WASTE WATER PURIFICATION METHOD Russian patent published in 2021 - IPC C02F9/00 C02F9/12 C02F1/463 C02F1/32 C02F1/48 B01D61/14 

FIELD: purification systems.

SUBSTANCE: invention can be used in purification systems in the metallurgical, mining, pulp and paper, food, chemical and agricultural industries for the purification of industrial and sewage effluents, drainage and waste waters and leachates of landfills of solid municipal and solid domestic waste. Also, the claimed invention provides a reduction in energy and operating costs and a decrease in the environmental burden on the environment. Also, the claimed method provides an economically profitable and environmentally friendly technology for all-season neutralization and disinfection of both young and old filtrate of household solid waste (HSW) or municipal solid waste (MSW) landfills, as well as neutralization and disinfection of the resulting residue (sediment) in a flow-through mode. The inventive method is carried out in a flow-through mode and provides reagent-free processing and neutralization, cleaning and disposal of landfill filtrate with simultaneous neutralization of the released residue. The method includes the stages of polyelectrode sedimentation and separation of wastewater and elements dissolved in it, ultrafiltration and macrocapillary membrane filtration and separation of water into retentate and permeate, treatment of water with thin acoustic fields of extremely high frequencies (EHF), treatment of effluents with an electromagnetic variable field of low currents with adjustable frequencies, treatment with highly saturated ionic phases of cold-plasma prominences, intermediate filtration in superfiltration blocks and final filtration in filter elements made of an alloy of boric ceramic lattice and titanium dioxide in a flow-through mode.

EFFECT: increase in the efficiency and quality of purification, including purification of water from a wide range of dissolved, emulsified and extracted pollutants, toxic complex inorganic and organic substances and salts of heavy metals in a wide range and with critical concentrations.
