依托大气综合调度系统，南京为每一个储罐建立了"数字户籍"：类型、物料、浮盘结构、密封等 级、治理设施等信息一应录入，监管从"盲人摸象"走向"精准画像"。在此基础上，市生态环境部门坚 持"一罐一策"，指导企业科学谋划治理项目，针对周转量大、物料真实蒸气压高、涉异味物质的重点储 罐，分时、分类、分批次开展整治。 储罐会"呼吸"，关键在"鼻子"——呼吸阀。中国石化扬子石油化工有限公司安环部部长张伟军打了 个比方："传统呼吸阀就像没关紧的窗户，泄漏量大。而我们引进的低泄漏呼吸阀，泄漏量从0.4立方米/ 小时降至0.003立方米/小时，相当于把窗户关严了。"这不仅大幅减少VOCs排放，也让企业从源头上减 少物料损耗。 "呼吸"之间，藏着减排大文章。近日，生态环境部《生态环境工作简报》专题刊登《VOCs全流程 治理深入推进 各地各行业实践亮点频出（五）——江苏南京储罐深度治理典型案例》，将南京在挥发 性有机物（VOCs）储罐治理方面的探索与实践，作为典型经验向全国推广。这份被生态环境部点赞 的"南京方案"，不仅为大气治理提供了可复制路径，更在看不见的"呼吸"里，实现看得见的减排实效。 走进南京最大的化工园区——南京江北新 ...

Core Viewpoint - The reduction of VOCs (volatile organic compounds) is a critical constraint for improving air quality, and grassroots environmental work must implement practical measures to address the challenges in VOCs governance as the "14th Five-Year Plan" approaches its conclusion [1][3]. Group 1: Challenges in VOCs Governance - The grassroots VOCs governance faces three main difficulties: 1. Difficulty in promoting source substitution due to high cost pressures and weak technical adaptability, leading many enterprises to adopt a wait-and-see attitude [1]. 2. Gaps in process control, with significant issues related to unorganized emissions from storage tanks and pipeline leaks, resulting in regulatory blind spots [1]. 3. Poor effectiveness of end-of-pipe treatment, with many enterprises lacking the ability to select and manage effective VOCs treatment technologies [1]. Group 2: Solutions for VOCs Governance - To address these challenges, a systematic governance approach is recommended, including: 1. Establishing three lists: a target gap list to quantify emission reduction needs by industry and enterprise, a rectification task list with clear deadlines and standards, and a responsibility implementation list to ensure accountability [2]. 2. Engineering reduction strategies should prioritize low-cost, quick-effect solutions tailored to specific industries, such as using "adsorption + combustion" for low-concentration waste gas in furniture and printing industries [2]. 3. Structural reduction should be guided by policies and market forces, with government projects leading by example in using low-VOCs materials and providing incentives for compliant enterprises [3]. Group 3: Future Directions - The next four months are crucial for achieving the goals of the "14th Five-Year Plan," requiring precise measures to ensure timely completion and the establishment of long-term mechanisms for VOCs governance [3].

Core Viewpoint - Guangdong Kangyuan Environmental Protection Equipment Co., Ltd. has successfully developed the "Intelligent and Efficient Composite Biological Filter Bed Technology," overcoming traditional VOCs treatment technology limitations and demonstrating significant ecological and economic benefits across various industries [1] Technology Innovation - The traditional VOCs treatment technologies face issues such as low efficiency, high energy consumption, and secondary pollution. After five years of research, Kangyuan's team achieved breakthroughs in three areas: biological degradation, intelligent control, and material processes [3] - In biological degradation, a high-adaptability composite microbial community was cultivated, achieving a VOCs removal rate consistently above 90%. Compared to traditional methods, microbial activity increased by 50%, and removal efficiency improved from 30% to over 90%, with shock load resistance enhanced by 2.3 times [3] - The intelligent monitoring system integrates IoT sensing, big data analysis, and AI algorithms, allowing real-time collection of 12 key parameters. This innovation reduced energy consumption by 35% compared to traditional methods, while maintaining treatment efficiency fluctuations within ±2% [3] Material and Process - The composite filler developed by the team has a specific surface area of 1800 m²/m³ and a porosity of 85%. The gas retention time is extended to 1.8 times that of traditional technologies, leading to a 30% reduction in microbial film formation time and a decrease in system startup time from 15 days to 10 days [4] Multi-Dimensional Advantages - The technology avoids explosion risks associated with RTO/RCO technologies, achieving an explosion-proof rating of ExdⅡBT4. Operating costs are reduced by over 70% compared to activated carbon adsorption, with a filler lifespan exceeding 8 years and a 70% reduction in maintenance frequency [6] - The process generates no secondary pollution, with degradation products primarily being CO2 and H2O. Noise levels are kept below 65 dB(A), and overall carbon emissions are reduced by 82% compared to combustion methods [6] - The remote monitoring platform allows for 24/7 unattended operation, with a fault self-diagnosis accuracy of 95% and a maintenance response time of two hours. The introduction of a big data prediction model enables a 72-hour advance prediction of filler layer status changes, reducing user maintenance costs by 70% [6] Application Practice - The technology has shown significant results across various industries. In the printed circuit board industry, it effectively addressed complex benzene pollution, maintaining VOCs emissions below 10 mg/m³ and saving annual operating costs of 6.78 million yuan. In the lithium battery industry, a specialized microbial combination achieved a treatment efficiency of 93.5% for NMP recovery tail gas [8] - The technology has standardized modular designs, with a single system capable of handling 5000 m³/h to 100,000 m³/h. As of last year, 23 engineering cases have been implemented across 8 sub-industries, with an online equipment rate of 98.7% [9] - The project has received high praise from experts for its three major innovations: the introduction of AI predictive control technology into biological filter systems, the development of composite fillers with both physical adsorption and biological affinity, and the establishment of a cross-industry VOCs characteristic database. The technology has been granted 3 invention patents and 13 utility model patents, forming a complete technical standard system [9]
