我国废铅酸蓄电池污染防治技术及政策探讨   总被引:3,自引:0,他引:3  
废铅酸蓄电池回收环节产生的废渣、铅酸污泥等属于危险废物,必须按照危险废物进行管理;而废铅酸蓄电池铅回收过程也会产生二次污染,其生产过程和管理不当会产生严重的环境污染。本文在分析我国再生铅生产工艺技术现状、废铅酸蓄电池资源再生过程污染源的基础上,对废铅酸蓄电池资源再生过程污染源治理和污染预防措施以及目前废铅酸蓄电池铅回收相关政策和管理要求进行了较为系统的分析和总结。  相似文献

废荧光灯管中的有害物质如果处置不当,会对人体健康和环境造成危害。目前国内大部分废荧光灯管未得到无害化处置,主要在指定的法规、有效的政策以及完善的运营机制方面存在很多弊端,应引起社会各界的关注和政府部门的重视。本文结合国内外废荧光灯管回收处置现状,针对存在的问题,提出源头控制、分类收集、多渠道回收、建立资金及资金补贴机制以及技术手段措施,为从根本上解决废旧灯管回收难的问题,并探索社会源危险废物的管理提供对策建议。  相似文献

江苏省废无机酸的产生总量大,且逐年增加。废无机酸具有腐蚀性、毒性、不稳定性等危险特性,如不进行合理处置便排入环境中,危害极大。江苏省废无机酸的产量与城市区域分布、产业布局有着密切的关系。废无机酸处置及利用企业与废无机酸的产生情况有较密切的关联。针对不同特性的废无机酸,适合采用不同的处置或利用工艺。废无机酸作为危险废物可采用中和法实现无害化处置或采用浓缩回收法等工艺进行资源化利用。  相似文献

四川省固体废物处置现状及对策探讨   总被引:2,自引:0,他引:2  
我国《固体废物污染环境防治法》(以下简称《固废法》)自1996年4月1日颁布实施8年来,在实际工作中面临了许多新的问题。因此,立法机关重新修订了《固废法》,并于2004年4月1日起生效。由此可以看出,固废的污染防治越来越得到重视。我省固体废物产生量近年来一直呈上升趋势,但其综合利用率和处置率偏低,造成的污染日趋严重。本文分别对我省一般工业固废、危险废物和生活垃圾处置现状进行分析,提出提高我省固废处置几点建议。  相似文献

The current status of the treatment and disposal of hazardous wastes in China is summarized on the basis of the results of the Declaring and Registration Project initiated nationally in 1995. A principle framework for the sound management of hazardous wastes is proposed, which includes three levels of technical solutions. Large-scale enterprises are encouraged to recycle, to treat, and to dispose of wastes by means of constructing facilities, and to have their extra capacities available to the public for a reasonable fee. Municipal governments, provincial governments, and the Central Government are to plan and construct centralized facilities to recycle, treat, and dispose of wastes. For a solution at the manufacturing level, recycling is identified as the main approach. Centralized facilities at the municipal level will mainly focus on special wastes that are unsuitable to transport and store, such as hospital waste, and for the technical solution at this level, incineration and recycling are identified as the main approaches. For the technical solution at the provincial and national levels, landfill and incineration are identified as the main approaches. Based on this principle and the current available data on hazardous wastes, a preliminary plan for the spatial distribution of cross-provincial centralized treatment and disposal facilities of hazardous wastes is presented. The construction of approximately nine cross-provincial comprehensive facilities is proposed. A priority list for the construction of these planned facilities is also presented.  相似文献

Since the publication of Rachel Carson's Silent Spring in 1962 there has been a rapidly growing public concern over widespread contamination of the environment with hazardous wastes. In recent years scientific findings on the ecological effects of various hazardous substances have posed several important questions. What exactly are hazardous wastes? Can these substances be disposed of in a technically feasible, economical, and safe way with assurance that they have been permanently eliminated from the ecosystem? What compositional alterations or movements of the hazardous wastes occur in water, soil, or air systems? What effect will these wastes have on the water, soil, or air systems? What effect will these wastes have on the water, soil, or air properties? Consequently, a University of Louisville study has developed a relevant definition of hazardous wastes for the Environmental Engineering profession together with priority of concern rating systems to delineate the degree of environmental impact imposed on a total ecosystem by a hazardous waste and the feasibility of disposing of hazardous substances at specific landfill sites. It is felt that refinements of the priority of concern rating systems offered here may provide a sound basis from which procedural decisions may be structured to establish future national hazardous waste disposal sites.  相似文献

Construction and demolition wastes (CDW) have increasingly serious problems in environmental, social, and economic realms. There is no coherent framework for utilization of these wastes which are disposed both legally and illegally. This harms the environment, contributes to the increase of energy consumption, and depletes finite landfills resources. The aim of this paper is to evaluate the impacts of two alternatives for the management of CDW, recycling and disposing. The evaluation is carried out through developing a dynamic model with aid STELLA software by conducting the following steps: (1) quantifying the total cost incurred to mitigate the impacts of CDW landfills and uncollected waste on the environment and human health; (2) quantifying the total avoided emissions and saved energy by recycling waste; (3) estimating total external cost saved by recycling waste and; (4) providing a decision support tool that helps in re-thinking about waste disposal. The proposed evaluation methodology allows activating the stringent regulations that restrict waste disposal and developing incentives to encourage constructors to recycle their wastes. The research findings show that recycling CDW leads to significant reductions in emissions, energy use, global warming potential (GWP), and conserves landfills space when compared to disposal of wastes in landfills. Furthermore, the cost of mitigating the impact of disposal is extremely high. Therefore, it is necessary to recycle construction and demolition wastes.  相似文献

危险废物对环境或者人体健康会造成有害影响,有效地预测其产量是优化管理和合理处置的重要依据。以2008~2016年成都市危险废物产生量为基础,通过数据带入和整合及综合各参数因子的影响,利用人工神经网络模型预测方法客观反映并预测成都市危废产量的变化趋势。结果表明该模型预测2017~2018年成都市危险废物年产量分别达到24.46万t和26.88万t,模拟精度偏差低。因此,人工神经网络模型可以作为一种预测危险废物产生量的工具,其预测结果可以为职能部门提供决策参考。  相似文献

Industrial and medical wastes constitute a larger part on what is known as ‘hazardous wastes’. The production of these wastes is and will continue to be an on going phenomenon as long as human civilization persists. The health impacts of direct and indirect exposure to hazardous wastes include carcinogenic effects, reproductive system damage, respiratory effects, central nervous system effects, and many others. Today, many developed countries have legal provisions with regard to proper management of hazardous wastes. Tanzania, like many developing countries, has little emphasis on the proper handling and disposal of hazardous wastes. There is a serious inadequacy in handling industrial and medical solid wastes in the Dar es Salaam City. Improper waste deposition is increasingly becoming a potential public health risk and an environmental burden. Due to poor control of waste, industrialists and hospital owners are not well checked on how they handle and dispose of the wastes they produce with the result that many hazardous wastes reach the Vingunguti dumpsite without notice. Data on waste generation in Dar es Salaam is also inadequate, making it difficult to plan an efficient solid waste system. Promotion of public awareness, legislation and regulations enforcement and establishment of a proper sanitary landfill are considered to be principal remedial measures to ensure sound environmental maintenance. This paper summarizes the findings of the study on the practices of industrial and medical waste management in Dar es Salaam. The author aims to express the inadequacy in hazardous waste management and suggests possible measures to be applied in order to rectify the situation.  相似文献
