Ltd.----Design of Treatment Process for Cyanide Wastewater by Zhongshan Haomin Electroplating Co. Ltd.AbstractCyanide is one of the priority pollutants to be treated by the environmental protection agencies of various countries. Electroplating wastewater directly discharged without process treatment and other steps will not only cause the waste of precious metals and water resources, but also cause the pollution of rivers, lakes and oceans that receive the discharged wastewater, thus affecting the water environment. Electroplating wastewater usually includes cyanide wastewater, chromium wastewater, acid-base wastewater and heavy metal 北京理工大学珠海学院 2020 届本科生毕业设计wastewater. In this paper, we will compare a variety of treatment schemes of electroplating cyanogen wastewater, decide to choose alkaline chlorination method to treat the electroplating cyanogen was...
