  • 摘要: 采用Fenton法处理某电镀厂强碱性有机废水。考察了pH和Fenton氧化对废水特性的影响，优化了处理参数，研究了Fenton氧化对废水可生化性的影响。结果表明：Fenton氧化前，调节pH可提高有机物去除效果，一定程度上去除重金属；Fenton法能够有效处理电镀有机废水，并充分提高废水可生化性，最高COD去除率可达75%；在反应时间为30 min、H2O2投加量为68 mg·L-1、Fe2+投加量为111 mg·L-1条件下，废水COD去除率为22%，B/C为0.28，适宜后续接入生化工艺以进一步提高废水处理效果，可降低成本并提高处理效率，为电镀企业处理强碱性有机废水提供参考。
    Abstract: Fenton process was used to treat strongly alkaline organic wastewater from an electroplating factory. Effects of pH and Fenton oxidation on wastewater characteristics were investigated, the optimal parameters were explored, and the effect of Fenton treatment on biodegradability of this type of wastewater was studied. The results showed that adjusting pH during Fenton oxidation could improve removal of organics and remove heavy meatals to some extent. Fenton process was an effective treatment of the electroplating organic wastewater and effectively improved the biodegradability of the wastewater, the highest removal efficiency of COD was up to 75%. Under the optimal conditions (oxidation time 30 min, H2O2 dosage 68 mg·L-1 and Fe2+ dosage 111 mg·L-1), the COD removal efficiency and B/C of wastewater were 22% and 0.28, respectively. The so treated effluent was suitable for subsequent biological treatment and such a combination was had both economic efficiency and treatment efficiency. The results can provide reference for the practice in treating strongly alkaline organic wastewater in electroplating enterprises.
