Abstract

FIELD: waste water purification. SUBSTANCE: in order to purify waste water from formaldehyde, waste water is treated with acidic granulated adsorbent composed of clay minerals with lamellar and lamellar-band structure followed by neutralization and recovery of worked out adsorbent with ammonium carbonate solution at pH 9.0-10.0 and temperature of reaction mixture 30-40 C. EFFECT: provided purification means for wastes from wood-working factories.
