Question

The aerobic degradation of 2,4-DNT (C7H6N2O4) is as follows: C7H6N2O4 + 5.62O2 → 5.17 CO2 + 1.63NO2- + 1.63H+ + 0.90H2O + 0.37C5H7O2N If 1000 lbs/batch of soils contaminated with 900 mg/kg 2,4-DNT (soil density = 125 lb/ft3) is treated in a batch-wise operation in a bioslurry reactor to degrade 2,4-DNT, the stoichiometric oxygen needed per batch is ____ lb/batch. Assume oxygen demand comes only from 2,4-DNT, and no significant other organic compounds are present in this soil.
