A study on the thickness of covering for landfill sites without top lines was conducted at the Hudao landfill site in Qingdao City,and the thickness for landfill site with the top lines and outward form for the covering were also discussed.The results suggested that the thickness of covering should be 1.5m and 0.20 to 0.50m for landfill sites with and without top lines respectively.The outward form with a slope of 1:3 and a community of grass-shrub-tree structure was recommended.

以青岛湖岛垃圾填埋场为试验点,研究了非封闭式填埋场的表面覆盖层的厚度,并对封闭式填埋场的表面覆盖层厚度和垃圾填埋场生态工程表面覆盖的外观设计进行了探讨。对于非封闭式填埋场,实验结果表明:表面覆盖层的厚度应在020~050m之间;对于封闭式填埋场,表面覆盖厚度应大于15m。垃圾填埋场的外观以坡度为1∶3的凸状设计较为适宜。

In order to treat urban landfill leachate which contains COD(2400-3300mg/L),SS(400-500mg/L),an anaerobic aerobic biological process is used.After the process,COD and SS in the leachate become 119~185mg/L and 50~76mg/L.The study shows that the technological process has a good result.

采用厌氧-好氧生物法处理COD的质量浓度(ρ(COD))为2 400~3 300 m g/L,SS的质量浓度(ρ(SS))为400~500 m g/L的城市垃圾填埋场渗滤液。实验结果表明,经该工艺处理后的出水ρ(COD)为119~185 m g/L,ρ(SS)为50~76 m g/L,处理效果良好。

Through LFG extraction trial onsite in Shenzhen city, the rate of LFG generation andLFG component have been obtained for Yulongkeng landfill site. The results show that LFG was com-posed of CH4, O2, CO2, and other gas, the concentration of these gases were 62. 1%, 1. 1%' 34. 8 %,1. 9 % respectively. The gas output was 188. 7m3/t in ideal condition. The equation of LFG generation rate was Ri = 21. 5e-0. 12i. The calculation of LFG output per year shows that gas production is inpeak period at present. The...

Through LFG extraction trial onsite in Shenzhen city, the rate of LFG generation andLFG component have been obtained for Yulongkeng landfill site. The results show that LFG was com-posed of CH4, O2, CO2, and other gas, the concentration of these gases were 62. 1%, 1. 1%' 34. 8 %,1. 9 % respectively. The gas output was 188. 7m3/t in ideal condition. The equation of LFG generation rate was Ri = 21. 5e-0. 12i. The calculation of LFG output per year shows that gas production is inpeak period at present. The gas production would last for about 30 years. When this processterminates, the site would be stable and harmless entirely.

通过对现场抽气试验的数据整理及理论计算,得出了深圳市五龙坑垃圾填埋场的填埋气体成分及产气规律。结果表明,场区内填埋气体含量分别为CH4:62.1%,O2:1.1%,CO2:34.8%,其余气体:1.9%;理想条件下填埋场的产气量为188.7立方米/吨,垃圾产气率方程为Ri=21.5e-0.12i;根据产气速率方程计算了填埋场历年的产气量,结果表明填埋场目前正处于产气高峰期,整个产气过程约持续30年,填埋场才能达到稳定、无害化。
