Claims (1)

Способ обезвоживания коллоидных осадков шлам-лигнина, включающий естественное замораживание осадка в холодное время года, с последующим оттаиванием, каскадным сбросом талой воды и уплотнением осадка в естественных условиях в теплый период времени года, отличающийся тем, что способ осуществляют в картах-накопителях, с созданием условия для естественного промерзания осадка посредством удаления снежного покрова и образующегося льда с поверхности карт-накопителей по мере их ообразования.The method of dehydration of colloidal sludge-lignin sediments, including the natural freezing of sediment in the cold season, followed by thawing, cascading discharge of melt water and compaction of sediment in natural conditions in the warm period of the year, characterized in that the method is carried out in storage cards, with conditions for the natural freezing of sediment by removing the snow cover and the resulting ice from the surface of the drive cards as they form.
