| 中文摘要: |
| 污泥焚烧是具有良好发展前景的污泥减量化技术。依据 GB 5085.1-2007至 GB 5085.6-2007等相关规范，
对合肥东方热电有限公司燃煤锅炉掺烧污泥飞灰和炉渣属性进行了分析和鉴别。鉴别结果表明，燃煤热电厂
锅炉掺烧城市生活污水处理厂污泥比例在不高于 6.7% 的情况下，飞灰和炉渣均不具备危险废物特性，可按照
一般工业固体废物进行综合利用。同时，焚烧飞灰和炉渣 pH较高，已接近《危险废物鉴别标准 腐蚀性鉴别》（GB
5085.1-2007）标准限值，故飞灰和炉渣综合利用时应选择对 pH 值要求较低的综合利用方式。 |

| Sludge burning is considered to be a kind of sludge reduction technology which has good prospects for development.
According to standards GB 5085.1-2007—GB 5085.6-2007， the characteristics of ash and cinder generated by coal-burned boilers
blended with sludge of Hefei Dongfang Thermal Power Plant are analyzed and identified. It is recognized that when the blended sludge
proportion is not higher than 6.7%， the fly ash and cinder from coal-burned boilers blended with sewage sludge does not have the
characteristics of hazardous solid waste and can be utilized as general solid waste. However the pH of fly ash and cinder is high and
nearly close to the standard limit“Identification standards for hazardous wastes — Identification for corrosivity”（GB 5085.1-2007）.
The utilization way of ash and cinder with lower requirements for pH should be selected. |
