摘　　要：在工业生态思想的指导下,以工业生产的废料和沙子为电催化电极,以自行组装的粒子群膨胀床为处理设备,对某焦化厂的焦化废水进行实验处理。研究表明,该曝气粒子群电极膨胀床能有效处理焦化废水,在反应时间为3.0 h,槽电压为9.0V,pH值为9.0,曝气量为80 L/min的条件下,可使进水COD由1 062 mg/L,降到497 mg/L。特别是焦化废水中难降解的含氮杂环化合物得到有效的降解和破解。Based on the theory of industrial ecology, the self-made expanded bed with waste material A and sand as electrocatalytic electrode was used to treat coking wastewater from a coking plant. The results show that the expanded bed with particle group electrode can effectively treat coking wastewater; under the conditions of pH=9.0, aeration rate 80 L/rain, retention time 3.0 h, working voltage 9.0 V, COD can be reduced from 1 062 mg/L to 497 mg/L, especially refractory heterocyclic compounds containing N can be degraded.
