摘要
Abstract
For the characteristics of a petrochemical wastewater with high nitrification inhibition,the performances of eliminating nitrification inhibition by Fenton oxidation and Fe-C microelectrolysis pretreatment are compared.Fenton oxidation can eliminate the nitrification inhibition effectively while Fe-C microelectrolysis can't.Concerning on Fenton oxidation,the experiment conditions are optimized by single-factor experiment:pH =3,H2O2∶ CODCr∶ Fe2+ =1 ∶ 1∶ 0.55 (mass ratio),reaction period =20min.The activity of nitrifying bacteria increases substantially.The nitrification inhibition decreases from 87％ to 3.6％,and the CODCr concentration decreases from 674mg/L to 414mg/L.关键词
