APPARATUS FOR THE PURIFICATION OF CYANIDE-CONTAINING WASTE WATER

摘要

The apparatus for the purification of cyanide-containing waste water provides the possibility to clean waste water with high cyanide and disperse phase content. The apparatus includes the bioreactor and stirring unit placed in the bioreactor. At least one cultivator for microorganisms (27) is connected with the bioreactor and at least one sorption chamber (28) over which a drainage screen (34) with inclined to the horizontal at an angle 20-40 DEG is installed; said sorption chamber is equipped with bubblers (31) and stirring unit (32) being an airlift. The bioreactor is made in the form of tank (1) which is fitted with heating elements (7) and bubblers (8) and has in its walls inlets (2) to supply a treated cyanide-containing waste water in the bioreactor, inlets (3) to introduce microorganisms in the bioreactor, outlet (4) to discharge the cyanide-containing waste water and microorganism mixture from the bioreactor, and stirring unit (6) of the bioreactor is an impeller pump or airlift.
