| 摘 要： | 对佛山6家印染厂污泥的基本性质和重金属污染进行了分析研究。结果表明:印染污泥有机质含量较高;对照农用污泥污染物限值和城镇污水处理污泥处置混合填埋用泥质标准,Cr、Ni、Cu、Zn不同程度超标,说明印染污泥既不能农用,也不能混合填埋。污泥浸出液中重金属浓度远低于危险废物浸出毒性限值和城镇污水处理厂污泥单独焚烧用泥质的污染物限值。污泥与煤掺混焚烧烟道气中二恶英浓度在0.0125～0.022 ngTEQ/Nm3,远低于GB 18485—2001《生活垃圾焚烧污染控制标准》限值和GB/T 24602—2009《城镇污水处理厂污泥处置单独焚烧用泥质》限值。 |

| Abstract: | Basic properties and heavy metal pollution of 6 samples from 6 different printing & dyeing plants in Foshan were studied.The results indicated that printing & dyeing sludges had very high organic matter levels.Cr、Ni、Cu and Zn exceeded standards variously compared with agricultural sludge pollutants limits and disposal of sludge from municipal wastewater treatment plant and that for co-landfilling,which explained that printing & dyeing sludge can not be used on agriculture or mixed landfill.Leaching tests indicated that the concentrations of heavy metals in leachate were far lower than hazardous waste leaching toxicity limits and disposal of sludge from municipal wastewater treatment plant and the sludge used in single incineration.Based on the printing & dyeing sludge and coal blending incineration process,the concentration of dioxins in flu gas is in the range of 0.0125 ～ 0.022 ngTEQ / m 3,which is far below pollutant limits of domestic refuse incinerator(GB 18485—2001) and the pollutant limits of sludge incinerator(GB / T 24602—2009). |
| Keywords: | printing & dyeing sludge heavy metals pollution leaching toxicity coal blending incineration dioxin |
