2021年12月,生态环境等18部门联合印发关于《“无废城市”建设工作方案》和《“无废城市”建设指标体系(2021年版),提出推动100个左右地级及以上城市开展“无废城市”建设,到2025年,城市固体废物产生强度稳步下降,综合利用水平和比例大幅提升,区域处置设施缺口基本补齐,减污降碳协同增效作用明显,基本实现固体废物管理信息“一张网”,“无废”理念得到广泛认同,固体废物治理体系和治理能力得到明显提升。
整套处理工艺流程由智能化控制系统发出信号:通过多级破碎、物料干化、密度筛分、智能分拣、 磁选回收、涡电流分选、压缩成型等工序,可根据下游客户应用加工成絮状或块状燃料,针对生活垃圾处理特别配备负压除臭除尘设施和污水处理设施,有效化解垃圾处理产生的邻避效应。
In December 2021, 18 departments including the ecological environment jointly issued the Work Plan for the Construction of "Waste Free City" and the "Waste Free City" Construction Index System (2021), proposing to promote the development of "Waste Free City" in about 100 prefecture-level cities and above Construction. By 2025, the generation intensity of urban solid waste will be steadily reduced, the level and proportion of comprehensive utilization will be significantly improved, the gap of regional disposal facilities will be basically filled, the synergy of pollution reduction and carbon reduction will be obvious, the "one network" of solid waste management information will be basically realized, the concept of "no waste" will be widely recognized, and the solid waste treatment system and capacity will be significantly improved.
The whole set of treatment process flow is signaled by the intelligent control system: through multi-stage crushing, material drying, density screening, intelligent sorting, magnetic separation recovery, eddy current separation, compression molding and other processes, it can be processed into flocculent or blocky fuel according to the application of downstream customers. For the treatment of living waste, it is specially equipped with negative pressure deodorization and dust removal facilities and sewage treatment facilities to effectively resolve the proximity effect generated by waste treatment.
