Wastewater treatment of petroleum products: experience of application of visible light photocatalyst based on the bismuthates of the alkaline earth metals

541.128.3Abstract
The article investigates the catalytic properties of visible light photocatalysts consisting of bismuthates of the alkaline earth metals and bismuth oxide. Due to the high sensitivity to radiation in the visible range, these catalytic compositions are promising materials in terms of their use in water purification from organic pollutants. In this article we present for the first time the experimental data on the testing of new photocatalysts based on the bismuthates of the alkaline earth metals on drains of the real organizations. The test performance was carried out on wastewaters provided by the "Dalnefteprovod" company and the firehouse administration of the Civil Defence, Emergencies and fire safety of the Khabarovsk Territory. It is shown that regardless of the underlying alkaline earth metal, all synthesized catalyst compositions exhibit high catalytic activity, which is manifested in a rapid decrease in the concentration of petroleum products in wastewater.
