| 摘 要： | 厌氧消化是常用的污泥稳定化处理方法，但污泥经厌氧消化处理后脱水性能恶化。分别用无机-有机复合调理剂和物理-化学复合调理剂对厌氧消化污泥进行调理，考察不同调理方法对污泥脱水性能的影响。结果表明，聚合氯化铝（PAC）、聚合硫酸铁（PFS）和阳离子聚丙烯酰胺（PAM）对厌氧消化污泥的调理效果有限，最优条件下污泥比阻（SRF）分别下降了66.3%、89.2%和67.1%；PAC-PAM复合调理和PFS-PAM复合调理对厌氧消化污泥的调理效果较单种调理剂好，最优条件下SRF分别下降了98.2%和97.6%；稻壳、木屑和草木灰与PAM复合调理对厌氧消化污泥的调理效果较单种调理剂好，最优条件下SRF分别下降了97.3%、97.3%和97.7%。

| Abstract: | Anaerobic digestion is a common method for sludge stabilization.However, the dewaterability of sludge deteriorates after anaerobic digestion.This study investigated the effects of inorganic-organic and physical-chemical conditioners on the dewaterability of anaerobic digested sludge.The results indicate that the specific resistance to filtration (SRF) of polymeric aluminum chloride (PAC), polymeric ferric sulfate (PFS), or cationic polyacrylamide (PAM) conditioners (individually) on the dewaterability of anaerobic digested sludge were 66.3%, 89.2%, and 66.3%, respectively, after optimization, which was not significant.The co-conditioning effects of PAC-PAM and PFS-PAM were better than that of a single conditioner.The SRF reduction rates of anaerobic digested sludge conditioned by PAC-PAM and PFS-PAM were 98.2% and 97.6%, respectively, after optimization.Furthermore, the co-conditioning effects of rice husks, sawdust, and plant ash combined with PAM were better than that of a single conditioner.The SRF reduction rates could reach 97.3%, 97.3%, and 97.7%, respectively, in optimal conditions. |
