  • 摘要: 采用内循环微电解技术对某焦化厂生化混凝出水进行深度处理，以达到国家提标标准。通过单因素实验考察了pH、反应时间、曝气量和铁炭比对处理效果的影响，在此基础上，筛选出影响COD去除率的主控因子，并采用Box-Behnken响应曲面法对内循环微电解处理焦化污水的工艺条件进行优化，同时考察了各因素间的交互作用对COD去除率的影响。确定的最优运行参数为：pH 2.3、曝气量0.13 m3·h-1和铁炭比1:1。最优运行参数下的验证实验结果显示COD去除率和色度去除率分别达到67.77%和93.75%，当进水COD低于180 mg·L-1时，出水COD能够达到《炼焦化学工业污染物排放标准》（GB 16171-2012）直排标准。
    Abstract: In order to meet the new national standard, the internal cycling micro-electrolysis technology is adopted for treating the effluent from the flocculation sedimentation tank of coking plant. The effects of pH value, reaction time, aeration rate and iron-carbon ratio on the treatment performance were investigated by single-factor experiment. Based on the results obtained from the single-factor experiment, three main factors in terms of influencing COD removal rate were selected. Box-Behnken response surface method was used for optimizing the process conditions of the proposed treatment method, as well as, the interaction between any two factors was carried out. The optimal operating conditions were obtained, i.e., pH is 2.3, the aeration rate is 0.13 m3·h-1 and the iron/carbon ratio is 1:1. The COD removal efficiency and chroma removal rate under the optimal operating conditions were 67.77% and 93.75%, respectively. Therefore, when the inlet COD is lower than 180 mg·L-1, the effluent COD can meet the requirements of the first class of Coking Chemical Industry Pollutant Discharge Standard (GB16171-2012).
