4月3日，在兰州石化公司公用工程一部动力水处理区域，化学水处理岗位员工牟瑞紧盯着混合离子交换器正洗排水在线pH计，精细调控着每个“流失点”，将废水重新“请”回生产系统。这一举措，正是该公司推动环保治理由“达标排放”向“价值创造”转型、助力企业提质增效的生动缩影。

On April 3rd, in the power water treatment area of the First Department of General Engineering of Lanzhou Petrochemical Company, chemical water treatment staff Mu Rui closely monitored the online pH meter of the mixed ion exchanger's flushing drainage. He meticulously controlled each "leakage point" and brought the wastewater back into the production system. This measure is a vivid illustration of the company's efforts to transform environmental protection governance from "compliance with standards" to "value creation", and to help the enterprise improve quality and increase efficiency.

兰州石化坚持系统思维，对每一处“流失点”实施精细化管控。源头管控上，通过优化预处理加药、强化过滤器反洗水回收、规范在线仪表长流水管理，年回收废水约20万吨；同时提升反渗透系统运行效率，稳步提高浓水回用率。在供水、空分等环节，精准调控循环水电导、优化排污周期等措施，变“被动排水”为“按需排水”，全年可减少排水数万吨。

Lanzhou Petrochemical adheres to a systematic approach and implements meticulous control over every "leakage point". At the source control level, through optimizing pre-treatment dosing, strengthening the recovery of reverse wash water from filters, and standardizing the management of continuous water flow of online instruments, approximately 200,000 tons of wastewater are recycled annually. At the same time, the operational efficiency of the reverse osmosis system is improved, steadily increasing the reuse rate of concentrated water. In water supply, air separation, and other processes, precise regulation of circulating water conductivity and optimization of the sewage discharge cycle are implemented. This transforms "passive drainage" into "drainage as needed", resulting in a reduction of drainage volume of several hundred thousand tons throughout the year.

在化工净化水区域，兰州石化建立进水预警与分级调控机制，利用缓冲池实现“削峰填谷”，创新实施绿化水回用，全年减少外排水十余万吨。炼油净化水区域以“稳系统、提回用”为主线，优化关键环节运行，保持回用水量高位运行，积极推进雨水收集再利用，将“天上水”变为“系统水”。

In the chemical purification water area, Lanzhou Petrochemical has established an incoming water warning and hierarchical regulation mechanism, using buffer ponds to achieve "peak reduction and valley filling", and innovatively implemented the reuse of green water. As a result, over 100,000 tons of external wastewater were reduced throughout the year. In the refining purification water area, with the main line of "stabilizing the system and increasing reuse", the operation of key links has been optimized, maintaining a high level of return water volume, actively promoting the collection and reuse of rainwater, and transforming "water from the sky" into "system water".

技术升级是兰州石化实现提质增效的核心驱动力。兰州石化通过更换曝气系统、优化臭氧催化氧化工艺，大幅提升化工污水COD去除效率。在废气治理方面，持续推进高浓度废气处理能力提升和低浓度VOCs治理技术升级，实现减排与降本双赢。

Technological upgrading is the core driving force for Lanzhou Petrochemical to achieve quality improvement and efficiency enhancement. Lanzhou Petrochemical has significantly increased the COD removal efficiency of chemical wastewater by replacing the aeration system and optimizing the ozone catalytic oxidation process. In terms of waste gas treatment, it has continuously improved the treatment capacity for high-concentration waste gases and upgraded the technology for low-concentration VOCs control, achieving a win-win situation of emission reduction and cost reduction.

围绕控污减排目标，兰州石化还建立了全过程精细管控机制，将关键指标层层分解，通过动态监测与数据分析优化运行策略，并将成效纳入考核体系，形成管理闭环。从控污减排到提质增效，兰州石化持续深化水资源循环利用，稳步推进绿色低碳示范项目建设。

In line with the goals of pollution control and emission reduction, Lanzhou Petrochemical has established a comprehensive and meticulous control mechanism throughout the process. Key indicators are broken down layer by layer, and operational strategies are optimized through dynamic monitoring and data analysis. The results are incorporated into the assessment system to form a management loop. From pollution control and emission reduction to improving efficiency and effectiveness, Lanzhou Petrochemical has continuously deepened the recycling of water resources and steadily advanced the construction of green and low-carbon demonstration projects.
