To ensure that the production process of the organic fertilizer production line meets environmental protection requirements, the following aspects can be considered:

Waste gas treatment: Waste gas generated in the fermentation, drying and other sections. In key links of the production line, such as crushing and screening, gas collection hoods are set up to collect the waste gas and treat it uniformly.

2. Wastewater treatment: The factory area should implement rainwater and sewage separation to ensure that wastewater is effectively collected and treated. Biological treatment, chemical treatment and other processes are adopted to conduct advanced treatment on wastewater to meet discharge standards or for resource utilization.

3. Solid waste treatment: Classify, collect, store and dispose of solid waste to prevent environmental pollution. Recyclable waste should be utilized for resource utilization. For instance, organic waste can be used for composting or biomass energy production.

4. Energy consumption management: Select highly efficient and energy-saving organic fertilizer equipment to reduce energy consumption during the production process. Encourage the use of clean energy such as solar and wind power to reduce reliance on traditional energy sources.

5. Environmental protection facilities: The factory area should be equipped with necessary environmental protection facilities, such as waste gas treatment facilities, waste water treatment facilities, noise control facilities, etc., to ensure that pollutants during the production process are effectively controlled.

6. Site selection and layout: Choose a location far from residential areas to avoid any impact on residents' lives. At the same time, the convenience of raw material transportation should be taken into consideration, and it should be as close as possible to the raw material supply area. Ensure that the production area is separated from the office and living areas to avoid cross-contamination.

Through the above measures, it can be ensured that the production process of the organic fertilizer production line meets environmental protection requirements, reduces the impact on the environment, and at the same time enhances the social image and market competitiveness of the enterprise.
