毕业设计（论文）白色垃圾治理途径的探讨摘要“白色污染”主要指白色的发泡塑料饭盒，各种塑料袋，农用地膜等给环境造成的污染。“白色污染”物的主要成分为：聚乙烯(PE)、聚氯乙烯(PV)、聚丙烯(PP)、聚苯乙烯树脂(PS)。这些废弃塑料制品是由难降解的高分子材料聚合而成,进入环境后长期不分解、不腐烂,对城乡生态环境造成很大危害，破坏市容环境，危害人体健康，破坏生态环境等。治理白色污染的有效途径之一就是将白色垃圾作为一种宝贵的资源回收利用,这是治理白色污染的大趋势。同时各级政府要加强对城市塑料垃圾清收管理工作的组织领导，要建立建全废弃塑料包装制品的回收机制，建立健全塑料垃圾处置费征收制度。关键词：“白色污染”，组成成分，原因，危害，治理途径，对策I毕业设计（论文）WHITEGARBAGEMANAGEPATHOFSTUDYABSTRACT"Whitepollution"mainlyreferstothewhiteplasticfoamlunchboxes,allkindsofplasticbags,plasticfilm,suchasagriculturalpollutiontotheenvironment."Whitepollution"werethemaincomponentsare:polyethylene(PE),polyvinylchloride(PV),polypropylene(PP),polystyrene(PS).Thesediscardedplasticproductsarerefractoryaggregatefromthepolymermaterialsintotheenvironmentdonotbreakdownlong-term,non-perishable,andtheecologicalenvironmentinurbanandruralareascausedgreatharm,destructionofenvironmentandendangerhumanhealth,damagetheecologicalenvironment.Whitepollutioncontroloneoftheeffectivewaysistowhiteasagarbagerecyclingofvaluableresources,whichisgovernanceofthegeneraltrendofwhitepollution.Atthesametime,governmentsatalllevelsshouldstrengthentheplasticrubbishremovalinthecityclosemanagementoftheorganizationandleadership,itisnecessarytoestablishabuilding-wideplasticpackagingwasterecoverymechanism,andestablishandimprovethedisposalofplasticgarbagefeecollectionsystem.KEYWORDS:"Whitepollution",status,composition,environmentalhazards,governancemeansII毕业设计（论文）目录前言...............................................................................................1第1章“白色污染”的概念.................................2第2章“白色污染”的现状....................................3第3章“白色污染”的组成成分.......................43.1聚乙烯...............................................................................43.2聚丙烯...............................................................................43.3聚氯乙烯........................................................................53.4聚苯乙烯........................................................................5第4章“白色污染”的影响.......................................64.1破坏市容环境...........................................................64.2危害人体健康...........................................................64.3破坏生态环境...........................................................6第5章治理“白色污染”的途径.......................85.1要加强对塑料垃圾的清收管理工作85.2要建立建全废弃塑料包装制品的回收机制............................................................................................95.3建立健全塑料垃圾处置费征收制度95.3.1向生产塑料包装制品和一次性快餐盒的企业征收处置费.................................95.3.2向销售和使用塑料包装制品及一次性快餐盒的单位、业户收取处置费..................................................................................................105.3.3向城市居民征收垃圾处置费.......105.3.4向使用农膜、大棚膜的农民征收垃圾处置费..............................................................10结论...................................................
