磁助混凝沉淀-fenton氧化法处理酸性红4-BE染料废水的实验研究

Study on Treatment of Acidic Red 4-BE Dye Wastewater by Magnetic-assistant Coagulation-Fenton method

中文摘要英文摘要

本文首先采用混凝沉淀-fenton氧化法对酸性红4-BE染料废水进行处理,讨论了影响CODcr去除率的各种因素,另在外加磁场条件下,协助fenton氧化对混凝沉淀后的废水进行了进一步处理。结果表明,对初始浓度为400mg/L、CODcr为346 mg/L、色度为2200倍的4-BE染料废水,CODcr去除率达到95%,脱色率达到99.3%;外加磁场作用时,使fenton氧化处理废水的时间缩短,提高了反应效率。

The Coagulation-Fenton was used in treating acidic red 4-BE dye wastewater in first and all kinds of influential factors of removal CODcr were discussed in this article, by importing magnetization assisted Fenton to optimize wastewater more after coagulation. As is indicated in the results of the experiment by using Coagulation-Fenton, when the initial concentration of the dye was 400mg/L,CODcr was 346mg/L and chroma was 2800 times, the total removed rate of CODcr reached 95% and colority reached 99.3%; besides, the time to treat wastewater by using fenton in magnetization was decreased, which improved the efficiency of reaction.
