Rotating Biological Contactors for Munitions Wastewater Treatment

摘要

The report documents investigation of the applicability of aerobic rotating biological contactor (RBC) technology for secondary treatment of the wastestream of a facility manufacturing the explosives RDX and HMX. The synthesized wastestream contained high levels of formaldehyde and formic acid as well as the explosives RDX, HMX, and TNT. Several other organic contaminants were also present in lesser concentrations. It was found that the RBC was capable of removing 82% of the Chemical Oxygen Demand (COD) from the wastestream at loading rates of 2.3 lb of COD per 1000 sq ft of disc surface area per day. (Author)
