APPARATUS FOR PURIFYING INDUSTRIAL AND STORM SEWAGE FROM TITANIUM-MAGNESIUM PRODUCTION Russian patent published in 2017 - IPC C02F9/08 

FIELD: wastewater treatment plants.

SUBSTANCE: invention relates to treatment of industrial sewage and storm sewage from titanium and magnesium production. Plant for cleaning of industrial and storm sewage water includes chambers, connected to each other in following sequence: oil trap 2 is connected to UV disinfection chamber 4 by pipe 3, passing through disinfection chamber and equipped with UV irradiation device 5 with wavelength of 250–270 nm, disinfection chamber is connected to waste water flow rate measurement chamber 6 by pipe 3, passing through chamber for measuring flow rate and equipped with acoustic flow meter 7, flow measurement chamber is connected via pipeline with filtration chamber 8 with sorption filler 9 of MIU-S2 type, and filtration chamber with sorption filler is connected via pipeline to collecting manifold 10 for purified waste water, and pump station 11 for pumping purified waste water is connected via pipeline on one side with collecting manifold for purified waste water, and on other side with recycled water supply network 12. Transmission rate of waste water via pipeline and UV disinfection chamber, chamber for measuring flow rate of waste water and filtration chamber with sorption filler is not more than 24 m³/h.

EFFECT: apparatus increases degree of purification of waste water from oil products (up to 0,05 mg/l), suspended substances (up to 7,55 mg/l) from impurities of nonferrous and rare metals, improves quality of recycled water used in cooling devices and equipment for titanium and magnesium production.
