Operation Process of HDPE Geomembrane Biogas Digesters

For the pig farmers, the pig manure can be arbitrarily discharged to the nearby Xiaogou River, but now it is not working, the environmental protection should reach the standard, forcing you to consider the whole process of production and discharge. The construction and use of the biogas digesters is the last link in the entire environmental protection standard. How to save money and maximize the income of biogas is a problem that many people think about. Now we have a simple analysis of the construction and operation of black membrane biogas digesters, hoping to be beneficial to the friends who raise pigs.

Cement biogas digesters are common many years ago, and the black membrane (high quality LDPE geomembrane) biogas digesters are the most widely seen. Cement biogas digesters are cemented with cement after digging wells. They are relatively firm and have few damages, but they are expensive and disposable. They are easy to leak with the extension of service life. The black membrane biogas digester is simple to construct and low in cost. Generally, it is only necessary to cover the bottom of the digging pool, and the cover film is placed on the top, and the manure of the pig farm can be continuously discharged.

How long does it take to ferment after the sewage comes in? Temperature is also a factor that affects the ability of anaerobic organisms. Generally, if the temperature is right, the wastewater and waste residue from 20-30 days of biogas fermentation can be discharged. If the temperature is very low, it may be To be extended. If the waste residue is to be cleaned, it should be ventilated before entering the pool to discharge the remaining biogas, otherwise, it will easily cause poisoning.
