生活垃圾填埋场封场后土地利用.pdf

化时间、 粒度有很大的关系。当陈化超过6 个月或粒 度 10 a 的填埋单元作 为老港场的苗圃基地 。在扩大种植面积时,所培植的 苗圃不仅可以节省购买苗木费用, 而且自行培植的苗 木适应老港场的环境 ,成活率高。 3 大棚温室和盆景园的开辟 选择一些稳定化 程度高、 封场时间 10 a 的填埋单元作为老港场的大 棚温室和盆景园 ,培植的盆景可供场区管理部门装饰 和展览用, 尤其是重大节日的大批量使用 ,为老港场 外出购置盆景节省了经费 ,具有经济效益。 2. 3. 4 科研基地 科研人员对老港填埋场封场土地仅围绕种植方 面已开展了多项科学研究课题 , 如 ①利用老港场填 埋龄在8 年以上的矿化垃圾种植植物 ,研究植物的生 长情况,及植物重金属的富集情况 。 ②填埋场种植植 物后重金属的迁移变化情况, 以证明所种植物能否进 入食物链 。 ③ 填埋单元的封场时间与所种植物的种 类及生长情况。 ④培植外来植物物种和珍稀植物物 种。 ⑤ 填埋场种植与生态效应的关系 。 ⑥ 园林绿化 规划研究等等。 3 结束语 1 垃圾填埋场封场后土地开发利用 ,要结合当 地科技、 经济、 环境、公众意识及现状等方面进行统一 规划 ,分步实施 。 2 不同封场时间的填埋场 ,其稳定化程度不一, 对其土地的开发利用要区别对待。 3 垃圾填埋场封场后土地用于种植植物 ,具有 很好环境效益、经济效益和社会效益。 参考文献 [ 1] Ayala Misgav, Noa Perl, Yoram Avnimelech.Selecting a compatible open space use for a closed landfill site.Landscape and Urban Planning ,2001, 55 95 -111.

Over 2 of alkalinity, parts of CaO are free CaO in BOF slag. Free CaO is the main component affecting its distensibility of BOF slag. The distensibility of BF and BOF slags was measured using steam test and the effects of size and ageing time on the distensibility were investigated. This gives evidence for application of BF and BOF slags. Keywords steel slag, free CaO, steam test and distensibility APPLICATION OF CLOSED DOMESTIC REFUSE LANDFILLS Li Xiong Xu Dimin ZhaoYoucai et al 64 Abstract By application of closed landfill compartment in Shanghai Refuse Landfill, there are lots of ways to use each closed landfill compartment in different time. Planting is one of the best ways for applications of closed landfill sites. Which will have excellent environmental, economic and social benefits. Keywords refuse landfill, planting and environemnt USE OF IMPERMEABLE MATERIALS FOR REFUSE LANDFILLS IN JAPAN Xu Sifa Yang Yang 68 Abstract It is introducedthat the structure of impermeable system and classification of impermeable materials for landfillsin Japan, aswell as the use of all sorts of impermeable materials in Japan recently . The structure of impermeable system of landfill that is suitable for China is also proposed according to the actual conditions in China. Keywords refuse landfill, impermeable system and impermeable materials DETECTION OF NICKEL USING LOW -PRESSURE ION CHROMATOGRAPHY AND CHEMICAL LUMINESCENCELuoYu Huang Meixiu 71 Abstract It was attempted under certain conditions to detect transition metal ions and conduct a study on determination of trace nickel by low-pressure ion chromatography of mobile phase and chemical luminescence. Keywords low -pressure ion chromatography, inorganic mobile phase, chemical luminescence, combined technology and nickel ion ON -LINE MONITORING SUBSYSTEM OF SULFUR DIOXIDE MASS CONCENTRATION Wang Shilong Wang Lina Wang Zhicheng 74 Abstract The on -line monitoring system of sulfur dioxidein smoke consists of two subsystems. One is subsystem to monitor the mass concentration of sulfur dioxide, the other isused to monitor the velocity and rate of flow of sulfur dioxide. The author introduces principles and plan of monitoring in the system and discusses fully the subsystems to on-line monitor the mass concentration of sulfur dioxide sufficiently . Keywords boiler smoke, sulfur dioxide, on -line monitoring and mass concentration DISCUSSION ONPROBLEMS OF DETERMINING TRACE HEAVY METALS BY FLAME ATOMIC ABSORPTIONSun Cuiling Xin Honglin Feng Xueyang 76 Abstract It was explored through experimentation that the optimal conditionsof determining trace heavy metals by flame atomic absorption, as well as the s of eliminating interference liquid, which provides excellent experience for measuring accurately the content of trace heavy metals. Keywords flame atomic absorption, trace heavy metal, experiment and interference APPLICATION OF FUZZY SYNTHETIC UATING MODEL FOR ASSESSING WATER QUALITY OF LEAN RIVERWan Jinbao Hou Deyin Wan Xing et al 77 Abstract Based on the principle of fuzzy mathematics, the fuzzy synthetic uating model for assessing surface water quality was established. The model could not only ernbody systemic and synthetic characters but also simplify the calculation. At last, the modelwas applied to assess water quality of Le an River, which supplied scientific evidence for controling pollution. Keywords fuzzy , synthetic uation, model, water quality and Le an River APPLICATION OFMATTERELEMENTMODELBASEDONENTROPYWEIGHTTO UATION OF EUTROPHICATION OF LAKESRao Qinghua Zhang Jiangshan 80 Abstract Entropy weight is used to calculate the weight of uating indicators, then a matter element model is also adopted to uate the eutrophication of lakes. The results are comparedwith those of attribute identifying model and the fuzzy administering function, the results indicate that the matter element model is feasible for uating the eutrophication of lakes.
