摘　　要：以8m3圆筒形沼气池为例,设计气压为3.9～7.8kPa(40～80mmH2O),对双级调压水压式沼气池的气压与贮气量的关系进行了研究,并用Matlab7.0进行处理。结果表明:在水压间有效容积相同的情况下,当沼气池内压力在0～3.9kPa之间时,双级调压水压式沼气池单位体积贮气量变化所引起的压力变化较单级明显;当池内压力在3.9～7.8kPa之间时双级单位体积贮气量变化所引起的压力变化较单级平稳,且水压间的体积较单级小,双级调压水压式沼气池更适合于沼气的推广利用。8m^3 cylindrical digesters as an example, the design pressure is between 3.9 kPa and 7.8 kPa, approaching the relationship of the pressure and the gas storage of the tow step modulation water pressure anaerobic digester, and dealing by Matlab 7.0. The results show that as the valid volume are the same, the unit volume changes caused by pressure changes of the tow step is more obvious than the one step at the between 3.9kPa and 7.8kPa, and the water pressure room pressure between 0 kPa and 3.9kPa, steadier at the pressure of tow step is short in size. the tow step is more suitable for the promotion of biogas use.
