摘要:
以福州某工业区煤焦油处理废水为例,采用单因素实验和正交实验方法,以 CODCr 去除率为考查因子,探讨微电解 -Fenton 氧化工艺对高浓度难降解有机废水的处理效果,确定主要影响因素及最佳条件,为工程应用提供参考。实验结果表明:当水样的 CODCr 59600 mg/L BOD5 7748 mg/L 时,影响微电解 -Fenton 氧化组合工艺 的主要因素依次为 H2O2 投加量、 Fe/C 质量比、水样 pH 值,并且在 Fe/C 质量比为 1:1 H2O2 投加量为 4 mL/L pH 值为 3 左右时, CODCr 总去除率最佳,达到 80.0% ,可生化指数 B/C 从处理前的 0.13 提高到 0.32 ,微电解 -Fenton 氧化工艺可有效的处理高浓度难降解有机废水,提高可生化处理程度。
Abstract:
The pretreatment of wastewater of some industrial park in Fuzhou city with coal-tar was conducted by micro-electrolysis combined with Fenton oxidation process. Through the single factor experiments and orthogonal test, the influencing factors were investigated and the optimal conditions were determined. The results show that the main influential factors are in the order of the dosage of H2O2, iron-carbon ratio and pH value when the wastewater CODCr is 59600 mg/LBOD5 is 7748 mg/L. When the reaction time for the micro-electrolysis is 1 h, the pH value is about 3.0, the reaction time for the Fenton oxidation is 1 h and the dosage of H2O2(30%) is 4 mL/L , the removal rate of CODCr reaches about 80.0 % while the B/C increases from 0.13 to 0.32. The results indicate that the treatment may contribute to biological treatments
