A glass fiber reinforced plastic biogas tank includes a biogas storage chamber (1), a fermentation chamber (2), a feeding pipe (3) and a biogas discharging pipe (4) both of which are connected with the biogas storage chamber (1), and a stirrer (5). An annular hole (6) is set on the outer wall of the biogas storage chamber (1), the stirring shaft (7) of the stirrer (5) is extended into the fermentation chamber (2) through the annular hole (6), stirring blades (8) are set on the section of the stirring shaft (7) which locates in the fermentation chamber (2), a block cover (9) is installed on the section of the stirring shaft (7) out of the fermentation chamber (2), and the diameter of the block cover (9) is not less than the inner diameter of the annular hole (6). A discharging pipe (10) is provided in the fermentation chamber (2), a discharging cover (11) is installed in the exit of the discharging pipe (10), and at least one one-way biogas guide pipe (12) is installed on the discharging cover (11). The one-way biogas guide pipe (12) penetrates through the discharging pipe (10), and is in communication with the biogas storage chamber (1). The biogas tank has high biogas yield, well sealing effect, and can not volatilize easily.
