摘　　要：采用超临界水氧化反应中试装置对石家庄市某垃圾填埋场的高浓度垃圾渗滤液进行处理。试验结果表明:在反应温度为400℃、反应压力为26MPa、氧化反应时间为250s时,对COD的去除率达到99.61%。处理出水的各项指标均达到国家排放标准。同时对垃圾渗滤液超临界水氧化过程中排放的气体成分进行了分析,发现含有NOx污染气体。The pilot-scale supercritical water oxidation （SCWO） reactor was used to treat the high-concentration landfill leachate from a landfill site in Shijiazhuang City. The results show that when the reaction temperature is 400℃, the reaction pressure is 26 MPa and the oxidation time is 250 seconds, the COD removal rate can reach 99.61%. The effluent quality can meet the national wastewater discharge standard. The gas components emitted during SCWO were analyzed, and the nitrogen oxides were found.
