摘要/Abstract

摘要： 工业生产中未达标的废水直接排放是导致湖泊等受纳水体污染的一个重要原因。以焦化企业生化外排水为处理对象，采用微波－活性炭联用技术对废水中的NH³-N和COD进行同时去除研究。结果表明：随着活性炭用量的增加，COD去除率逐步增大，而NH³-N的去除率逐步下降；微波功率和辐射时间的增加有利于污染物的去除；采用微波-活性炭联用进行动态水处理试验时，废水中NH³-N和COD去除率分别可达85.3%和60.3%。此研究为工
业废水的治理提供了新的思路。

Abstract: Industrial waste which exceeds the national emission standard for the discharge of pollutants was a major cause of receiving waters pollution. The application of microwave(MW) and activated carbon (GAC) in the treatment of ammonia nitrogen (NH³-N) and Chemical Oxygen Demand(COD) in coking wastewater was explored in this study. It was shown that when GAC dosage increased, the removal rate of COD raised while the removal of NH³-N reduced. Removal of ammonia and COD in wastewater increased with the rise of MW power and radiation time. The removal rate of NH³-N and COD reached 85.3% and 60.3% respectively when the continuous flow microwave system was used to treat the coking wastewater. This study provided an alternative process for the treatment of coking wastewater.

Key words: microwave, ammonia nitrogen, COD, water treatment
