摘要
根据焦化废水的特点及水质情况,对原有焦化废水系统进行了改造。采用内置生物填料的改良生物法,总氮脱除效率由原来的58%提高到95%,可以控制外排水总氮含量在20 mg/L以下,实现焦化废水达标排放。
A modification has been done for the existing coking waste water system according to the effluent behaviors and water quality.A new bio-process with built-in type packings can increase the efficiency of total nitrogen removal from 58% to 95% and can control the total nitrogen content lower than 20 mg/L at the plant outlet so as to meet the requirement of waste water discharge.
