Research on photocatalytic degradation of organic pesticide wastewater by using TiO/GeO composited film
TiO/GeO复合膜光催化氧化降解农药废水的研究

A kind of new TiO2/GeO2 composited film in circular shape reactor was developed. The experiment was made on the degradation of physico-chemically treated organic pesticide wastewater by using this reactor. The results showed that the optimal conditions were zinc slice plating TiO2/GeO2 composited film, pH = 6.7, and 400 mg/L of H2O2. The conditions and affecting factors of photoassisted catalytic oxidation were determined through the experiment. It is shown that COD in the treated effluent was reduced to 57.0 mg/L, and all of organic pollutants were degraded into some small inorganic molecules, and thus reaching grade 1 of integrated wastewater discharge standard.
