Catalytic methods of wastewater treatment from the production of styrene and propylene oxide at the operating enterprise
Tighter environmental regulations forced the company to pay proper attention to solving the problem of high-quality treatment of wastewater at the discharge of their in natural bodies of water. The problem here is that the composition of waste is multicomponent and unstable, as well as the economic costs of processing plants and the reagents are significant. In addition, a variety of purification systems of treated water for chemical components in the composition and method of their origin causes the need for research based on specific conditions of production enterprises. The article investigates the optimal conditions for the catalytic decomposition of peroxide compounds waste water production of styrene and propylene oxide, providing increased availability for biodegradation of waste. The possibility of degradation of peroxides in neutral and acidic media wastewater in presence of a catalyst. The thermal decomposition of peroxide compounds using ferric ions Fe (II). The proposed methods allow the destruction of peroxides to achieve a high degree of purification of waste water from these components, and produce high-quality biological refining of manufacturing water production of styrene and propylene oxide by means of organic compounds biodegradation.
