摘要 对某钢铁厂焦化废水浓水的生化出水进行深度处理研究,采用O_3/H_2O_2高级氧化及活性炭吸附法考察不同影响因素对COD和TN的去除效果。结果表明:O3接触时间25 min、H_2O_2投加量0.6 mL、pH值8~9、活性炭投加量为20 mg/L时,CODcr<40 mg/L、TN<10 mg/L,达到《炼焦化学工业污染物排放标准》(GB16171-2012)中的要求,且RO浓水中有机物种类可减少约62%。 The researchers conducted experimental studies on the removal efficiencies of COD and TN in biochemical effluent of concentrated coking wastewater. The investigation on the effect of different factors was carried out by applying the processes including O3/H2O2 and adsorption of activated carbon. The results showed that COD and TN were lower than 40 and 10 mg/L respectively when adding 0.6 mL H2O2 with a reaction time of 25 minutes as well as keeping the pH=8~9 and adding 20 mg/L activated carbon. In addition, the amount of organics in RO concentrated wastewater could be reduced by about 62 %.
