Study on the Process of Removing Arsenic from Chlorin Washing Water and Arsenic Slag Beneficiation
Abstract:
Chlorin washing water can be neutralized with hydrochloric acid,and then remove arsenic by two stage process(adding lime in the first stage process and adding ferric sulfate in the second stage process to remove arsenic).After such treament,the content of arsenic in chlorin washing water can drop below 0.5mg/L,which reaches the state industrial sewage arsenic emissions standards.The content of arsenic in the first stage slag can be increased by secondary beneficiation.
