TiO_2和活性炭协同处理制药废水的研究

TREATMENT OF PHARMACEUTICAL WASTEWATER BY THE SYNERGISM OF TiO_2 AND ACTIVATED CARBON

论证了在固有TiO_2的光催化反应器中，加入活性炭和Fenton试剂的可行性。实验结果表明，同运用其它处理手段相比，该体系的CODcr去除率显著提高，降解时间亦随之减少。当pH=3，[H_2O_2]=12mg／L，[H_2O_2]／[Fe^(2+)]=20，活性炭=10g／L时，达到国家工业废水一级排放标准。

In TiO_2 fixed film photocatalytic reactor ,the feasibility of the addition of activated carbon and Fenton agent was studied .This system was proved to be most effective for CODcr removal and the decrease of reactor time than others. At pH=3, [H_2O_2]=12mg/L, [H_2O_2]/[Fe^(2+)]=20,AC=10g/L, the wastewater reached the first class standard of the national industrial discharge.
