FIELD: technological processes.
SUBSTANCE: invention relates to acid sludge processing. Method of treating acid sludge involves depositing on surface of granules of microporous sedimentary rock of amorphous silica one or more layers consisting of acid sludge, micronized material containing calcium oxide, and micronized microporous sedimentary rock of amorphous silica.
EFFECT: production of fuel granules, at that they have high melting point (higher, than 400 degrees Celsius), which provides dispensing granular tar using system of solid fuel supply, also provides for use of fuel granules in boilers with circulating boiling bed.
