Biodegradability Enhancement of Papermaking Wastewater by Electron Beam Irradiation

Abstract:

Papermaking wastewater is one of six industry polluted sources. It generally contains various pollutants which can cause many problems during biological treatment. The biodegradability of papermaking wastewater was enhanced by electron beam irradiation with an activated sludge process. The value of the BOD5/COD ratio increased at a 20kGy dose. The non-biodegradable organic compounds were converted into biodegradable compounds. High organic removal efficiencies and high microbial activities were achieved in activated sludge process. The application of an integrated system can be a powerful process which contains electron beam irradiation and a biological treatment to papermaking wastewater.
