  • 摘要: 活性污泥水解对提高污泥的稳定性、缩短厌氧消化时间和增大甲烷产率具有重要意义。研究了脉冲弧光放电等离子体（PADP）水解活性污泥方法，考察水解效果、影响因素和水解后的污泥性状。结果表明：随着峰值电压、频率和电导率的增加，污泥上清液营养物质含量呈增长趋势，溶胞率（R）升高；随着放电时间的增加，R增加，氨氮物质（NH4+-N）先增加后降低，可证明NH4+-N降解率逐渐上升且最终高于其释放率；污泥在14 kV、25 Hz、1 600 μS·cm-1条件下放电150 min，R增加到51.3%，NH4+-N、蛋白质和多糖等有机物大量释放；经过PADP处理，污泥沉降性降低，絮凝体结构改变，含固量和颗粒尺寸降低，污泥生物大量死亡，水解污泥生物由光滑、完整的表面结构变得粗糙、破裂，细胞壁（膜）受损明显，污泥发生水解。
    Abstract: It is very significance of activated sludge hydrolysis for improving sludge stability, shortening the anaerobic digestion time and increasing methane yield. Pulsed arc discharge plasma (PADP) was utilized to investigate the hydrolysis effect, influence factor and character of hydrolyzed sludge. The results showed that higher peak voltage, frequency and conductivity enhanced sludge hydrolysis. With the increase of discharge time, lysis rate (R) increased, concentration of ammonia nitrogen (NH4+-N) increased first and then decreased, which could demonstrate that the degradation rate of NH4+-N increased gradually and it was higher than the release rate at last. R could reach approximately 51.3% under 14 kV peak voltage, 25 Hz frequency and 1 600 μS·cm-1 conductivity with 150 min treatment time. In addition, NH4+-N, protein, polysaccharide and other organic matters of sludge could release extensively. After PADP treatment, the settleability of sludge reduced, the structure of flocs changed, the content of solid and the particle size decreased, sludge biological component died in large numbers, the complete and smooth surface structure of organisms became rough and rupture, respectively. The cell wall (membrane) was damaged significantly, activated sludge was finally hydrolyzed.
