Urban Waste Landfill Sites Ecological Restoration Technology Research

This paper, which is based on the environmental pollution analysis of urban rubbish sites, has studied ecological restoration technology for urban rubbish sites using by ecological principle and plant-restore mechanism, The ecological restoration technology of discard rubbish sites put forward in this paper is not only the traditional vegetation recovery but combined with corresponding engineering measures. It is a comprehensive ecological recovery technology about"phytoremediation and recirculation of treated leachate". The main process of this technology are: the investigation of landfill sites condition; the topsoil of landfill sites; the choice of vegetation and planting experimentally; leachate recirculation as well as some other project measures . In the course of choice of vegetation , it is essential to find growth rapid , adaptability strong,lean fastness local vegetation, and establish gradually grass-frutex-arbor community structure;The"phytoremediation + recirculation of treated leachate"technology is a new method which can optimize the efficience of restoration as well as control the contaminants of discard rubbish site. In this paper, we put forward a restoration technical scheme for one rubbish site in Baoding, based on its special circumstance. In this paper we make great efforts to control the pollution and to maintain the zoology balance of waste landfill sites by applying ecology recovery theory and reasonable engineering measures and finally establish a mutual-action ecosystem.
