摘要
Abstract
By lime‐chlorinated lime‐ferrous sulfate process and lime‐polymeric ferric sulfate‐PAM process ,removal of arsenic from the arsenic‐containing acidic wastewater from a gold metallurgical plant was researched .The results show that the wastewater can be emission on standard after being treated by the two processes but the later is with lower cost .The best conditions are pH of 9 -10 , m(PFS)/m(As)of 15/1 ,PAM addition of 12 g/m3 ,agitating time of 10 min ,settling time of 1 .5-2 .0 h .关键词
