Spent aircraft deicing fluid as external carbon source for denitrification of municipal wastewater: from waste problem to beneficial use

摘要

Use of deicing chemicals at airports is necessary to ensure passenger safety during winter operation. traditional aircraft and runway deicing and anti-icing procedures create runoff that locally causes major pollution problems. The use of deicing and anti-icing chemicals is expected to increase, and it is therefore importnat to find alternative technologies and strategies that will minimize the environmental impacts of deicing activities. Treating airport storm water runoff at a nearby municipal wastewater treatment plant (WWTP) is a possibility. Normally, however, the WWTP is not designed to handle the very high organic loads from deicing chemicals, and this may cause unstable operation and poor effluent quality.
