摘要
采用铁板做电极,对糠醛废水进行了电解预处理.通过电解过程中由Fenton反应生成的羟基自由基的强氧化作用以及电解过程中生成的Fe(OH)3的絮凝作用来降解糠醛废水中的有机物.试验结果表明:经过电解预处理后,CODCr去除率为21.1%,BOD5/CODCr值升高了39.4%,为后续生化处理创造了良好的条件.
The furfural wastewater was treated by electrolytic previous treatment with iron electrode. The organic pollutants were decomposed by oxidative effect of hydroxyl radical and flocculating effect of Fe（OH）3. The result of experiment shows that： the value of CODCr reduced by 21% and the value of BOD5/CODCr increased by 36% after the electrolytic previous treatment which create a well condition for latter biological process.
