- 摘要：在上海市老港垃圾填埋场建造了一座面积为3000m2, 高度为4m, 内填生活垃圾10800t的小型卫生填埋场.对该卫生填埋场进行了40个月的监测, 分析了垃圾中的总糖、总碳、挥发性物质和有机碳、生物可降解物含量(BDM)、粗纤维含量与填埋时间的关系.同时, 也对1991年至1994每年4月份的填埋单元垃圾组成进行了分析.通过数学拟合, 预测了填埋单元封场后的若干年内垃圾组成, 对填埋场稳定化程度和垃圾矿化程度进行了判断.结果表明, 该场的稳定化时间大约为22—23年, 届时, 该场的垃圾基本上达到无害化和稳定化, 绝大部分可降解的有机物得到充分降解.
- Abstract：A large scale experimental landfill with an area of 3000m+2 (50m×60m) was constructed in situ in Shanghai Refuse Landfill in April 1995. The refuse height is 4m and 10800 tons of refuse was placed in the experimental landfill. Contents of Biodegradable Matter, volatile substance (weight loss under burning), organic carbon, cellulose and total sugar in refuse were monitored from April 1995 through October 1998. The mathematical simulation formulas between these parameters and refuse age were developed and justified by corresponding parameter for refuse taken in the closed landfill units from 1991 to 1994 in the Landfill. The long term predictions for the refuse compositions were made using the formulas. It was predicted that the refuse might be fully mineralized after 22—23 years of stabilization. Hence it can be considered that the time for the Landfill to reach a high stability after closure is around 22—23 years from the viewpoint of refuse composition.
