METHOD AND INSTALLATION FOR CLEANING WATER CONTAINING HALOGENATED ETHYLENE Russian patent published in 1997 - IPC

FIELD: water purification. SUBSTANCE: invention particularly relates to cleaning water containing halogenated ethylene, for example, ground water to produce process water and drinking water. Water is treated with ozone and high-energy, in particular, ionizing irradiation. Water (i) containing along with halogenated ethylene also other constituents and/or harmful substances affecting mainly quality of drinking water, and/or (ii) water containing these substances, and/or (iii) water preliminarily treated with ozone, and/or (iv) water saturated with ozone, in particular, ground water is subjected to electron irradiation in stream, ozone concentration in water being adjusted in such a way as to provide ozone concentration in water immediately leaving irradiation zone to be at least 0.1 mg/l. Installation involved contains electron accelerator and chamber for electron irradiation of water, ozone detection sensor disposed immediately after the chamber, which is connected through executive element to ozone supply controlling element disposed in pipeline supplying chamber with nonirradiated water. EFFECT: provided treatment of large amount of water with high degree of contamination degradation. 9 cl, 1 dwg, 2 tbl
