Abstract

This laboratory study determined the composition of the off-gas afterwet oxidation (WO) of trinitrotoluene (TNT) red water, and monitored bacterial toxicity of treated waste. The amount of sulfate concentration in the treated sample is much higher than the sum of the measured inorganic sulfate and the organic sulfur associated with the dinitrotoluene sulfonates initially present in the raw red water. This indicatesthe presence of other unidentified S-containing organic compounds in red water. The nitrogen analyses indicate a significant NH4+ concentration (32 mg N/1) in treated waste and a high N-2 concentration (14.6%;net increase of 4.6%) in the off-gas. The toxicity results indicate that the WO-treated red water exerts toxic effects on Acinetobacter andNitrosomonas growth, but has less impact on activated sludge. Furthermore, treated samples at 340 degrees C appear to exhibit a more inhibitory effect on both Acinetobacter and Nitrosomonas than those treated at 260 degrees C.
