技术简介

该技术池底建设材料选用高密度PE膜材，厌氧密封性好，抗腐蚀性高，膜材埋入地下可达到50年不坏，可以循环利用，迁移方便，节约成本。双层覆膜之间通过微量鼓风保持外层膜抗风能力，在寒冷地区还可以提高沼气工程的保温能力。

Introduction

With this technology, a high-density PE membrane material is selected as the construction material at thebottom of the pool. This membrane material has good anaerobic sealing performance and high corrosionresistance. lt can be buried underground for 50 years without damage, can be recycled, and is convenient tomove, thus saving costs. The wind resistance of the outer membrane can be maintained by micro-blastingbetween the two membrane lavers, and the thermal insulation capacity of biogas projects can also be improvedin cold areas.
