(5) СПОСОБ ОБЕЗЗАРАЖИВАНИЯ ВОДЫ ОТ ВИРУСОВ(5) METHOD FOR DISINFECTING WATER FROM VIRUSES
Изобретение относитс к очист .ке воды.. В насто щее ,врем дл очистки воды от различных примесей, в том чис ле и дл обеззараживани воды, к чис лу наиболее перспективных методов от нос т обратный осмос и. ультрафильтра цию. Известен способ обеззараживани в ды с содержанием АООО-8000 мг/л солей и искусственно зараженных бактериофагом Т1 и вирусом полиомиелита 7s с 2 -ав фильтрованием через ранные фильтры с размером пор 200 А на лабораторном стенде производитель ностью 10 л/сут, при предварительном опреснении этой воды электродиализом С 1 . Однако при использовании этого способа полного удалени из воды вирусов не полувено. Обеззараживание воды обратным осмосом требует высокого давлени , обычно 60-70 атм, что делает процесс технологически сложными неэкономным . Процесс ультрафильтрации, осуществл емый при невысоком давлении (2-10 атм), не позвол ет обеспечить полного обеззараживани воды от вирусов, что делает его непригодным подготовки питьевых, и очистки хоз йственно-бытовых вод. Наиболее близким к предпагаемрму по технической сущности способом обеззараживани воды ультрафильтрацией от вирусов, в том числе вирусов кишечной группы Коксаки вл етс способ, который состоит в фильтровании воды нерез полупроницаемую мембрану типа МВ-1-15, пройзводиteльнocтью 1600 л/м в сутки. Диаметр пор мембраны нм. Воду, инфицированную вирусом, профильтровывают через мембрану под давлением 0,50 ,15 атмр. Однако известный способ не позвол ет полностью очистить воду от виThe invention relates to the purification of water. At present, for purifying water from various impurities, including water disinfection, reverse osmosis and water are among the most promising methods. ultrafiltration. There is a known method of disinfection in dyes containing AOOO-8000 mg / l of salts and artificially infected with bacteriophage T1 and polio 7s virus with 2 –a filtering through early 200 A pore filters on a laboratory bench with a capacity of 10 l / day water electrodialysis With 1. However, when using this method of complete removal of viruses from the water, it is not half a dozen. Water disinfection with reverse osmosis requires high pressure, typically 60-70 atm, which makes the process technologically complex uneconomical. The ultrafiltration process, carried out at a low pressure (2-10 atm), does not allow for the complete disinfection of water from viruses, which makes it unsuitable for the preparation of drinking water, and for the purification of household water. The method of water disinfection by ultrafiltration from viruses, including the viruses of the intestinal group of the Coxsackie, is the closest to the preparation of the technical essence of the method. The diameter of the membrane pores nm. Water infected with a virus is filtered through a membrane under a pressure of 0.50, 15 atm. However, the known method does not allow the water to be completely purified from water.
