| 摘 要： | 采用γ-射线辐照法对城市剩余活性污泥进行处理,探讨了γ-射线辐照对污泥理化性质的影响.试验结果表明,在吸收剂量为0~15 k Gy范围内,污泥的p H和ORP没有显著变化,不会对污泥后续处理处置带来不利影响.污泥碱度有所提高,沉降—浓缩性和离心脱水性得到明显改善,TS、VS、TSS和VSS均有所下降,表明γ-射线可以破解污泥细胞组分,有利于污泥减量.

| Abstract: | Gamma-ray irradiation effects on residual sewage sludge were studied from the physicochemical characteristics.Results showed that,at irradiation dose from 0 to 15 kGy,pH and ORP remained constant.Alkalinity was increased,sedimentation-thickening property and dewatering property were clearly improved,and TS,VS,TSS,VSS were decreased which could break sludge cellular components,leading to sludge reduction. |

| Keywords: | gamma-ray irradiation sludge treatment sludge reduction |
