生态农业示范区中一种改进型高效沼气发酵装置的设计与应用

Design and application of an improved type of higheffective biogas ferment device in the ecoagricultural demonstration place

根据生态农业示范区的实际情况，力求创造沼气发酵微生物生存、繁殖的最佳环境条件，同时把各种通过实践证明行之有效的提高产气率的措施尽可能有机地结合起来，改进设计、修建了一种具有效率高、管理方便、造价低的沼气发酵装置．经连续２ａ跟踪测试，其产气率均在０．３ｍ３ｄ－１以上，应用取得了很好的能源、经济和生态效益．

Based on the local conditions of ecoagricultural demonstration place , an improved type of higheffective biogas ferment device was set up to provide and keep the optimal environment for living and propagation of biogas ferment microbes. Meanwhile, the various feasible methods to increase biogas production were synthetized to improve design and increase effect, simplify management and decrease cost. According to the test for 2 years, the biogas production rates of the device were beyond 0.3 m3·d-1 and energy, economic and ecological effects were obtained. 
