硝酸盐还原条件下对氯硝基苯的生物还原转化
Effect of nitrate reduction on the microbial reductive transformation of para-chloronitrobenzene
摘要
Abstract
The effect of NO3 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 NO3-. Ethanol was used as co-substrate. Both p-CNB reduction and NO3- reduction proceeded successfully with sufficient substrate. However, p-CNB reduction was competitively inhibited by NO3- when sub- strate was insufficient （COD = 100 mg/L）. The inhibiting effect enhanced as the NO3- concentrations increased. p-CNB reduction rate decreased by 20% and 54% when compared to the control, as initial NO3- 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 con- taminated waters.关键词
