摘　　要：在２Ｌ高压釜中用氧气进行了湿式氧化处理城市污水厂活性污泥的研究，并对处理后的污泥上清液中氮、磷、重金属变化规律和剩余污泥中挥发分、热量、有机物含量的变化规律进行了分析。试验结果表明，处理后污泥的沉降脱水性能极佳，对污泥中固体的去除结果也较好。Wet air oxidation process for treating waste activated sludge from a municipal wastewater treatment plant was studied experimentally in a 2 liter autoclave with oxygen as oxidang. The variations of the concentration of nitrogen, phosphorus and heavy metals in supernatang of the treated sludge and volatile consituents, heat capacity, organic content in excess sludge were analyzed. The test results showed that the characteristics of sludge settling and dewatering were excellent and removal of solid contents from the sludge was good after treatment.
