摘　　要：对超临界水氧化技术处理焦化废水进行了研究,主要从高温热解和超临界水氧化技术(SCWO)对CODcr、NH3-N的脱除率方面对超临界水氧化技术处理焦化废水进行了研究。研究结果表明:高温热解对CODcr有一定的去除率,对氨氮的去除率却出现相反的情况,出水氨氮浓度比进水氨氮浓度高。而超临界水氧化技术对CODcr、NH3-N的去除均起到一定的作用。This paper studies the treatment of coking wastewater by using the supercritical water oxidation technology mainly from the removal rate of CODcr and NH3-N with the high temperature pyrolysis and SCWO.The study results indicate that the high temperature pyrolysis has a certain effect on the removal rate of CODcr,but the opposite occurs on the removal rate of NH3-N because the concentration of NH4＋-N in effluent in the effluent is higher than that in the influent.However,SCWO plays a certain role on the removal of CODcr and NH3-N.
