Abstract： |
The invention discloses a disposing method of cyanic waste water through chemical sediment-gamma-ray radiating method, which comprises the following steps: combining zinc salt sediment and gamma-ray decomposing cyanide method; adding zinc salt in the cyanic waste water; sedimenting and recycling most of cyanide; decomposing residual cyanide through gamma-ray to make waste water reach draining standard. |
