| titleOfInvention | Method for reducing arsenic content of biogas slurry |
| abstract | The invention relates to a method for reducing arsenic content of biogas slurry. The method comprises the following steps. Anaerobic fermentation inocula are added and conventional fermentation is carried out in a biogas production system. When the additive amount of inocula in the biogas production system increases to 10-40% of fermented substance dry weight, FeCl2 with a concentration of 0.2-1.0 g/L is added at the same time. The mixture is mixed uniformly and conventional fermentation is carried out. The optimum scheme is that quick-acting carbon source weighing 1-10% of raw material dry weight is added and mixed uniformly and conventional fermentation is carried out. The anaerobic fermentation inocula can be biogas residues of old biogas tanks, or putrid river mud, or fresh pig manure, or mixtures thereof. The quick-acting carbon source can be straws, or vegetable residues, or kitchen garbage, or vinasse, or mixtures thereof. |
