摘要

摘要: 自2004年国内首座污泥焚烧工程在上海石洞口污水处理厂建成投运以来，污泥独立焚烧方式在国内重点城市逐步推广应用。由于城镇污水处理设施规划建设相对分散，且污泥性质多变，而污泥独立焚烧设施规划建设相对集中，不同性质污泥对于干化焚烧设施的规划选址、立项决策、工程设计和经济稳定运行带来较大影响。以青岛市某污泥焚烧厂规划和工程设计为例，目前市区主要污水厂的污泥性质，由于污水性质差异及处理方式不同存在较大差异。基于各污水厂污泥含水率、污泥有机质含量等数据开展理论研究，构建了能量平衡计算模型并以此为基础形成了一套污泥分配方案，同时建立了一种针对不同性质污泥的简化成本计算方法，为污泥干化焚烧项目多种性质污泥的差异性定价和合理分配提供参考思路。同时结合污泥含水率差异，针对普通脱水和深度脱水2种不同接收污泥性质，在“污水厂+污泥焚烧”的维度，针对污泥自始端至末端的全过程成本和全过程碳排放进行对比，从而为城市污泥处理处置的整体规划和工艺优化提供支撑。

Abstract: Since China's first domestic sludge incineration project was completed and put into operation at the Shidongkou Wastewater Treatment Plant in Shanghai in 2004， this technology has been gradually adopted and promoted in key economically developed cities in China. However， as urban wastewater treatment facilities are often planned and constructed in a decentralized manner and employ diverse process technologies， the sludge characterization is changeable. In contrast， the planning and construction of sludge mono-incineration facilities are relatively concentrated， sludges with different properties have brought great impacts on the planning and site selection， project decision-making， engineering design， and economic stable operation of drying and incineration facilities. Taking the planning and engineering design of a sludge incineration plant in Qingdao as an example， the properties of sludge from major wastewater treatment plants in the urban area currently vary significantly due to differences in wastewater characteristics and treatment processes. Based on the data of sludge moisture content， organic matter content and other key indicators from each wastewater treatment plant， theoretical research was carried out to construct an energy balance calculation model. Based on this model， a set of sludge distribution plans was formulated， and a simplified cost calculation method for sludge with different properties was developed， which provides a reference for the differentiated pricing and rational allocation of sludge with multiple properties in sludge drying and incineration projects. Meanwhile， combined with the differences in sludge moisture content， and aiming at the two types of received sludge properties （conventional dewatering and deep dewatering）， a comparative analysis was carried out on the whole-process costs and carbon emissions from the sludge's origin to its final disposal from the perspective of "wastewater treatment plant + sludge incineration"， to provide support for the overall planning and process optimization of urban sludge treatment and disposal.
