摘　　要：猪场污水贮存过程中会产生大量温室气体,为测定污水预贮存过程中的温室气体排放情况,该实验利用静态箱法对四川某猪场的三格式污水贮存池进行了温室气体排放情况的监测。试验结果表明:一、二、三级贮存池温室气体CO2排放当量分别为555 g·m-2h-1,555 g·m-2h-1,279 g·m-2h-1,经过分级贮存后,温室气体排放明显减少;3个贮存池排放主要的温室气体均是CH4,其CO2排放当量分别为522 g·m-2h-1,526 g·m-2h-1,266 g·m-2h-1。CH4的贡献率分别达到94%,95%,95%,控制污水贮存过程中的CH4排放是温室气体减排的重要方法。Much greenhouse gases （GHGs） will be emitted during the piggery wastewater pre-storage. To monitor the GHGs emission, the static chamber method was used to measure the GHGs emission flux, and a storage tank with three grading chambers was adopted. The experiment results showed that the CO_2 equivalent GHGs emission of the three cham- bers were 555 g·m^-2h^-1 ,555 g·m^-2h^-1 ,279 g·m^-2h^-1 respectively. After grading pre-storage, the GHGs emissions gradually became less. The main GHGs contributor was CH_4, and its CO_2 equivalent emission were 522 g·m^-2h^-1,526 g·m^-2h^-1, 266 g·m^-2h^-1 for the three chambers respectively. CH_4 emission account for 94%, 95%, 95% of total GHGs, respective- ly. Control of CH_4 emission for pre-storage process could be an effective mitigation method.
