         for inner outer active waste waste plastics separation technology and 资源化 process simple introduction, 提出 三 types waste waste plastics 资源化 and separation technology optimization combined process. environmental protection enterprise comprehensive inner active waste features, combined 理组织生 active waste waste plastics 资源化, utilizing separation process and equipment combined methods most product and most large 资源化.

        随 社会经济飞 speed development, type 城市生 active waste output/production volume year increase large, its in waste plastics ratio/proportion 也呈逐 year upper rise trend. currently, 我国城市生 active waste in can recycling material ratio/proportion already ultra- 30%, main/primary is plastics, type, 橡胶, metal and and other, its in waste plastics ratio/proportion versus large.

         waste plastics for ring effect/influence can overlook, it difficult degradation property, can formed “ white 污染” issues. inner for active waste and 填埋场 waste plastics separation methods, more is through formed sleeve/set separation equipment will its classification, separation waste plastics according to market demand or requirements 寻求出路.

         separation methods main/primary utilizing waste plastics material property 质, through versus separation equipment will waste plastics from active waste or in separation 出. 资源化方面 can will waste plastics recycled, modified recycled, 焚烧, catalytic understanding, hydrogen understanding and other.

         currently inner still 未建立 versus for waste waste plastics separation technology and 资源化 utilizing 决策支持 technology system, in waste waste plastics separation or is will its 资源化 utilizing process upper 均缺乏科学 research 基础, about/regarding 两者间联系 research more add thin low. 因各国国情 different, Europe and Japan, USA and other 发达国家源头 classification as relatively is fine 致, make rear 预处理 and 资源化 utilizing system relatively 完善, 而我国此工 as 尚需数 year can to. USA in waste plastics recycling use according to method waste classification and 资源化 utilizing, Japan, USA related mono through R&D water force separation device for waste in plastics separation 选; USA certain 工学院研 made utilizing solvent agent selection property separation waste plastics technology. for/regarding outer waste and 资源化 utilizing technology, can 借鉴不 can formed sleeve/set 照搬.

         waste plastics 资源化 utilizing methods more, 但 别 waste plastics 资源化 process for raw materials and pure degree requirements relatively high, active waste through mono function 滚筒筛 and heavy force machine separation waste plastics 附 泥沙 and other material more, use pelletizing, from separation process upper equipment optimization combined, using/adopting combined equipment combined and optimization to rear 续资源化 process demand.

        由此 can 见, is 跟紧国家 environmental protection policy, meet/satisfy market demand, will waste plastics true positive to “无害化, decrease amount 化, 资源化” 目, combined 国情 生 active waste waste plastics separation technology and its 资源化 utilizing technology 间联系 research analysis in 必行.

        本文 through simple introduction active waste in waste plastics ratio, and other, and waste waste plastics separation process and 资源化 utilizing and other inner 容, comprehensive analysis 几者间 联系, 出 适应 China waste waste plastics separation and 资源化 utilizing sleeve/set process.

        一, waste in waste plastics ratio/proportion and 特征

         due to 填埋场 waste in has machine material will time degradation, inner 各区域填埋场 inner waste separation in 一定差别. 如钱千春 in 连续填埋14 year waste 填埋场 research waste plastics in waste separation in has relatively large ratio/proportion. 而方文君 for 湖北荆门老填埋场 research analysis 出, full 部填埋场 waste in, 腐殖土占 very large ratio/proportion, plastics 占10% left right, 腐殖土占75.7%, plastics 占10.1%, block 占8.7%, 木竹, material, 玻璃, metal, 纸张 占 ratio/proportion relatively small, separation is 2.2%, 1.4%, 0.6%, 0.3%, 0.1%, other amount less or difficult 以辨识 waste (包括螺 housing/shell, 橡胶, 骨头, 尿布, leather and other)占0.9%.

         plastics is types mono polymerization formed polymer/macromolecule material, separation is thermoplastic property and hot solid property. hot solid property plastics hot solid molding rear formed rear 呈不熔不 solvent property, aldehyde resin, ring oxygen resin, resin and other. property plastics can utilizing thermoplastic recycling utilizing. thermoplastic property plastics application 广泛, in temperature degree scope/range inner can add hot soft melt flow molding and cooling hard 化. thermoplastic property plastics active waste in main/primary Common has polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and other, can used for recycling utilizing.

        近五 year engineering and analysis 知: as 填埋场 waste separation material waste plastics, film plastics bag waste plastics ratio/proportion most large, can 达70% above. its in white plastics film (PE), color color film plastics (PE) separation is 24.5%, 39.7%. bottle plastics large more in front by 拾荒者 recycling, film plastics its utilizing value low, basic full by and other waste mixed combined 填埋.

        填埋场 and active waste in waste plastics 元素组 separation in 一定差异, main/primary is C, N, O, S, Cl, Si, Al and other, has research 证明, 填埋场 in waste plastics C content relatively new active waste in waste plastics low, 而N, O, Si, Al relatively high, S, Cl content relatively small.
