渗滤液调节池容积计算的探讨

Discussion on Calculation for Volume of Leachate Regulating Tank

考虑到《城市生活垃圾卫生填埋技术规范》推荐使用的按多年逐月平均降雨量计算渗滤液产生量的标准相对较低,分析了渗滤液产生量的多种影响因素和理论计算方法,并以某工程为例,在渗滤液多年调节情况下,采用年均降雨计算出渗滤液处置规模,再在该规模基础上,采用历年最大降雨确定调节池容积。实践证明,该法能满足填埋场降雨季节性变化。

Considering low standard of calculating leachate output by years of average monthly precipitation recommended in Technical Code for Sanitary Landfill of Municipal Domestic Refuse, the paper analyzes many effecting factors and theoretical calculation methods of leachate output, taking a certain project as an example, annual average precipitation is adopted to calculate disposal scale of leachate under the condition of years of regulating, on the basis of which the maximum precipitation over the years can be used to determine volume of regulating tank. It proved that this method can meet seasonal variation of landfill rainfall.
