Ti/RuO2-ZrO2电极电解处理焦化废水生化出水
Technology of Water Treatment(2020)
Abstract
采用热分解法制备了Ti/RuO2-ZrO2钛基金属氧化物涂层电极,利用扫描电镜、X射线衍射仪等方法对电极的形貌结构和金属涂层物相进行了表征,并以该涂层电极为阳极,经预处理的钛板作为阴极构建了电化学催化反应发生体系以处理焦化废水生化出水.结果 表明,在电流密度10 mA/cm2、pH为7、电解时间60 min、反应温度25℃的优化条件下,焦化废水生化出水经电解处理后COD去除率可达96.2%,TOC去除率达87.0%,UV254大幅下降,原水中杂环类和环烷烃类有机物可降解为单环及简单链状烃类.
