Precautions before and after installation of black film biogas digester
1. Precautions before the installation of the black film biogas digester.
1.Site selection: The black film biogas digester should be selected in a place with leeward and sunny, high groundwater level and suitable soil quality. At the same time, avoid places overgrown with rocks and weeds so as not to affect construction and gas production.
2.Prepare materials: Before installation, prepare the required materials, including black film, sealant, support rods, air ducts, etc. The black film should be made of materials with moderate thickness and reliable quality to ensure the tightness and durability of the digester.
3.Foundation treatment: Before installation, the foundation ground treatment of the digester should be leveled and the foundation should be tamped to avoid sinking or tilting of the digester. At the same time, it is necessary to remove debris and stagnant water on the foundation ground to ensure that the foundation ground is clean and dry.
4.Black film inspection: Before installation, the black film should be carefully inspected to ensure that it is free of breakage, scratches, wrinkles, etc. If there is damage or scratches, the black film should be repaired or replaced in time to avoid affecting the sealing effect.
5.Sealant preparation: Before installation, an appropriate amount of sealant should be prepared to be applied at the black film seam to ensure the sealing effect. At the same time, it is necessary to check the quality and expiration date of the sealant so as not to affect the use effect.
2. Precautions after installation of black film biogas digester.
1.Leak testing: After installation, the digester should be tested for tightness to ensure that there are no leaks. The digester can be tested by aerating or pressurizing, and if a leak is found, the black film should be repaired or replaced in time.
2.Daily maintenance: During use, the biogas digester should be inspected and maintained regularly, including checking whether the black film is damaged or aging, and whether the sealant is intact. At the same time, it is necessary to keep the digester clean and dry to avoid debris and stagnant water from entering the tank.
3.Regular cleaning: The biogas digester should be cleaned regularly, including removing debris, cleaning the air duct, etc. When cleaning up, you should pay attention to safety to avoid accidents.
4.Reasonable feeding: In order to ensure the normal operation of the biogas digester and the gas production effect, reasonable feeding should be carried out. The concentration and temperature should be controlled when feeding, and an appropriate amount of starter culture should be added to improve the gas production. At the same time, it is necessary to pay attention to safety and avoid accidents such as poisoning or **.
5.Precautions: During use, attention should be paid to safety to avoid accidents. At the same time, it is necessary to pay attention to weather changes and geological conditions, so as not to affect the normal operation and service life of the biogas digester.
