For the single-stage circulation device process waste water of many Physical associating water treatment device, the flow process of water treatment is: first pending waste water is added (about 5L) in waste water tank during process, open corresponding valve, start the first liquid pump to start to carry out feed liquor process to ultrasonic UV ozone combined reactor, liquid pump is opened when solution reaches predetermined volumes in ultrasonic UV ozone combined reactor, now liquid pump and air pump have identical discharge capacity, (solution of flowing can by the complete submergence of plasma torch of dielectric barrier discharge ejector nozzle ejection to make solution low speeds flow, effectively to utilize the active particle of heating region), open air compressor pump, gas to be had flows through high-voltage power supply opens high-voltage power supply again, and now dielectric barrier discharge ejector nozzle exit has plasmatorch to spray, until system can steady running time, can the discharge parameter of regulator solution pump duty and high-voltage power supply.
Installing gas under meter on gas recycling duct between high-voltage power supply and dielectric barrier discharge ejector nozzle, in actual behaviour's process, first should start source of the gas, restart high-voltage power supply, to protect high-voltage power supply.By regulating the output duty cycle of high-voltage power supply internal controller, thus the change of the jet source discharge mode of control agent barrier discharge ejector nozzle ejection, and then affect yield of ozone and concentration, the organic matter degradation efficiency of the ultrasound-enhanced ozone reaction of final impact.
The collision frequency between duration of contact of solution and plasma body and molecules in solution can be changed by the flow velocity controlling liquid pump and air pump.Experiment shows, solution flow rate is one of important factor affecting organic matter degradation efficiency.When solution low speeds flow, the required activation energy of reaction is less, and intermolecular speed of reaction is determined by rate of diffusion; Along with the increase of solution flow rate, the collision frequency between the active substance in molecule and intermolecular and molecule and plasma body increases, and namely rate of diffusion is much larger than speed of reaction, and now intermolecular speed of reaction is determined by the activation energy that organism itself is required.Therefore, only control solution flow rate well, water treatment system just can be made to be in efficient, the most energy-conservation running status.Experiment shows, when the flow velocity of solution is 1.57 ~ 2.20m/s, in waste water, degradation effect of organic compound is the highest.By flow rate of liquid control unit, the liquid flow velocity of this device can be adjusted to 1.57 ~ 2.20m/s.
