Abstract:The treatment of ammonia nitrogen waste water by decompression-volatilization was investigated in this paper . The influence of factors such as pH,temperature,time and degree of vacuum) on the results was discussed. The result showed that under the condition of pH=9、temperature(60℃)、time(60 min)and degree of vacuum(0.07 MPa),the removal of ammonia nitrogen could reach more than 80%,which was heplful to development of tantalum-niobium new wastewater treatment technology.
Key words:ammoniacal nitrogen;decompression-volatilization;tantalum-niobium wastewater
