摘要
分别对二氯吡啶、四氯吡啶废水以及2股废水的混合水样中COD Cr的去除研究,确立了二氯吡啶废水"三效蒸发"、四氯吡啶废水"铁碳微电解+Fenton氧化"的预处理工艺,后续采用"UASB-好氧-二沉"的废水生化处理工艺,最终使出水达标排放。
The removal of COD in dichloropyridine wastewater, tetrachloropyridine wastewater and the mixture of two wastewater were researched. Experimental results indicated that ＂triple effect evaporation＂ will be used in the pretreatment process of dichloropyridine wastewater, while ＂iron-carbon micro-electrolysis and Fenton oxidation＂ will be used in the pretreatment of tetrachloropyridine wastewater, and the following biochemical treatment process using ＂UASB＋ aerobic ＋ two sink＂ eventually made the water reach the discharge standard.
