FIELD: reagent-free biological deferrization of water from underground sources; applicable in water treatment for service needs. SUBSTANCE: mine plant for water biological defferization has vertical body 1 with branch pipes 2,3 and 4 for supply and discharge of media and with horizontal downcomer slot partitions 5 which form tiers with liquid-air hollow 6 in the lower part and air-liquid hollow 7 in the upper part which is made with tangential air inlet 8 to spiral channel 9 formed by insert 10 secured from the bottom to downcomer partition 5. Spiral insert 10 is made with dispersing rods 11. In this case, slots of downcomer partition 5 coincide, by direction of outlet holes, with that of outlet hole of tangential inlet 8. Liquid-air hollows 6 are provided with AZIN substance 13 whose density is lower than the density of water (expanded clay aggregate, expanded perlite, modified zeolite, etc.). Lower liquid-air hollow 6 is communicated with microfilter 14 and biomass of iron bacteria with centrifugal disintegrator 15, and the latter, by disintegrate, is communicated with upper air-liquid hollow 7. Tangential inlets 8 are communicated with air header 16 of air blower 17. EFFECT: higher efficiency. |
