塔罐林立、管廊交错，走进陕西延长石油集团中煤榆林能源化工股份有限公司，一幅现代能源化工图景 跃然眼前。"我们建成国内领先的工业废水'近零排放'系统，通过'污水处理装置+回用水装置+再生水 厂'的三级工艺体系，将生产废水、生活污水乃至厂区雨水处理后回收再利用，实现了废水近零排 放。"该企业公用工程中心主管张小娟介绍。 政企携手共谋绿色发展之路。近年来，陕西榆林紧扣黄河流域生态保护和高质量发展这一基准线，一方 面从前端引导能源产业向高端化、精细化和多元化转型升级；另一方面，从产业尾端发力，通过政策创 新、技术攻坚和全链利用，以工业固废资源化利用为突破口，将"黑色包袱"转化为"绿色财富"，工业固 废综合利用率从2020年的28%跃升至2024年的53%，并计划"十四五"末突破60%。 2023年以来，榆林连续将工业固废管理纳入生态环境保护攻坚行动，将固废利用纳入重点产业链和"五 大攻坚战"。通过财政奖补、税收支持、简化审批等政策组合拳，新建22个示范项目，新增年处理能力 2190万吨，对370家重点产废企业和165家利用处置企业实施数字化监管，并开展"清废行动"。 此外，榆林还联合科研高校制定煤基固废用于盐碱地、沙 ...

Core Viewpoint - The article emphasizes the necessity for chemical companies to implement energy-saving and carbon-reduction actions in response to the "2024-2025 Energy Saving and Carbon Reduction Action Plan," highlighting New Yangfeng's innovative strategies to achieve these goals. Group 1: Technological Innovation - New Yangfeng has invested 1.73 billion yuan in upgrading its ammonia synthesis plant by introducing advanced water-coal slurry gasification technology, which fundamentally changes the traditional high-energy consumption model of ammonia synthesis. After the project launch, the electricity consumption per ton of ammonia decreased from 1,650 kWh to 400 kWh, while production capacity increased threefold, achieving a breakthrough of "increased production without increased carbon" [1]. Group 2: Resource Reutilization - New Yangfeng has innovatively utilized phosphogypsum, a byproduct of the phosphorus chemical industry, by transforming it into various applications such as roadbed materials and building gypsum boards, which replace traditional high-carbon footprint materials. This approach not only mitigates the environmental risks associated with phosphogypsum storage but also contributes to indirect carbon reduction [2]. Group 3: Digital Empowerment - The company emphasizes the importance of digitalization in accurately calculating and controlling carbon emissions. By developing self-control technology in the sulfuric acid roasting process, New Yangfeng has optimized production parameters, reducing temperature fluctuations from ±15°C to ±2.5°C. This enhancement leads to more efficient raw material combustion, reducing sulfur dioxide emissions and lowering raw material and energy consumption [3].

Core Viewpoint - The article discusses the challenges and solutions related to the "second number renewal" service, which aims to provide users with a "clean" mobile number free from previous ownership issues, highlighting the need for better coordination between telecom operators and internet platforms [5][12][14]. Group 1: User Experience and Issues - Many users face difficulties when trying to register new mobile numbers, as these numbers may have been previously active and linked to other accounts, leading to a "digital identity crisis" [3][5]. - The Ministry of Industry and Information Technology (MIIT) reported that by May 2025, the total number of mobile phone users in China is expected to reach 1.807 billion, intensifying the competition for number resources and prompting operators to recycle idle numbers [4]. - The "second number renewal" service, launched in May, allows users to unlink historical internet accounts from their new numbers, covering over 200 mainstream applications [5][12]. Group 2: Operational Challenges - The current "renewal" service primarily involves a one-way request from operators to internet platforms, leading to a lack of transparency and understanding of the processing results for users [7][9]. - Issues such as unstandardized processes and data interoperability hinder the effectiveness of the "second number renewal" service, raising questions about accountability among telecom operators and internet platforms [8][9]. Group 3: Recommendations for Improvement - Telecom operators should establish a rapid response mechanism to enhance service efficiency and transparency, ensuring users can track the progress of their requests [10][11]. - Internet platforms are encouraged to take responsibility for timely responses and efficient processing of unlinking requests, improving communication with telecom operators to streamline the process [11][12]. - Users should be empowered to authorize operators and platforms to handle unlinking matters, creating clear boundaries of responsibility to protect data and ensure compliance [12][13].
