东华公司入选绿色转型典型案例

Core Viewpoint - The 2025 China Petroleum and Chemical Industry Green High-Quality Development Conference highlighted exemplary cases of comprehensive green transformation, with a focus on sustainable practices in the coal chemical wastewater treatment sector [1] Group 1: Conference Highlights - The conference took place in Guangzhou from October 28 to 29, 2025, recognizing typical cases of green transformation in the industry [1] - China Chemical's Donghua Engineering Technology Co., Ltd. was awarded for its project on "Zero Discharge of Coal Chemical Wastewater and Collaborative Development of Resource Recycling," which serves as a replicable model for the industry [1] Group 2: Key Innovations of the Case - The project emphasizes a comprehensive lifecycle governance system that addresses key challenges in coal chemical wastewater treatment, achieving systematic breakthroughs from source reduction to resource regeneration [1] - Four major innovative highlights were presented: 1. Implementation of lifecycle governance through key technologies such as source resource collaboration, biological enhancement treatment, low-consumption concentration, and salt resource recovery, leading to efficient recovery of water and salt [1] 2. System coupling optimization of "water-energy-waste" technology paths aimed at low-carbon, economical, and stable operations, overcoming high energy consumption and carbon emissions through energy-saving unit processes and process coupling [1] 3. Development of an intelligent control platform with real-time configuration and smart diagnostic models to enhance system monitoring sensitivity and operational efficiency [1] 4. Realization of a resource recycling loop for "wastewater-salt-acid-base" through efficient quality crystallization and precise impurity control, converting recovered salts into industrial-grade products and further into acids and bases, promoting a shift towards resource circular utilization [1]
