Abstract
Способ обеззараживания воды в отношении индикаторных, потенциально-патогенных и патогенных бактерий, включающий отбор проб, оценку качества исходной инфицированной воды и обеззараживание нерастворимыми в воде гетерогенными сенсибилизаторами, отличающийся тем, что в качестве нерастворимых гетерогенных сенсибилизаторов используют сенсибилизаторы, нерастворимые в воде на основе фталоцианинов, привитых к аминопропилированному силикагелю в концентрациях от 1 до 10 г/дм, в структуре активной фазы которых содержатся фталоцианины металлов, при концентрации активной фазы от 1,5 до 10 мкм/г, при различных электрических зарядах, с различным диаметром пор носителя, выбранные гетерогенные сенсибилизаторы вводят в инфицированную воду и выдерживают ее в течение 30 мин в темноте с последующим освечиванием на расстоянии 10 см электрической лампой со световым потоком 9100 lm, при активном барботировании кислорода воздуха в течение 1-2 ч при температуре 22-25°С, затем после осаждении сенсибилизаторов в течение 5 мин отбирают пробы воды из надосадочной жидкости, взвеси и осадка, производят посевы воды на плотные дифференциальные питательные среды прямым посевом и методом мембранной фильтрации, посевы инкубируют в течение 24 ч при температуре 37°С в термостате с последующим подсчетом выросших колоний на поверхности питательных сред и вычисляют эффективность обеззараживающего действия гетерогенных сенсибилизаторов на основе фталоцианинов, привитых к аминопропилированному силикагелю, при этом оценивают эффективность обеззараживания как высокую при значении ≥99,99, среднюю при значении от 80,9 до 99,98, низкую при значении <80,9.A method of disinfecting water against indicator, potentially pathogenic and pathogenic bacteria, including sampling, assessing the quality of the source of infected water and disinfecting with water-insoluble heterogeneous sensitizers, characterized in that sensitizers that are insoluble in water based on phthalocyanines are used as insoluble heterogeneous sensitizers grafted to aminopropylated silica gel in concentrations from 1 to 10 g / dm, the structure of the active phase of which contains metal phthalocyanines , at a concentration of the active phase from 1.5 to 10 μm / g, at various electric charges, with different carrier pore diameters, the selected heterogeneous sensitizers are introduced into infected water and kept for 30 minutes in the dark, followed by irradiation at a distance of 10 cm with electric a lamp with a light flux of 9100 lm, with active bubbling of atmospheric oxygen for 1-2 hours at a temperature of 22-25 ° C, then after sedimentation of sensitizers for 5 minutes, water samples are taken from the supernatant, suspension and sediment, sowing water on solid differential nutrient media by direct sowing and membrane filtration, the crops are incubated for 24 hours at a temperature of 37 ° C in a thermostat, followed by counting the grown colonies on the surface of the culture media and calculate the effectiveness of the disinfecting effect of heterogeneous sensitizers based on phthalocyanines grafted to aminopropylated silica gel, and disinfection efficiency is assessed as high with a value of ≥99.99, medium with a value of 80.9 to 99.98, low with a value of <80.9.
