Title : Electron beam treatment of textile dyeing wastewater: operation of pilot plant and industrial plant construction
A pilot plant for treating 1000m3/day of dyeing wastewater with
e-beam has been constructed and operated since 1998 in Daegu, Korea
together with the biological treatment facility. The wastewater from
various stages of the existing purification process has been treated
with an electron beam in this plant, and it gave rise to elaborating the
optimal technology of the electron beam treatment of wastewater with
increased reliability for instant changes in the composition of
wastewater. Installation of the e-beam pilot
plant resulted in decolorizing and destructive oxidation of organic
impurities in wastewater, appreciable reduction of chemical reagent
consumption, in reduction of the treatment time, and in increase in the
flow rate limit of existing facilities by 30–40%. Industrial plant for
treating 10,000m3/day each, based upon the pilot experimental result, is
under construction and will be finished by 2005.
