摘　　要：研究选取两家长江水源水厂的脱水污泥作为跟踪对象,分析其资源环境属性,为明确其处理处置风险及可行性提供数据支撑。结果表明:两家水厂脱水污泥夏秋季温度高、p H低,冬春季温度低、pH高。通过相关性分析可知,其中有机物含量与进厂原水有机物含量相关性不高,但与含水率相关性较高,可通过测定含水率作为判断其有机物含量高低的依据之一。脱水污泥污染指标及其堆放区域附近大气污染物排放指标基本全面优于各项标准中规定的限值,可应用于多种类型的资源化利用场景。其粒径分布接近黏土、亚黏土或粉砂类,无机组分以SiO_(2),Al_(2)O_(3)和Fe_(2)O_(3)为主,可作为一种类黏土原料,开展广泛的资源化处置。This study selected sludge from two Yangtze River WTPs as tracking objects to analyze their resource and environmental properties,to provide data support for clarifying their treatment and disposal risks and feasibility.The results showed that the sludge from two WTPs had high temperatures and low pH in summer and autumn,and low temperatures and high pH in winter and spring.Through correlation analysis,it could be concluded that the correlation between its organic matter content and the organic mater content of the incoming raw water was not high,but it was highly correlated with the organic content.Therefore,measuring the organic content could be used as one of the criteria to judge the level of organic content.The pollution indices of the sludge and the emission indices of atmospheric pollutants near its storage area were generally better than the limits specified in various standards,thus it could be applied to various types of resource utilization scenarios.Meantime,its particle size distribution is close to that of clay,loam,or silt,with inorganic components mainly composed of SiO_(2),Al_(2)O_(3),and Fe_(2)O_(3),which can be widely used as a type of clay raw material for resource disposal.
