Fenton试剂处理青霉素废水实验研究

Study on Treatment of Benzylpenicillin Wastewater with Fenton Reagent

以青霉素废水为研究对象 ,初步探讨了 Fenton试剂处理有毒有机废水时各影响因素的作用机制 ,通过实验确定了 Fenton试剂氧化降解青霉素废水的适宜操作条件为 :CODCr为 30 0 0 mg/L左右的青霉素废水 ,p H为 6.0、H2 O2 (30 % )投加量为 0 .6% (体积分数 )、Fe SO4 · 7H2 O投加量为 0 .2 % (质量分数 )、反应时间为 lh,此条件下废水 CODcr的去除率可达 70 % ,而且该方法设备简单 ,易于下一步实现工业放大 ,是一种有较好开发前景的处理青霉素废水工艺。

The mechanisms of affecting factors in treating toxic organic wastewater such as benzylpenicllin wastewater with Fenton reagent were investigated systematically.The optimal operating conditions determined by experiments were as following:for benzylpenicllin wastewater(COD Cr=3000mg/L),pH was 6.0、30%H 2O 2 was 0.6%(volume fraction)、 FeSO 4·7H 2O was 0.2%(mass fraction)、reaction time was 1h.Under these conditions,the COD Cr removals could reach 70%.It was a development foreground process for its simple process flow.
