摘要
Lime neutralization,chemical flocculent precipitation and organic compound denitrifier are applied in treatment of acidic and alkaline wastewater from Ta-Nb-W-Sn polymetallic ore separation.The re- moval rate of fluoride and ammonia nitrogen is above 99.9%,the removal rate of heavy metal ion is above 99%,and ammonia recovery rate is above 99.8%.The recycling of wastewater can be realized through the treatment process,and the recycled dilute aqua ammonia can be reused in the production process.The treat- ment process has good environmental and economic benefits.
