老挝户用沼气池发展及相关技术研究简述

Brief Introduction to the Development of Household Biogas Digesters and Related Technology in Laos

本研究介绍了老挝国内各种类型的户用沼气池的建造技术、建造成本、建造材料以及模型设计等方面。老挝国内现有的户用沼气池可以分为五种类型:采用德国与中国技术的固定圆顶型沼气池、采用中国技术的玻璃纤维沼气池、气缸柱型砖混沼气池、老挝国内的Sunlabob公司所设计的沼气池以及老挝与荷兰合作的基于GGC模型基础上的沼气池。本研究主要针对以上五种类型的沼气池建设情况进行介绍分析,并总结出老挝户用沼气池在发展过程中存在的主要问题,最终提出了一定的解决对策,以期日后为老挝户用沼气池的发展及推广应用做铺垫。

This essay will introduce each biogas digester construction technology,construction cost,material and model design specifically in Lao PDR.Currently,many countries are supporting and promoting the development of renewable energy,Laos government also treats renewable energy as an important part of national development,which can increase the level of domestic rural area development.There are five types of biogas plants existing in Lao PDR rural area: fixed dome type biogas plant adopted from German and Chinese models,Chinese biogas fiberglass plant,cylinder shape brick biogas digester,Sunlabob biogas plant and Lao-Neth biogas plant modified from GGC model.This essay introduced these five types of biogas digester respectively,and summed up the main problems in the development process of Lao household biogas digesters,and finally put forward some solutions,in the hope of paving the way for the development and promotion of household biogas digesters in Laos.
