External Carbon Source

By treating real domestic sewage which is low C/N in A/O process ，results showed that different removal rates occured under different organic loadings、internal reflux ratio (R) without external carbon source . It was demonstrated that with the improvement of organic loading, F/M improved from 0.22kg/(kgMLSS•d) to 0.28kg/(kgMLSS•d), removal rates of TN and COD were improved by 4.84% and 16.55% respectively. Because lower C/N, TN and COD removal had no obvious enhancement by elevating R from 150% to 250% with organic loading is 0.28kg/(kgMLSS•d).

Heterotrophic Denitrification

The effects of external Carbon-source (both type and C/N ratio) on heterotrophic denitrification were evaluated. Glucose, methanol and ethanol were chose as the C-sources, and the optimal C/N ratio of ethanol was decided as 2 while that of glucose and methanol is 6.5 and 2.5 respectively. Compared with methanol and glucose, ethanol is more efficiency, its average denitrifying rate was 1.2483 mg/g•h.This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications.
