摘要：
The possibility to remove herbicide diuron from waste waters without using chemicals by applying a novel hydrodynamic cavitation technology was investigated. Hydrodynamic cavitation device with a cavitator of Venturi type for waste water purification was constructed. The hydraulic characteristics of the device were determined: the dependences of flow and cavitation number on inlet pressure. The effect of cavitation number, number of passes, pH and temperature on the reduction of concentration of diuron in aqueous solution was examined. The kinetics and the kinetic model have been established and the kinetic parameters of diuron removal were calculated.
