AI Technical Summary
Existing wastewater treatment methods for bitter almond detoxification are complex and costly, making it difficult to efficiently and safely remove hydrocyanic acid, leading to water waste and environmental pollution.
Apricot shells were used as activated carbon adsorbents. Wastewater was treated by connecting apricot shell adsorption tanks in series. Hydrofluoric acid content was monitored using an online hydrofluoric acid detector. After adsorption saturation, the apricot shells were carbonized to produce wood vinegar and ammonium salts, thus enabling the reuse of wastewater.
It achieves efficient adsorption and purification of hydrogen cyanide, reduces the content of toxic substances in wastewater, and the generated activated carbon can be reused, saving water resources, simplifying the operation process and reducing maintenance costs.
