- Abstract:
-
Anaerobic baffle reactor was used to treat o-nitroaniline wastewater with sucrose as matrix at medium temperature (37°C). The sludge was domesticated by the method of low load and high removal rate, the COD concentration was determined by the standard potassium dacmate method, and the concentration of o-nitroaniline was determined by naphthalene ethylenediamine azo photometry. The results showed that when the concentration of o-nitroaniline in the influent was less than 8 mg/L, the COD concentration was 1200mg/L and the HRT was 1 d, the reactor operated stably, and the removal rate of o-nitroaniline and COD removal rate reached 84% and 85%, respectively.
