Abstract

Настоящее изобретение относится к удалению органических веществ и мышьяка из природной воды с помощью полимеров алюминия и кремнезема, в частности, к очистке сырой воды с повышенным содержанием гумусовых веществ и мышьяка при исключительно неблагоприятных условиях очистки, таких как высокая ионная сила и пониженные температуры. С помощью инновационной усовершенствованной технологии очистки, раскрытой в настоящем патенте, достигается удаление гумусовых веществ и мышьяка и уже на стадии коагуляции и отделения осадка обеспечивается стандарт качества питьевой воды при исключительно высоком содержании гумусовых веществ, например, в сырой воде из источника водоснабжения г. Зреньянин, при расходе KMnOсвыше 50 мг/дми общем содержании As свыше 0,100 мг/дм. При высоком содержании различных соединений мышьяка в сырой воде отдельно либо в сочетании с высоким содержанием гумусовых веществ требуется их удаление с применением наиболее приемлемых технико-экономических и экологических решений. За счет применения инновационной технологии были достигнуты наиболее оптимальные условия одновременного удаления обоих типов загрязнений из сырой воды. Способ как таковой включает оптимизацию условий очистки: путем нейтрализации заряда гумусовых молекул, обеспечения оптимального рН и дозировок неорганических полимеров и их соотношений при соответствующих энергетических условиях хлопьеобразования и далее путем применения различных процессов отделения, т.е. либо классических систем отделения (седиментация или флотация путем фильтрования через песок) либо процессы мембранного отделения.The present invention relates to the removal of organic matter and arsenic from natural water using aluminum and silica polymers, in particular, the purification of raw water with a high content of humic substances and arsenic under extremely unfavorable purification conditions, such as high ionic strength and low temperatures. With the help of an innovative improved purification technology disclosed in this patent, humus substances and arsenic are removed, and already at the stage of coagulation and sediment separation a standard of drinking water quality is provided with an exceptionally high content of humus substances, for example, in raw water from a water source in Zrenyanin at a consumption of KMnO more than 50 mg / dmi total content of As over 0,100 mg / dm. With a high content of various arsenic compounds in raw water, alone or in combination with a high content of humic substances, their removal is required using the most appropriate technical, economic and environmental solutions. Through the use of innovative technology, the most optimal conditions for the simultaneous removal of both types of pollution from raw water were achieved. The method itself includes optimization of the purification conditions: by neutralizing the charge of humus molecules, ensuring the optimum pH and dosages of inorganic polymers and their ratios under appropriate energy conditions for flocculation and further by applying various separation processes, i.e. either classical separation systems (sedimentation or flotation by filtration through sand) or membrane separation processes.
