The dust shield (10) includes a pattern of electrodes (12) made from a conductive ink, such as silver ink or carbon ink, which is printed on a flexible substrate (14) made from a thermoplastic film. A cover sheet (16) of thermoplastic film is laminated to the substrate (14) over the pattern of electrodes (12). The electrodes (12) are adapted for attachment to a single phase or multi-phase alternating current signal, which generates an electric field for repelling dust particles.

Abstract: Provided is a method for reducing COD of wastewater with improved utilization efficiency of ozone. The method achieves an objective by adding agents for removing hydroxyl radical scavengers produced by base-catalyzed ozone advanced oxidation to wastewater. The addition of calcium ion, barium ion, etc. to a base-catalyzed ozonation system makes the hydroxyl radical scavengers form precipitates, separated from water and lose the capability of scavenging hydroxyl radicals, thereby enhancing ozone utilization efficiency. Furthermore, calcium ion, barium ion, etc. form precipitates with partial organic acids yielded in the wastewater ozonation and are separated from water, hence diminishing ozone consumption and indirectly improving the ozone utilization efficiency in the wastewater treatment.
