[Removal of organic pollutants by adsorption cooperated with biodegradation in BAC].Huan Jing Ke Xue. 2007 Apr; 28(4):777-80.HJ
The determination measure for distribution of NOM removal by two mechanisms in BAC was established. In this method, the change in DOC and BDOC of inflow and effluent was used to evaluate the distribution and to determinate the effect of the different ozone doses on the adsorption and biodegradation in BAC. The ozonation increased the concentration of BDOC in 0.12 - 0.54 mg/L with ozone dose of 2 - 8 mg/L and BAC filtration decreased concentration of BDOC to 0.23 - 0.31 mg/L. Moreover the biodegradation distribution to remove the organic pollutants increased from 46% to 89% with ozone dose of 2 - 8 mg/L.
