What is the filling of the biogas tank?
3, adding the straw and grass excessive raw materials (floating batch digesters no straw raw materials), should also add lime water and inoculum, prevent excessive acid acidosis. Acidosis occurs in the fermentation process, the feed is sometimes caused by too much. A general upflow float a 10 m3 cover digesters, daily feeding amount of not more than 12 pigs (or 4 cows) stool volume day; dung and hydraulic biogas daily feed control in 6 pigs as well.4, to prevent alkali poisoning. Alkali poisoning generally occurs in the human nature of adding too much alkali, such as lime water, so that the pH value of more than 8.5 of the feed liquid, then methane fermentation is inhibited5, to prevent ammonia poisoning. When adding the raw material in the pool of nitrogen content is too high, or fermented liquid concentration is too large it is easy to occur, therefore in the fermentation process should pay attention to the high nitrogen materials (pig, human, chicken manure) and low nitrogen content of raw materials (cattle, sheep, horse manure) at the same time phase collocation, normal fermentation, fermentation to maintain the suitable concentration, and regularly discharging slag, the fermentation liquid ammonia accumulation reduced, so as to ensure normal fermentation.
And ban the use of calcium carbide, various organic toxic pesticides, fungicides, antibiotics, just spray pesticide crop stems and leaves, fresh sterile plants can make all kinds of livestock manure; soil pesticide, such as garlic, peach leaves, 100, skin soap sub tender fruit and nux vomica fruit; heavy metal compounds, such as salts. Such as electroplating water into the digester. This case should be tank fermentation liquid all out of the net, the pool cleaning after re feeding started.
Problems should be paid attention to in the process of biogas fermentationThe essence of biogas fermentation is the process of microbial life, and the life process of microorganism is influenced and restricted by various factors. Therefore, the following points must be paid attention to in the process of operation
