How to ferment biogas digesters safely?

(1) It is forbidden to put toxic pesticides, various fungicides and inhibitors that have an impact on the biogas fermentation process into the biogas digester, so as not to destroy the normal fermentation or even stop the biogas production. If this happens, you should clear all the fermentation broth in the pool, rinse it with clean water, and then start again. (2) It is forbidden to put calcium carbide into the pool, so as not to kill the biogas fermentation bacteria in the pool and cause an explosion accident. ③ Some agricultural and sideline products, such as rapeseed cake (oil cake), cottonseed cake, bone meal, calcium superphosphate, etc. , are easy to produce toxic gas-dihydrogen phosphide, so it is not appropriate to enter the pool in large quantities. ④ Strictly prevent surface water (including rainwater and ditch water) and roof water from flowing into the biogas digester, flooding the gas storage chamber, diluting the concentration, lowering the pool temperature and affecting gas production.
