(1) The water seal height of the low-pressure floating cover biogas tank should be maintained, and anti-freezing measures should be taken in cold areas;
(2) Biogas should be fully utilized, and the biogas to be discharged should be burned by torch;
(3) The gas storage volume and pressure of the biogas tank should be checked and recorded on time;
(4) The condensed water in the steam pipe and biogas pipe connected to the biogas tank should be discharged regularly;
(5) The desulfurizer in the desulfurization device should be regenerated or replaced regularly;
(6) The pH value of the water in the water seal tank of the biogas tank should be measured regularly. When the pH value is less than 6, the water should be replaced;
(7) The pressure of the biogas tank should be 2500~4000Pa.
