What are the environmental protection measures for making organic fertilizers

The environmental protection measures in the process of organic fertilizer production mainly include odor control, dust control, fly control, etc. The following are specific measures:

odor control

• Raw material pretreatment: A certain amount of zeolite, peat, superphosphate or crushed wood chips are mixed into the raw materials for organic fertilizer fermentation. These substances can adsorb odorous gases such as ammonia and hydrogen sulfide produced during the fermentation process, thereby reducing their concentration and minimizing the loss of organic raw material nutrients.
• Adsorption treatment: allowing odorous gases to flow through a layer of substances with strong adsorption capacity, utilizing the strong adsorption properties of these substances to remove odorous gases. Activated carbon is a good adsorbent that can effectively treat inorganic and organic substances that make up odorous gases.

dust control

• Closed operation: In processes such as crushing and screening that are prone to generating dust, it should be carried out in a closed fermentation chamber or indoor environment. This can effectively prevent dust leakage and reduce environmental pollution.
• Equipment configuration: Closed containers should be equipped with air collection and particle control equipment, wet scrubbers or fiber filters, etc., to further reduce dust emissions.

Fly control

• Raw material management: Organic raw materials should be directly processed in fermentation facilities or processing equipment upon arrival at the factory to prevent open stacking. A small portion of raw materials that have not been processed in a timely manner should be collected and covered with plastic sheeting to seal them; Raw materials that require temporary storage should be sent to the warehouse or temporary storage area for storage.
• Environmental hygiene: Maintain clean environmental hygiene, take measures from the source, reinforce transportation equipment, and reduce the omission of organic materials such as feces. Once there is any omission, it should be cleaned up in a timely manner.
• Drug prevention and control: When necessary, measures such as spraying can be taken to eliminate flies, prevent them from polluting the environment, and spread diseases and pests.

In summary, environmental protection measures in the production process of organic fertilizers are multifaceted and comprehensive. The implementation of these measures not only helps to reduce environmental pollution, but also improves the quality and safety of organic fertilizers. Therefore, in the production process of organic fertilizers, relevant environmental regulations and standards should be strictly followed, effective environmental measures should be taken to ensure the environmental friendliness and sustainability of the production process.
