摘要:

介绍了焦化废水生化后尾水的深度处理工程实例。针对生化尾水的特点,选择了斜管沉淀、浅层介质过滤和树脂吸附的组合处理工艺,处理后尾水的色度、总氰化物、悬浮物的去除率分别达到89.7%、88.1%和69.6%,排水指标优于《炼焦化学工业污染物排放标准》(GB 16171—2012)中的要求,具有较好的应用前景。

Abstract:

This paper introduces some engineering examples of advanced treatment of coking wastewater after biochemical treatment.Considering the features of biochemical tail water,a new treatment process combining pipe chute sedimentation,primary filtration and resin absorption is proposed.The removal rate of chromaticity,total cyanide content and suspended solid of tail water after treatment are 89.7%,88.1% and 69.6% respectively.The indexes of discharged water are better than that specified in Emission Standard of Pollutants for Coking Chemical Industry GB 16171—1012.This method has good application prospect.
