摘　　要：超临界水氧化中试反应器(2.2 L+1.7 L)对制药回收溶媒后的残釜液进行处理,考察了反应温度、时间、压力及其氧气浓度对废水COD去除率的影响。结果表明,在温度为525℃,压力为24 MPa,氧化反应时间为90 s时,其COD去除率达到99.86%,处理后的排水能够达到国家规定的排放标准。对超临界水氧化反应过程的反应机理及放热现象进行了探讨。The experimental to treat cauldron bottom residue of antibiotic was researched by using 2.2 L ＋ 1.7 L supercfitieM water oxidation pilot-plant-soMe reactors. The effect of reaction temperature, reaction press,reaction time,and different oxygen concentration was analyzed. The result showed that when the reaetlon temperature is 525 ℃, the pressure is 24 MPa, the reaction time is 90 s, the steps stirring removal rate of COD can reach 99.86%. Effluent water quality ean meet the national wastewater-discharging standard. The reaction mechanism and phenomena of reaction heat in SCWO were discussed.
