Abstract
PURPOSE: To decrease COD components and to make cyanide harmless, by heating and concentrating the waste water containing acetontrile.cyanide compound from the bottom of water separation tower and COD components maintaining at a specific pH value and treating condensed liquid at a high temperature under limited condition after condensing distilled vapor.
CONSTITUTION: Waste water containing acetonitrile.cyanide compound from the bottom of water separation tower and COD components, is heated and concentrated maintaining pH at 9 or more, at the time of refining unsaturated nitrile from ammoxidation reaction gas of olefin. Next, distilled vapor is condensed and a high temperature treatment is carried out at a temperature of 120°C or more maintaining pH of condensed liquid at 9 or more, staying sufficient time to make contained cyanide harmless. Remaining liquid carried out the above-mentioned heating concentration, is contained a high concentration COD components and in case of being concentration degree ten or more, the above liquid is able to use as fuel because of spontaneous combustion. Accordingly, it is made possible to make harmless by incineration treatment.
