脱氮硫杆菌对废水中硫氮的脱除
DOI: 10.3724/SP.J.1145.2013.00175, PP. 175-178
Keywords: 脱氮硫杆菌,硝酸盐,硫氮废水,去除率
Abstract:
为脱除废水中高浓度的硫氮，首先对脱氮硫杆菌（thiobacillusdenitrificans）的生长曲线和驯化期间营养液ph的变化进行了测定，确定了脱氮硫杆菌合适的使用条件.然后检测了接菌后废水中的s2-浓度控制在400mg/l时合适的硫氮比以及脱氮硫杆菌对no3-的去除率.结果表明，处理富含硫氮的废水时，当硫氮比控制在5:3、s2-浓度控制在400mg/l时，脱氮硫杆菌对no3-的去除率可达63.19%，同时s2-转化成硫酸盐或可回收的单质硫，使废水的硫氮污染得到了有效的控制.图6表1参16
