Abstract:

Fe⁰-H₂O₂oxidation is used to treat indust rial wastewater. Phenol(5000mg/L)and cresol(4000mg/L) are also used in the ex periments. The results show that after 330 minutes,the DOC conversion rate is 80% and yields less mire after neut ralization by using Fe⁰-H₂O₂ oxidation. But under the same ex perimental conditions, when traditional Fenton oxidation is used,the DOC conversion rate is only 60%. And if the conversion rate get shigher,there w ill be lots of mire yielded. Therefore,Fe⁰ -H₂O₂ oxidation is considered to be better than Fenton oxidation.

Key words: Fe⁰-H_{2O² oxidation,} conversion rate, organic waste

摘要：

提出了用于工业废水处理的Fe⁰-H₂O₂ 氧化法,并用高浓度苯酚 (5000mg/L)和甲酚(4000mg/L)进行实验,结果表明Fe⁰-H₂O₂氧化法在 330min后,DOC转化率达80%,中和后污泥产生量少,而传统Fenton氧化法,同等实验条件下,DOC转化率仅为60%,而且后者再提高转化率,中和时伴随大量污泥产生,因此认为Fe⁰-H₂O₂氧化法优于Fenton氧化法。
