纳米铁-真养产碱杆菌柱实验去除硝酸盐
Denitration by nanoscale iron-alcaligenes eutrophus in column experiment
摘要
Abstract
In this study,experimental column equipment was established to explore the nitrate removal efficiency and the products under the conditions of different media,initial nitrate concentrations and flow rates.The results show that the complex obtained by mixed culture of nanoscale iron and alcaligenes eutrophus for 5 days prior to the experiment,achieves removal rate of 75% and the yield of ammonia is just 2.99 mg/L.This is the best removal effects among the 4 media,the rest of which were nanoscale iron,alcaligenes eutrophus,simplely mixed culture of fresh nanoscale iron and alcaligenes eutrophus.The degradation of the NO-3-N by the nanoscale iron-alcaligenes eutrophus achieved the best effect when initial concentration of nitrate was 32mg / L.The removal rate can achieve 78.9%,and the amounts of ammonia and nitrite generation were 2.34 mg/L and 2.89 mg/L,respectively,which was lower than that when initial concentrations of nitrate were 65 mg/L or 95 mg/L;the nitrate removal rate reached to 77% at the flow rate of 6.0 cm/h,and when the flow rate was controlled at 2.4 cm/h,the nitrite generation would lower to 0.34 mg/L.关键词
