1、.某城市生活垃圾综合分选处理系统设计固体废弃物处理通常是指通过物理、化学、生物、物化及生化方法把固体废物转化为适于运输、贮存、利用或处置的过程。垃圾分选，是垃圾处理技术的瓶颈，不管是焚烧、填埋处理工艺，还是综合处理工艺，很多失败案例都是因为垃圾分选不彻底，导致下工序无法处理而使整条生产线都不能正常运行。本文以设计处理量为350t/天的某城市生活垃圾分选处理系统为目标，确定了垃圾分选系统中的垃圾储料车间，行车与抓斗，磁选，破碎，筛分，风选等的工艺设计参数以及设计依据。同时确定了整个垃圾综合分选处理系统的工作流程、以及厂址的选择，厂区的布置。每天可产生金属9.03t/天、玻璃2.1

2、t/天、可以进行堆肥的190.05t/天、需要进行填埋的148.82t/天。具有很好的环境效益、经济效益和社会效益。关键词：城市生活垃圾，综合分选处理，工艺流程设计，效益分析THEDESIGNINGOFASORTINGSYSTEMOFTHEMUNICIPALSOLIDWASTE(MSW)DISPOSALEnglishAbstract:Solidwastetreatmentusuallyreferstopassthephysical,chemical,biological,chemicalandphysicalwaytosolidwastesasfortransportation
