Направления использования фильтрата при производстве гипса из осадков коагуляции природных вод

Аннотация

Одним из важнейших аспектов разрабатываемых в настоя­щее время технологий является то, что они должны быть безотходными либо малоотходными. При производстве синтетического гипса из осадков коагуляции природных вод и отходов серной кислоты образуется кислый фильтрат, который по своему составу содержит соли Mg, Na, Ca и Fe. Предложена и проработана возможность использования фильтрата с высоким содержанием железа для получения магнитных сорбентов при удалении нефтепродуктов из водных сред, а также для получения фотокаталитических материалов при деструкции растворенных органических веществ. Исследование показало, что магнитные сорбенты обладают нефтеемкостью до 2 г/г. Полученные фотокаталитические материалы обладают также высокой эффективностью фотодеструкции красителя (кислотного телона синего) на уровне 80% при времени обработки 60 минут.
