Summary:FIELD: waste water treatment. SUBSTANCE: afterpurification of household and industrial waste waters considerably increases removal of organics (up to 50%) and suspended particles (up to 95%) and involves filter composition consisting of adsorbent-catalyst on mineral carrier and supporting bed wherein adsorbent-catalyst contains catalytically active components and clay, wt. -%: pyrite ashes, 20-25; sodium tetraborate, 1.5-2.0; glass, 1.5-2.0; petroleum coke, 1.0-1.5; and clay, the balance. EFFECT: enhanced waste water treatment efficiency. 3 tbl
