| Abstract: |
| In order to locate the source of cyanide detected in main outfall of production wastewater of an iron chain factory, the production process, wastewater composition, wastewater treatment process, the materials, and test method are all analyzed. Consequently, it was found that cyanide was produced by the chemical reaction of the materials in the blackening process, which was testified by adjusting process route and this problem was resolved thoroughly. |
