摘要： 改善污泥脱水性能对大幅减少生化剩余污泥体积意义重大。采用湿式氧化方法对生化剩余污泥进行消解，可将污泥的主要污染物高分子挥发性悬浮物降解，使其转变为水溶性蛋白质、糖、有机酸及氨氮等小分子有机物，使污泥脱水性能得到显著改善而容易脱水。
关键词: 污水生化, 剩余污泥, 湿式氧化, 体积减量
Abstract: The improvement of sludge dewater ability is essential to the volume reduction of waste activated sludge (WAS). The wet air oxidation process is used for WAS degradation. It is found that the volatile suspended sludge is decomposed into small molecular organic compounds, such as soluble protein, carbohydrate, short-chain fatty acids and ammonia by wet air oxidation, which improves the sludge dewater ability significantly.
Key words: waste water bio-treatment, excess sludge, wet air oxidation, volume reduction
