Daily maintenance and upkeep of biogas biological desulfurization system

Aug 07, 2025

The biogas biological desulfurization system is one of the important equipment in biogas engineering. Its main function is to remove hydrogen sulfide gas from biogas and meet the gas requirements of the back-end. The daily maintenance and upkeep of the biogas biological desulfurization system are key to ensuring its efficient operation and extending its service life. The following are the main maintenance and upkeep measures:
1、 Regular inspection
Gas composition monitoring: Regularly detect the concentration of hydrogen sulfide in biogas to ensure that the desulfurization effect meets the standard.
PH monitoring: Biological desulfurization relies on microbial activity and requires regular checks of the pH value inside the reactor.
Temperature monitoring: Maintain appropriate temperature to ensure microbial activity.
Nutrient solution inspection: Regularly check the remaining amount of nutrient solution, add nutrients to the reactor, and ensure the normal growth of microorganisms.
2、 Equipment maintenance
Reactor cleaning: Regularly clean the sediment and impurities inside the reactor to maintain the cleanliness of the equipment and prevent blockages.
Pump and pipeline inspection: Regularly inspect pumps, pipelines, and valves to ensure no leaks or blockages.
Electrical component inspection: Regularly inspect the electrical components, wires, etc. of the equipment for aging or damage, ensuring the electrical safety and normal operation of the equipment.
Filter replacement: Regularly replace or clean the gas filter to prevent blockage and affect gas flow.
Comprehensive inspection: Regularly conduct comprehensive inspections of equipment and replace or repair vulnerable parts;
3、 Security measures
Gas leakage detection: Regularly check the sealing of the system to prevent biogas leakage.
Pressure testing: Regularly conduct pressure testing on equipment to ensure stable pressure and safe operation.
Emergency plan: Develop and regularly practice emergency plans to ensure quick handling of unexpected situations.
4、 Record and Report
Operation record: Detailed record of system operating parameters (such as gas composition, pH value, temperature, etc.).
Maintenance records: Record the time, content, and issues discovered during each maintenance.
Regular reports: Generate regular operation and maintenance reports, analyze the system's operating status, and provide improvement suggestions.
5、 Training and Personnel Management
Operation training: Regularly train operators to ensure familiarity with system operation and maintenance.
Responsibility division: Clearly define maintenance responsibilities and ensure that each task is assigned to a dedicated person.
Through the above measures, the biogas biological desulfurization system can be effectively maintained to ensure its long-term stable operation.
