmus and cyanobacteria of the genus Phormidium, placed in the third one is loose floating higher aquatic vegetation, wherein hornwort (Ceratophyllum demersum L) and Canadian waterweed (Elodea canadensis) are used as said vegetation. The waste water is aerated naturally due to the large area of the water surface of the pools of the biomodules.

EFFECT: claimed method provides an increase in the efficiency of waste water purification from high concentrations of contaminants toxic to the biocoenosis.
