Водопроводные осадки: утилизация при производстве строительных материалов и в сельском хозяйстве. Альтернативные коагулянты (обзор)

Аннотация

При производстве строительных материалов и в сельском хозяйстве могут быть использованы значительные объемы водопроводных осадков, обеспечивая при этом их утилизацию. Следствием применения осадков в строительной промышленности может стать существенная экономия традиционных сырьевых материалов без ухудшения качества продукции. Налаженных поставок водопроводных осадков на предприятия стройиндустрии, однако, пока не происходит, и в качестве основной причины называют непостоянство их состава. Вместе с тем достигнутые результаты свидетельствуют о значительных усилиях, предпринимаемых в этой области. На основе использования водопроводных осадков разработаны технологии производства цемента, строительного раствора, бетона, кирпича, кровельной черепицы, керамических изделий. Сельскохозяйственное применение водопроводных осадков считается наиболее доступным и масштабным вариантом их утилизации. Содержание органики и тяжелых металлов в водопроводных осадках достаточно ограниченно, что выгодно отличает их от осадков сточных вод и позволяет классифицировать как безопасные. К настоящему времени в целом ряде стран проведены многолетние масштабные эксперименты по использованию водопроводных осадков для корректировки содержания растворимого фосфора в почвах, для связывания растворимых форм мышьяка и хрома и корректировки содержания микроэлементов. Кардинальное решение проблемы водопроводных осадков должно быть связано с уменьшением их образования в процессе водоподготовки. В этом направлении ведется поиск альтернативных коагулянтов, прежде всего растительного происхождения. Достигнутые результаты позволили провести опытно-промышленные испытания водного экстракта семян масличного дерева Moringa oleifera в качестве коагулянта при очистке поверхностной воды.
