Management methods of black film digesters in different seasons
The black membrane digester is an efficient and environmentally friendly biogas fermentation plant, which is widely used in waste treatment and energy production in rural and urban areas. However, due to seasonal changes, microbial activity, fermentation temperature, and humidity in the digester are affected, so it is necessary to manage them accordingly depending on the season.
Spring management. Spring is the start-up season of the black film digester, and the gas production will gradually increase due to the gradual increase in temperature and the gradual increase in microbial activity. At this point, you need to do the following:
1.Timely cleaning: Spring is the season for the growth of various plants, and it is also the peak season for livestock and poultry breeding, and the feed port of the black film biogas digester is easy to be blocked. Therefore, it is necessary to clean up the debris in the feed port and the pool in time to ensure the normal operation of the biogas digester.
2.Appropriate amount of feeding: The temperature gradually rises in spring, and in order to ensure the normal fermentation of the biogas digester, it is necessary to increase the amount of feeding appropriately. However, be careful not to overdosing the material, so as not to affect the fermentation effect.
3.Observe the barometer: When the temperature rises in spring, the biogas production will also increase, so it is necessary to observe the barometer and remove excess biogas in time to avoid accidents.
Summer management. When the temperature is high in summer, the fermentation temperature in the black film digester will also increase, which can easily lead to abnormal fermentation. At this point, you need to do the following:
1.Control the fermentation temperature: The temperature is high in summer, and the fermentation temperature in the black film biogas digester is easy to rise. If the temperature is too high, it will affect the activity of microorganisms and cause abnormal fermentation. Therefore, it is necessary to control the fermentation temperature, which can be reduced by adding water to adjust the concentration of the fermentation broth.
2.Increase the frequency of feeding: In summer, the temperature is high, the fermentation rate in the black film digester will be accelerated, and the gas production will also increase. In order to maintain the normal operation of the digester, it is necessary to increase the frequency of feeder changes and remove the excess fermentation broth in time.
3.Do a good job of heat stroke prevention and cooling: In summer, the temperature around the black film biogas digester will also rise, which will affect the normal operation of the biogas digester. Therefore, it is necessary to do a good job of preventing heat stroke and cooling, and you can plant some shade plants or set up shade nets around the digester.
Autumn management. In autumn, when the temperature gradually decreases, the fermentation rate in the black film digester slows down. At this point, you need to do the following:
1.Control the dosage: In autumn, the temperature gradually decreases, and the fermentation rate in the black film digester will slow down. In order to maintain the normal operation of the biogas digester, it is necessary to control the amount of feeding and not overfeeding.
2.Proper stirring: When the temperature decreases in autumn, the fermentation broth in the black film biogas digester is easy to stratify, which affects the fermentation effect. Therefore, the fermentation broth needs to be stirred properly so that it is evenly mixed.
3.Do a good job of insulation: In autumn, the temperature gradually decreases, and the temperature around the black membrane digester also decreases. In order to maintain the normal operation of the biogas digester, it is necessary to do a good job of thermal insulation, which can be covered with insulation materials or set up insulation sheds around the biogas digester.
Winter management. In winter, when the temperature is low, the fermentation temperature in the black film digester will also decrease, which can easily lead to abnormal fermentation. At this point, you need to do the following:
1.Control the fermentation temperature: The temperature is low in winter, and the fermentation temperature in the black film biogas digester is easy to decrease. If the temperature is too low, it will affect the activity of microorganisms and cause abnormal fermentation. Therefore, it is necessary to control the fermentation temperature, which can be increased by heating.
2.Reduced dosage: In winter, when temperatures are low, fermentation in the black membrane digester slows down. In order to keep the digester up and running, the amount of feed needs to be reduced. However, be careful not to reduce the amount of feed excessively, so as not to affect the fermentation effect.
3.Protect against the cold: In winter, when temperatures are low, the temperature around the black membrane digester will also decrease. In order to keep the digester running properly.
