    摘要
  • 摘要: 研究了水力空化-酸化调理作用于污泥脱水的机理。以污泥比阻（specific resistance to filtration，SRF）、污泥含水率和污泥毛细吸水时间（capillary sunction time，CST）作为主要的评价指标，测定污泥胞外聚合物（extracellular polymeric substances，EPS）中多糖、蛋白含量并进行了污泥酸化程度、污泥电子显微图像分析。结果表明：经水力空化-酸化调理污泥，污泥含水率和SRF分别从83.1%和5.12×1011 m/kg下降到69.8%和2.41×1011 m/kg，CST由50 s下降至20.8 s，各EPS组分含量下降明显，酸化作用通过影响污泥的溶解型胞外聚合物（S-EPS）和松散结合型胞外聚合物（LB-EPS）中的多糖及蛋白含量改变污泥的脱水性，pH=3时污泥脱水效果最好。综上所述，水力空化-酸化调理能大大增强污泥的脱水性能，在实际工程中具有很大的应用价值。
    Abstract: The mechanism of hydrodynamic cavitation-acidification conditioning on sludge dewatering was studied. Specific resistance to filtration (SRF), sludge moisture content and capillary sunction time (CST) were the major indicators to evaluate the sludge dewatering performance. The content of polysaccharides and protein in extracellular polymeric substances (EPS) were determined, and sludge acidification extent and sludge electron microscopic image was analyzed at the same time. The results showed that the moisture content and SRF of the sludge decreased from 83.1% and 5.12×1011 m/kg, to 69.8% and 2.41×1011 m/kg, respectively, and the CST time decreased from 50 s to 20.8 s. The content of each EPS component decreased significantly. The acidification changed the dewatering property of the sludge by affecting the polysaccharide and protein content in the S-EPS and LB-EPS of the sludge. The sludge had the best dewatering effect at pH=3. In summary, hydrodynamic cavitation-acidification conditioning could greatly enhance the dewatering performance of sludge, and had great application value in practical engineering.
