Based on the studies made in the developed countries about siting, design and monitoring of landfill disposal of solid waste, some environmental geologic problems arc discussed, especially in soil material quality, unsaturated zone thickness and basic geologic criteria for suitable sites.
As the results of the experiments illustrated,the environmental influence potential of landfill disposal,incineration disˉposal and synthesized disposal are3.59×10 -2 、5.87×10 -2 and1.90×10 -2 respectively.
On the basis of primarily discussing on present situation and development of waste discoal in Ningbo, we consider that urban waste disposal integrated planning should be made and the research of waste incineration and synthetic utilization must be based on waste landfill disposal.
Based on the studies made in the developed countries about siting, design and monitoring of landfill disposal of solid waste, some environmental geologic problems arc discussed, especially in soil material quality, unsaturated zone thickness and basic geologic criteria for suitable sites.
In principle, arsenic can be removed as a marketable product (copper arsenate for wood preservation) or as stable precipitate compounds suitable for safe landfill disposal under existing U.S.
Landfill disposal opportunity costs, operating costs, and competitive disposal outlets are not significant in explaining early or later adoption.
On the other hand, there were potentially significant pathways associated with landfill disposal of geothermal residues because of the considerable potential pollution impact of leachate on soil and groundwater quality.
From the tier-2 analysis, none of the possible exposure pathways associated with the landfill disposal of ACW was found to be potentially significant.
A three-tier risk assessment study was therefore conducted to evaluate the landfill disposal of asbestos-containing waste (ACW) and geothermal residues.
Based on the studies made in the developed countries about siting, design and monitoring of landfill disposal of solid waste, some environmental geologic problems arc discussed, especially in soil material quality, unsaturated zone thickness and basic geologic criteria for suitable sites. In the end, some suggestions about solid waste administration in China arc made.
Based on the result of determination of surface water quality in Tongpenpu Landfill, the surface water was classified into some types by means of fuzzy clustering methord in this study. An preliminary analysis was made concerning surface water influenced by waste landfill disposal.
In this paper,an important engineering type of the world urbans construction today sanitary waste disposal engineering is discussed.The current main types for the waste disposal is summarized,the distinctive advantage of sanitary landfill disposal method from them is analysed and the function of every parts is introducted.The various chemical and biochemical processes and their changes are discussed.That the landfill body is its core part and the majorizing design of the landfill structure...
In this paper,an important engineering type of the world urbans construction today sanitary waste disposal engineering is discussed.The current main types for the waste disposal is summarized,the distinctive advantage of sanitary landfill disposal method from them is analysed and the function of every parts is introducted.The various chemical and biochemical processes and their changes are discussed.That the landfill body is its core part and the majorizing design of the landfill structure is a key for the controlling pollution to the geological environment are pointed out,and a set of the technical line and systematic method used majorizing design to landfill structure are proposed.Finally,in accordance with the present problems and the lack of the research, the opinions and suggestions are put forward.
