活性污泥微生物对苯胺废水的降解研究
Study on Degradation of Aniline by Activated Sludge Microorganism
摘要
Abstract
Sequencing batch reactor (SBR) was used to cultivate and acclimate activated sludge,unacclimated and salt acclimated sludge were taken out from the reactor to study the degradation effect of microorganisms on aniline by batch experiments.The results showed that after the sludge acclimated to 10 g NaCl/L,removal efficiencies of COD,NH4+-N and TN were 86.5%,97.6% and 96.4% in the SBR,respectively.The results in batch experiments showed that the degradation rate of aniline increased gradually with the increase of initial concentration of aniline.In the test with unacclimated sludge and without salt,the degradation rate of aniline was higher than that in the test with salt acclimated sludge under saline conditions.In the test without aniline addition,degradation rates of COD and NH4+-N were much higher compared to the condition of adding aniline.The degradation rates of both COD and NH4+-Nwithunacclimated sludge and without salt was significantly higher than that with acclimated sludge and with salt.When adding aniline,the COD degradation rate increased gradually with the increase of the concentration of aniline.At the end of experiments,both NO2--N and NO3--N were found in acclimated sludge under saline conditions,however,only NO3--N was detected in the test with unacclimated sludge.关键词
