How can we reduce the loss of nitrogen in the npk fertilizer production line
? During the organic fertilizer fermentation process, if the fermentation conditions are not well controlled, the nitrogen in the raw materials will be lost in the form of ammonia. If the nitrogen loss is too large, the fertilizer efficiency of the fermented organic fertilizer will be greatly reduced and the pile will be emitted. The ammonia that comes out can also pollute the air environment, damage the respiratory health of operators, and corrode buildings and equipment.
The following countermeasures can be implemented, and the loss of nitrogen in the fertilizer production line
can be effectively controlled, and the efficiency of the fermented organic fertilizer will not be bad.
1. The use of compost bacteria (organic fertilizer starter) containing nitrogen-fixing bacteria can also effectively reduce the loss of nitrogen.
2. In the process of organic fertilizer fermentation, the turning process conditions must be controlled. One of the main functions of turning the pile is to provide sufficient oxygen inside the compost. This can also reduce the loss of nitrogen.
3. Adsorbents and conditioning agents can be added: such as molecular sieves, silica gel, activated carbon, and basalt, etc., with or without straw and orange peel, etc., have a good nitrogen retention function.
4. Adjust the carbon-nitrogen ratio of the starting materials for fermentation: Generally, the carbon-nitrogen ratio is planted in the range of 25-35, and the best is 30. If the carbon-nitrogen ratio is lower than 20, the total nitrogen of the compost raw materials will easily be ammonia. The form of Qi exudes. For fertilizer granulation, a Double Roller Granulator
5. Adjust the air permeability of the material: Another important reason for the production of ammonia smell during the organic fertilizer fermentation process is that the air permeability of the material is not good. The large reduction in nitrogen is lost in the form of ammonia.
6. Nitrogen loss inhibitors can be added, such as zeolite, superphosphate, and a small amount of manganese sulfate.
