METHOD OF PURIFYING WASTE WATER AND PROCESSING PRECIPITATE INTO ORGANIC FERTILIZERS Russian patent published in 2020 - IPC C02F1/78 C02F9/14 

FIELD: treatment of water, industrial and household waste water.

SUBSTANCE: invention relates to a method of treating waste water and processing the precipitate into organic fertilizer. Method consists in stage-by-stage chemical-physical treatment of incoming waste water with separation of dissolved and suspended components of incoming admixtures with subsequent removal of dry sediment. Wastewater is exposed to ozone and an additional oxidant at all cleaning stages, and only sterile components are obtained. In complex mechanical treatment plant, waste water is passed through three units of pressure electric flotation equipped with electrochemical oxidation units, fine aeration via ceramic membranes, mechanical filtration and foam collection scrapers. In the sediment to be separated, a consortium of soil microorganisms is introduced, which perform microbiological processing of hard-to-access organic and inorganic compounds in a form accessible to plants - biohumus, organic fertilizers.

EFFECT: technical result consists in improvement of quality and efficiency of waste water treatment, as well as processing of wastes into organic fertilizers.
