固定床吸附树脂法深度处理焦化废水

摘要

The coking waste water after biochemical coagulation is pretreated by tube settling pond and 0. 4~1. 2mm shallow sand filter, and then deeply treated by fixed-bed resin absorption. The wa-ter after treatment meets the requirement of recycling. The concentrated liquid generated by the regeneration of resin absorption bed is sent to the biochemical unit after Fenton oxidation.%生化混凝后焦化废水用斜管沉淀池和0.4~1.2mm浅层砂滤预处理后，经固定床树脂吸附深度处理，出水达到回收利用要求；树脂吸附床再生产生的浓缩液用Fenton法氧化后送到生化装置。
