[0044] The present invention proposes an environmental monitoring method in a super-large-scale anaerobic tank, which specifically comprises the following steps:

[0045] S100. A sensor is arranged inside the anaerobic tank.

[0046] A temperature sensor, a pressure sensor, a pH sensor, a liquid height sensor and a solid concentration sensor are arranged inside the anaerobic tank.

[0047] The temperature sensor is used to monitor the temperature in the anaerobic tank in real time to avoid the death of bacteria due to inappropriate temperature, thereby affecting the fermentation efficiency in the anaerobic tank. A plurality of temperature sensors are arranged inside the anaerobic tank. The plurality of temperature sensors are arranged on the inner wall of the anaerobic tank in a certain arrangement rule. The plurality of temperature sensors are numbered N to collect the temperature of multiple positions in the anaerobic tank.

[0048] The pressure sensor is used to monitor the pressure inside the anaerobic tank in real time to avoid danger caused by excessive pressure in the tank.

[0049] PH sensor is used to monitor the PH value in the anaerobic tank. In the anaerobic tank, bacteria are usually used to ferment food waste. The PH value needs to be within an appropriate range, usually 6.5-7.5. When the PH value is too high or too low, the fermentation efficiency will be low.

[0050] Solid concentration sensor is used to monitor the solid concentration in the anaerobic tank to adjust the speed and timing of material addition.

[0051] The liquid height sensor is used to monitor the height of the liquid in the anaerobic tank to avoid liquid leakage due to excessive liquid height.

[0068] S405. Determine whether the pressure in the anaerobic tank collected by the pressure sensor is greater than a threshold value a. If not, execute step S406. If yes, turn off the agitator and further collect the temperature in the tank. When the average value of the temperature in the tank is greater than P1, further determine whether the liquid height H collected by the liquid height sensor is greater than a threshold value b.
