%X The effect of NO-3 on para-chloronitrobenzene(p-CNB) reduction was investigated under the conditions of sufficient substrate and insufficient substrate with batch experiments due to the combined pollution of p-CNB and NO-3.Ethanol was used as co-substrate.Both p-CNB reduction and NO-3 reduction proceeded successfully with sufficient substrate.However,p-CNB reduction was competitively inhibited by NO-3 when substrate was insufficient(COD=100 mg/L).The inhibiting effect enhanced as the NO-3 concentrations increased.p-CNB reduction rate decreased by 20% and 54% when compared to the control,as initial NO-3 concentrations were 150 mg/L and 300 mg/L,respectively.Nitrite accumulation was also observed with a concentration of 33.68 mg/L and 44.92 mg/L in the above tests.It indicated that the effects of co-substrate and nitrate should be taken into account when anaerobic biological treatment is applied for the remediation of chloronitrobenzenes contaminated waters.
