[0039] The specific implementation of the present invention will be described below with reference to the drawings and embodiments:
[0040] As shown in the figure, it shows the specific implementation of the present invention. The method for generating biogas by utilizing anaerobic digestion of domestic waste as a resource includes the following steps:
[0041] (1) Crushing; crushing domestic garbage to a particle size less than or equal to 200mm;
[0042] (2) Squeezing; conveying the crushed garbage to the squeezing device for squeezing and separating into dry base and wet base;
[0043] (3) Dry base treatment: The dry base obtained by pressing is sent to a waste incineration plant for incineration and power generation treatment;
[0044] (4) Wet base treatment; the wet base obtained by pressing is sent to the light impurity separation device and the heavy impurity separation device in turn for separation and removal of light impurities and heavy impurities in the wet base; the separa...
