Description
Уплотненньш осадок нагревают до 18О200 С, выдерживают при этой температуре, отдел ют фильтрат и обезвоживают осадок. b таблт-ше приведены сравнительные данные по тепловой обработке осадка (избы чного активного ила влажностью 97,5%) лредпагвемым и известным способами.The compacted precipitate is heated to 18 ° 200 ° C, maintained at this temperature, the filtrate is separated and the precipitate is dewatered. b table shows the comparative data on the heat treatment of the sediment (surplus activated sludge with a moisture content of 97.5%) using conventional methods and methods known in the art.
