Strengthening day-to-day management of biogas digesters is a key measure to increase biogas gas production and maximize biogas benefits. It is a central link in the construction, management, and use of biogas tanks. To achieve scientific management of biogas digesters, attention should be paid to the following aspects: work: 1. Diligent feeding and discharging shall ensure that the biogas digester continuously stabilizes the real estate gas. It is necessary to add and replace the fermentation raw materials frequently. For the three-batch biogas digester that is fed automatically, the material should be discharged from the low pressure direction frequently, and the volume of the air tank should be kept to a sufficient volume. If it is artificially fed, it must be diligently diligent. Usually, a new material should be added in about one week, and the number of advances should be advanced. New materials are mainly supplemented with human and animal excrement. 2. Regularly inspect the biogas digesters used in pipelines, pool covers, etc. for normal leakage. When the gas production volume is reduced for a period of time or if the effect of gas usage is not good, the biogas digesters should be carefully checked for leaks. Whether the air pipe, switches, pipes, etc. are leaky, if any problems are found, they are repaired or replaced in time, and the outdoor underground pipeline water must be inspected and removed regularly. 3, regular large refueling using biogas digesters such as human and animal excrement fluid fermentation, usually less in and out less, so that the combination of biogas slurry and biogas residue, about 3 years should be a large refueling time. Biogas digesters using rice straw and wheat straw as raw materials for fermentation are generally reloaded 1-2 times each year in the spring or autumn. 4. In winter, the insulation measures will be adopted to lower the temperature in winter and measures shall be taken to protect the biogas digesters. The straw can be piled on the pool or covered with straw and wheat straw to keep warm. At the same time, the straw can be covered and covered with firewood. If there is a condition, a plastic greenhouse or a plastic film can be built on the upper part of the pool body, so the insulation effect is better.
