三相流化床电Fenton法预处理硝基苯废水试验研究

Experimental Study of Three-phase Fluidized Bed Electricity Fenton Reaction Pretreatment of Nitrobenzene Wastewater

采用铁碳微电解固定床、铁碳微电解流化床、电絮凝、电氧化等不同的组合方法,处理难降解的硝基苯类废水,找出最佳的组合工艺,即三相流化床组合电絮凝,配合后续间接电芬顿,能将难降解废水COD435ppm处理到COD小于90ppm,色度小于2倍,很有推广价值。

This paper adopted different combinations of methods, including iron carbon micro-electrolysis fixed bed, iron carbon micro-electrolysis fluidized bed, electricity flocculation and electricity oxidation to processing hard-degradation nitrobenzene wastewater. The best combination process, namely three-phase fluidized bed combination electric flocculation with subsequent indirect electricity, will degrade wastewater COD from 435ppm to less than 90ppm, chromaticity less than 2 times. This method has significant promotion value.
