摘　　要：潍坊市污水处理厂污泥无害化处置工程是一个突破传统、定制化设计的污泥堆肥项目,600 t/d处理能力分为两个处理系列:系列1为400 t/d(含水率80%)进入板框压滤脱水,出泥含水率≤60%,之后进入好氧发酵工艺;系列2为200 t/d(含水率80%)直接进入好氧发酵工艺。介绍了工艺流程、工艺设计(物料衡算、单体工艺参数、主要设备等)。项目特点:采用定制化设计;深度机械脱水与堆肥系统相结合;完善的资源化加工系统与畅通的资源化处置出路。运行效果:系列1运行成本可控性较好,升温慢,产物满足土壤改良要求;系列2运行成本可控性稍差,升温腐熟快,产物满足有机肥原料要求。The sludge harmless disposal project of Weifang sewage treatment plant is a breakthrough in tradition and customized sludge composting project.The 600 t/d treatment capacity is divided into two treatment series:①400 t/d sludge with water content of 80%goes into the plate and frame pressure filtration dehydration to obtain the sludge with water content below 60%,and then goes into the aerobic fermentation process;②200 t/d sludge with water content of 80%goes directly into the aerobic fermentation process.This paper introduced the process flow and process design(material balance,parameters of each process,main equipments,etc.).The project has the characteristics of customized design,combination of deep mechanical dehydration with composting system,perfect resource processing system and smooth resource disposal outlet.The controllability of operation cost of series①is good,the temperature rises slowly,and the products meet the requirements of soil improvement.The controllability of operation cost of series②is slightly poor,the temperature rises quickly and the sludge decays fast,and the products meet the requirements of the raw materials for organic fertilizer.
