[0023] Example 1
[0024] Taking the nitrile-containing waste residue of a chemical plant as the treatment object, it is mainly the expired products of the iminoacetonitrile, anilinoacetonitrile, and hydroxyacetonitrile workshops, mixed with a small amount of ammonium sulfate and yellow blood sodium salt. The original test result: pH=3.5, total Cyanide 10400mg / kg, total sulfur 0.32%, total chlorine 0.019%, total 200 tons.
[0025] Use the method of the present invention to process the nitrile-containing waste residue:
[0026] Add dispersant Chinese medicine residue at 5% of the total nitrile waste residue, while adding slaked lime to adjust the pH of the material to 5.5, and leave it for 6 days after stirring. After pretreatment, the pretreated waste residue enters the rotary kiln according to different feeding methods after being compatible with other waste liquids through the menu. The temperature of the kiln tail of the rotary kiln is controlled to 750±20℃, and the waste residen...
