Ball Powder Production Wastewater Biological Treatability Studies.

摘要

Ball Powder (BP), a smokeless double-based propellant, is manufactured at Badger Army Ammunition Plant (BAAP), Baraboo, Wisconsin. The full-scale manufacture of this propellant produces a multicomponent wastewater containing, NG (nitroglvcerin), NC (nitrocellulose), EA (ethyl acetate), DBP (dibutylphthalate), DPA (diphenylamine), and 2-N-DPA (n-nltrosodiphenylamine). The last three compounds are categorized as EPA priority pollutants. In addition, NG, DBP, DPA, and 2-N-DPA are toxic and consequently limited to detection limits in the proposed Wisconsin Department of Natural Resources (W-DNR) limits. Presently in a caretaker status, mobilization plans require that BAAP be capable of treating its wastewater prior to discharge in the event of activation. In anticipation of possible renewed production activity, process wastewater (WW) treatment facilities are being modernized. An earlier study (contract No. DAAK 1 I-SS-D-0008) conducted on BP wastewater at BAAP reported that NG adversely impacted biological treatment processes resulting in an unacceptable system performance in terms of effluent BOD, TSS, NG, DPA and 2-N-DPA.
