Method for causing biogas digester to quickly enter into anaerobic state

The invention discloses a method for causing a biogas digester to quickly enter into an anaerobic state and relates to the technical field of anaerobic treatment of the biogas digester. The method comprises the steps of cleaning the biogas digester, feeding, preparing an anaerobic environment and sealing. The steps are specifically as follows: 1) cleaning the biogas digester, namely cleaning the biogas digester with clean water, extracting the liquid in the biogas digester and achieving the state basically without odor; 2) feeding, namely putting the materials into the biogas digester treated in the step 1); 3) preparing the anaerobic environment, namely taking a flammable fuel, putting into a wide-mouth container, igniting and putting the container into the biogas digester; and 4) sealing, namely while burning the fuel, covering on a biogas digester cover and performing sealing treatment. After the pretreatment, the biogas digester can quickly enter into the anaerobic state and the quick growth of the anaerobic micro-organisms is boosted. According to the method provided by the invention, the operation is simple and convenient as well as safe and reliable, the biogas digester can quickly enter into the anaerobic state, and the growth of the micro-organisms and the quick generation of the marsh gas are boosted.
