摘要
采用铁炭还原催化/生物降解/臭氧联合工艺处理常山某化工厂硝基氯苯类生产废水,运行结果表明,系统对高浓度有机污染物去除效果显著,抗冲击负荷能力强,剩余污泥产生量少,运行费用低。当废水进水COD为1939.9mg/L、硝基苯类为40.4mg/L、苯胺类为84.1mg/L时,处理后出水COD、硝基苯类、苯胺类浓度分别为78.6、0.28、0.11mg/L,达到《污水综合排放标准》(GB8978—1996)的二级标准。
The combined process of iron-carbon reduction, biological degradation and ozone was used to treat chloronitrobenzene wastewater from a chemical plant in Changshan. The results indicate that the system has significant removal efficiency of high-concentration organic pollutants, strong resistance to shock loads, less excess sludge production and low operation cost. When the influent concentrations of COD, nitrobenzene and phenylamine are 1 939.9 mg/L, 40.4 mg/L and 84.1 mg/L respectively, their effluent concentrations after treatment are 78.6 mg/L, 0.28 mg/L and 0.11 mg/L respectively, which meets the second level criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 - 1996）.
