摘要：

This study evaluated a pilot-scale nonthermal plasma (NTP) advanced oxidation process (AOP) for the degradation of trace organic compounds such as pharmaceuticals and potential endocrine disrupting compounds (EDCs) The degradation of seven indicator compounds was monitored in tertiary-treated wastewater and spiked surface water to evaluate the effects of differing water qualities on process efficiency The tests were also conducted in batch and single-pass modes to examine contaminant degradation rates and the remediation cap abilities of the technology, respectively. values for electrical energy per order (EEO) of magnitude degradation ranged from <0 3 kWh/m(3)-log for easily degraded compounds (e g, carbamazepine) in surface water to 14 kWh/m(3)-log for more recalcitrant compounds (e g., meprobamate) in wastewater Changes in the bulk organic matter based on UV(254) absorbance and excitation-emission matrices (EEM) were also monitored and correlated to contaminant degradation These results indicate that NTP may be a viable alternative to more common AOPs due to its comparable energy requirements for contaminant degradation and its ability to operate without any additional feed chemicals (C) 2009 Elsevier Ltd All rights reserved
