  • 摘要: 通过投加零价铁和增加微电场提高水解酸化的效果，改善混合工业废水的可生化性。实验在4个反应器中同步进行：微电场-零价铁厌氧反应器（R1）、微电场厌氧反应器（R2）、零价铁厌氧反应器（R3）及普通厌氧反应器（R4）。结果表明，微电场-零价铁对水解酸化具有明显的促进作用，在水力停留时间（HRT）为81 h时，TOC去除率达70%，BOD5/COD由0.15增至0.41，废水的可生化性显著提高。
    Abstract: The biodegradability of industrial wastewater mixture was improved with the addition of zero-valent iron(ZVI) and micro-electric field which enhanced the effect of hydrolytic acidification.The experiments were carried out simultaneously in four reactors:micro-electric field-zero-valent iron(ZVI) anaerobic reactor (R1),micro-electric field anaerobic reactor (R2),zero-valent iron anaerobic reactor (R3) and regular anaerobic reactor (R4).It is demonstrated that micro-electric field-zero-valent iron facilitated hydrolytic acidification evidently,with a TOC removal rate of 70% at hydraulic retention time (HRT) of 81 h and BOD5/COD from 0.15 to 0.41.As a result,the biodegradability of wastewater was significantly improved.
