卫生填埋场导气沟槽间距的选择,关系到填埋场运行费用、填埋操作和填埋场的容积损失等.介绍了在保证导气效果的前提下,沟槽间距的大小的计算方法.同时讨论了影响间距的各种因素:垃圾层中最大允许压力、垃圾层的透气性能、垃圾的产气速率等.所得的结论也可用来指导已运行填埋场的改造.
The selection of air guide trench spacing in sanitary landfills is related to the operating costs of landfills, landfill operations and volume loss of landfills. It also describes the calculation of the size of trench spacing under the premise of guaranteeing the effect of air conduction. Methods. Various factors affecting the spacing were also discussed: the maximum allowable pressure in the refuse layer, the air permeability of the refuse layer, the gas production rate of the garbage, etc. The conclusions obtained can also be used to guide the reconstruction of the landfill.
