METHOD OF CARRYING OUT MECHANICALLY DECREASED SEDIMENTS OF SEWAGE WATERS Russian patent published in 2018 - IPC C02F11/12 C02F11/18 C02F1/28 B09C1/00 

FIELD: processing.

SUBSTANCE: group of inventions can be used in the field of processing sewage sludge to reduce danger class of mechanically dehydrated sediments during their subsequent disposal. Technology of method comprises preparing mixture of adsorbent and inert material, mixing active mixture and mechanically dehydrated sewage sludge, and drying mixture to humidity of 0–20 % to obtain final mixture. Aquaionite is used as adsorbent, mass of adsorbent being not less than 3 % of absolutely dry mass of mechanically dehydrated sewage sludge. Sand is used as inert material, while mass of inert material is 15–450 % from mass of mechanically dehydrated sewage sludge. Processing of rocky inclusions of inert material includes determination of moisture content of inert material, crushing of rocky inclusions and their screening.

EFFECT: in some embodiments, dry or wet sand is used as inert material, reactant is added from humate to active mixture, and mixture is diluted with inert material before and after drying.
