C/N和pH值对高温好氧反硝化菌产N_2O的影响研究
Effect of C/N ratio and pH on nitrous oxide production of themophic aerobic denitrifier
摘要
Abstract
Under different C/N ratios and pH,the experiment investigated the nitrogen removal efficiency and nitrous oxide production of thermophic aerobic denitrifier strain TAD1.The results indicated that the nitrogen removal efficiency and nitrous oxide production were influenced by C/N ratio and pH.The nitrogen removal efficiency was up to 99.12%,and nitrous oxide production was only 3.35×10-2 mg/L,N2O conversion rate was 0.045%,the major end production of denitrification was nitrogen under the optimum C/N ratio of 9 and pH 7.Additionally,acidity was not favorable for aerobic denitrification between 6 and 8 in pH,the nitrogen removal efficiency was 83.18% with pH 6,and the production of nitrous oxide was up to 13.88×10-2 mg/L,which was 4.14 times higher than that of pH 7 and 5.07 times higher than that of pH 8.关键词
