2014届毕业(设计)论文题 目 塑料编织袋加工项目的污染分析与控制措施 -以XX市海星水泥包装实业有限公司为例 专业班级 学 号 学生姓名 学 院 指导教师 指导教师职称 塑料编织袋加工项目的污染分析与控制措施-以XX市海星水泥包装实业有限公司为例Pollution Analysis and Control Measures of Plastic Woven Bag Processing Project - XX Starfish Cement Packing Industrial Co., LTD. 武汉工程大学本科毕业(设计)论文 摘 要随着我国工业化的发展,以及城镇化和新农村建设的加速推进,塑料编织袋逐渐成为居民生活和工业生产中不可或缺的一部分,但是在带给我们便利的同时,塑料编织袋的使用也给环境带来了巨大的压力。“白色污染”已经成为我国不少城市急需解决的难题。本文主要针对海星水泥包装实业有限公司情况进行研究,熟悉现场的生产工艺,对其工艺进行污染分析,找出主要的污染源。通过广泛的资料搜集和研究,在深入了解我国塑料编织袋发展概况的情况下,针对现场污染的情况,提出适合企业实际情况的控制措施,为企业提供可行性的方案,最终改善企业的污染情况,减少对环境的污染,达到带动这个行业的发展的目的,从而实现清洁生产的目标。关键词:塑料编织袋; 生产工艺;污染分析; 控制措施;IAbstractWith the development of our country industrialization, urbanization and new rural construction accelerates, plastic woven bag has gradually become an integral part of life and industrial production.But while it bring us convenience, the use of plastic bag also brought great pressure to the environment. White pollution has become a problem needed to resolve a lot of cities in our country.Plastic bag was named 20th century human worst inventions: a plastic bag recovery value less in use except strewn on the streets of the city, tourist areas, water bodies, roads and railways on both sides resulted in Visual pollution, but also there is a potential hazard. Since 1966, has developed a plastic bag so far, rapid product development, has formed a assortment of variety, complete size products, quality has reached the level of similar products abroad, has a certain competitiveness in the international market. China plastic woven bag industry a wide range of applications involving vegetables and other agricultural products, packaging, food packaging, geotechnical engineering, tourism, transportation, household items, and other industries. According to the latest data released by the China show that plastic bags in 2011 of Asia reached 17.322 billion yuan market scale, an increase of 13.05%. Plastic woven bags made of polypropylene and polyethylene raw materials generally fall into, both of these materials are also widely used in various types of packaging products, produced the products due to the low cost and relatively high compressive strength and so on has been vigorously applied. Plastic woven bag production process is relatively simple, relatively low entry threshold, causing plastic bag manufacturers mostly small and informal, the production of plastic bags are often uneven, recovery is difficult, and caused great harm to the environment. How to reduce the use of plastic bags and discarded, increasing resource utilization, is the key to resolve the current conflict. This documentation is mainly focused in plastic woven bag production process analysis of pollution, according to the practice in the work place situation, and rational control measures, reducing the pollution of the environment.This article focused on the scene, the familiar scene of the production process, through extensive data collection and research , in -depth understanding of the development of plastic bags overview of the situation , particularly small and medium -sized, low -quality mixed characteristics and resource utilization , propose suitable control measures actual situation of enterprises , thereby improving the situation of enterprises, adjusted in accordance with the actual situation of enterprises , promote the use of resources in the industry , in order to achieve the goal of clean production .Keywords:plastic; production process; resource utilization; control measuresIII目 录摘 要IAbstractII第一章 文献综述11.1 塑料编织袋行业概述11.2 塑料编织袋对环境的危害21.3 塑料编织袋的污染现状31.4 塑料编织袋的污染控制面临的主要问题51.5 本文研究内容6第二章 塑料编织袋加工项目的工艺与污染分析72.1 企业概况72.1.1 企业基本情况72.1.2 企业生产设备和建设规模72.2 生产工艺流程92.2.1 使用原料和检测102.2.2 主要工艺技术方案122.2.3 生产工艺特点142.2.4 工艺流程简述152.3 污染分析172.3.1 废气、异味和粉尘172.3.2 废水172.3.3 固体废物182.3.4 噪声18第三章 塑料编织袋加工项目的污染防治措施193.1废旧塑料编织袋处理基本情况193.2 废旧塑料编织袋回收存在的问题213.3 塑料编织袋污染的控制措施223.3.1 制度上的改革223.3.2 科技上的创新233.3.3 国外经验的借鉴233.4 项目污染的控制设施243.4.1 粉尘防治243.4.2 噪声控制243.4.3 固体废物控制253.5项目回收废旧塑料的再加工253.5.1 废旧塑料生产汽柴油253.5.2 废旧塑料回收制管273.5.3 废旧塑料制成建筑保温材料283.5.4 废旧塑料制作仿藤席28第四章 总 结30参考文献32致 谢35V第一章 文献综述1.1 塑料编织袋行业概述塑料编织袋是美国人Paul Hogan(1919-1985)和RobertBanks(1921-1989)在1951年美国的菲利普斯石油公司发明,而后进行逐步的完善。20世纪30年代,HJaeque通过对聚氯乙烯薄膜拉伸研究发现生产切割纤维丝和裂膜纤维的新技术。50年代,OBRasmussen通过研究,利用薄膜挤出方法和拉伸设备,开始生产编织用纤维。到1965年,欧洲开始工业化生产单向拉伸扁丝,用以生产工业包装用编织袋。我国自1966年开发出塑料编织袋至今,产品发展迅速,已形成花色品种多样、规格尺寸齐全的系列产品,品种质量已达到国外同类产品的水平,在国际市场上具有一定竞争力。国内塑料编织袋行业生产企业相对较多,特别是中小型企业居多,产品同质化与投资盲目化现象严重,这使得
