Title : Combined electron-beam and biological treatment of dyeing complex wastewater. Pilot plant experiments


Abstract

   Pilot plant (output 1000m3 day1) with ELV electron accelerator (energy 1 MeV, beam power 40 kW) is in operation from October 1998. Combined electron-beam and biological treatment was used for purification of dyeing complex wastewater under continuous flow conditions. The main results of pilot-scale experiments consisted in the fact that decrease in total content of pollutants after biological treatment was substantially influenced by preliminary electronbeam treatment (mainly, because of radiolytic conversions of terephthalic acid being a main pollutant of the wastewater). Equal purification degree corresponded to 17 h of bio-treatment without preliminary irradiation and about 8 h of bio-treatment with preliminary electron-beam treatment at absorbed dose 1–2 kGy.
