【摘要】 随着我国污泥产量与日俱增，污泥处置过程中的碳排放量也随之增加，污泥的泥质特性是影响污泥处置和碳排放的重要因素。对近15 a来我国城镇污水厂脱水污泥的特性进行统计分析，总结污泥含水率、有机质、总氮、总磷、重金属含量的时空分布特征，并结合污泥处置工艺的碳排放计算方法，总结根据污泥特性选择合适的处置路径，为污泥的资源能源回收利用和低碳处置提供基础资料，推动实现我国污泥处置的碳减排目标。更多还原

【Abstract】 With the increase of sludge production of China, the carbon emissions during sludge treatment and disposal also increases, and the characteristics of sludge are an important factor affecting sludge disposal and carbon emissions. Statistical analysis was carried out on the characteristics of dewatered sludge from urban sewage plants in China in the past 15 years,and the temporal and spatial distribution characteristics of sludge moisture content, organic matter content, total nitrogen and total phosphorus content, and heavy metal content were summarized. Combined with the calculation methods of carbon emissions from sludge treatment and disposal processes, summarizes how to choose the appropriate treatment and disposal route according to the sludge characteristics. Providing basic information for the resource and energy recovery and utilization and low-carbon treatment and disposal routes of sludge, and promoting the realization of the carbon emission reduction target of sludge treatment in China.更多还原
