[Method for environmental management in paper industry based on pollution control technology simulation]

Area of Science:

• Environmental Science
• Industrial Ecology
• Chemical Engineering

Background:

• Industrial water pollution poses a significant environmental challenge.
• Effective pollutant control and environment management strategies are crucial for sustainable industrial development.
• Technology simulation offers a promising approach for evaluating emission reduction potentials.

Purpose of the Study:

• To develop and apply an Industrial Reduction Potential Analysis and Environment Management (IRPAEM) model.
• To evaluate the reduction potential of industrial water pollutant emissions in China's paper industry.
• To study the application of technology simulation in pollutant control and environment management.

Main Methods:

• Developed an IRPAEM model coupling "material-process-technology-product".
• Integrated bottom-up modeling and scenario analysis.
• Applied the model to China's paper industry for emission reduction assessment.

Main Results:

• Under the CM scenario, substantial reductions in wastewater, COD, and ammonia nitrogen are projected for 2015 and 2020.
• End-treatment is identified as the primary emission reduction method from 2010-2020.
• Structural adjustments become more impactful for emission reduction between 2015-2020.
• Pollution production is expected to reach advanced clean production levels by 2015 and 2020.
• Wastewater and ammonia nitrogen indices are projected to meet emission standards, but COD may not.

Conclusions:

• The IRPAEM model effectively simulates emission reduction potentials and informs environmental management strategies.
• A combination of end-treatment and structural adjustments is necessary for significant pollutant reduction in the paper industry.
• While progress is expected, COD emissions may require further targeted interventions to meet standards.
