Study On Ecological Restoration Planing Of The Landfill In Bengbu City,Anhui

Since the 21 st century,with the rapid development of China's economy and the continuous acceleration of urbanization,urban domestic waste has grown dramatically.In order to improve this situation,the state has built a large number of landfill disposal bases during the "tenth five-year plan" and effectively solved the problem of urban garbage disposal.But since the use of landfills is generally 15 to 20 years,the landfills that have been built during most of the "fifteen projects" in recent years have reached the service life and are about to be dealt with.How to develop the landfill site after sealing field and improve the ecological environment surrounding landfill site become the important research content.Based on bengbu landfill as the research object,this paper discusses the development and utilization of sealing after the land route,the key research in greening reform as the core of ecological restoration planning in jobsite,the main research results are as follows:1.On the analysis of the research at home and abroad a successful city landfill after the experience of ecological restoration,combining the present economic and technological level,suitable for small and medium-sized cities in our country are summarized ecological restoration methods of landfill site.That is,the greening of the landfill site is mainly,and the garbage disposal of other areas in the field is supplemented.2.The landfill site belongs to the comprehensive disposal sites,there are many garbage disposal area,reorganize quantity is larger,should be based on original rectification expansion,cooperate with the waste incineration power plant construction,planning and construction on the stage.First phase of the construction will mainly in northern area of garbage incineration power plant,the sludge treatment plant,construction waste treatment plants such as garbage disposal area for integration,and transform the landfill area in the south of ecological park,through the leachate treatment and the prevention and control,landfill gas collection and the corresponding technical means such as plant ecological restoration,reduce pollution,to reach a benign growth of the ecological system.Second phase reconstruction mainly increase the intensity of ecological industry,such as the recovery of contaminated soil using the ecological regulation,landfill gas and leachate recycle,etc.,at the same time expanding the scope of the intensity of greening,add other regional landscape construction of the project,rich landscape forms,to further promote the process of ecological restoration.3.Explores the landfill closure after land utilization way,has transformed the landfill area for the park and building area for the local and surrounding urban ecological environmental education demonstration base,realize the key urban solid waste resource utilization,ecological restoration and environmental protection and cultural education three big functions.4.This study by adopting the technology of ecological restoration to the landfill related processing technology as the guide,complete the bengbu landfill closure after ecological restoration planning,of landfill ecological restoration planning in our country,providing a certain reference.
