在很多人印象中，钢铁厂意味着轰鸣的机器、高温的炉火和弥漫的烟尘，但在乌鲁木齐的新疆八一钢铁 集团有限公司（以下简称"八钢"），却藏着一个天鹅湖：绿树掩映之间，一池碧水静静流淌，天鹅悠然 划过水面，鸭子成群结队嬉戏。这是八一钢铁文化工业旅游景区的湖景。 钢铁厂与生态园，两个本不相干的词，在八钢实现了美丽的交汇。中青报·中青网记者近日随"砥砺奋进 七十载 天山南北谱华章"采访团走进八钢，亲眼见证了一个重工业企业如何把绿色作为发展的底色，用 科技书写环保答卷。 "这些年，我们不仅在能源环保领域大量投入，而且着眼未来发展积极做好专业人才储备。"八钢总经 理、党委副书记何宇城表示，"以前是高能耗，现在我们是零排放、低碳化。绿色发展，是八钢的未 来。" 作为以钢铁为主题的国家3A级工业旅游景区，八一钢铁文化工业旅游景区每年接待游客数万人。在这 里，绿色是推动钢铁产业转型升级的重要引擎。 这座污水处理厂不仅能将生产废水、生活污水净化至"绿化标准"，还能将其进一步深度处理至饮用水级 别。记者在采访现场饮到了这种深度净化水，味道清甜可口。 天鹅湖中的水是"西域源"处理后的再生水。这水不仅养活了湖中的鱼，也浇灌着厂区内外的绿色植 ...

Core Insights - The article highlights the innovative water management practices of Shenhua Group's coal mines, transforming mine water into a resource for ecological restoration and sustainable development [1][3][5] Group 1: Water Management and Treatment - Shenhua Group has developed a three-stage water treatment process for mine water, which includes primary filtration, ultra-filtration, and reverse osmosis, achieving a fluoride content reduction to 0.8 mg/L [3] - The integrated system processes 32,000 cubic meters of mine water daily, ensuring water quality exceeds surface water Class III standards, thus achieving zero wastewater discharge [3][4] - The company has implemented a comprehensive water resource management system that includes monthly performance assessments linked to water usage targets [4] Group 2: Ecological Impact and Transformation - The treated mine water is utilized for irrigation in subsided areas, transforming 300 acres of previously collapsed land into tiered ecological wetlands, significantly improving vegetation coverage to 64% [3][5] - The annual reuse of over 5 million cubic meters of mine water meets the ecological irrigation needs of the Halaogou subsidence area, increasing plant survival rates from 90% to 95% [3][5] - The integration of technology and ecological principles in water management demonstrates a successful model for sustainable development in mining regions [7]

Core Insights - The project by Shenmu Coal Chemical Energy Company focuses on the implementation of reverse osmosis technology to treat difficult wastewater, converting 900 tons of concentrated water into reusable water daily, saving 1,800 yuan in water fees per day and reducing wastewater discharge by 270,000 tons annually [1][2] Group 1 - The project utilizes a "pre-treatment + dual-stage reverse osmosis" closed-loop treatment process, achieving a total dissolved solids (TDS) level of ≤100 mg/L and conductivity of ≤300 μS/cm, effectively meeting industrial water needs for cooling and desulfurization [1] - The project team leveraged existing infrastructure, focusing investments on key technology upgrades, resulting in a 60% reduction in equipment procurement costs through a "reuse + upgrade" model [1] - The newly implemented ultrafiltration and dual-stage reverse osmosis systems are designed for modularity and fully automated operation via a DCS control system, minimizing hidden costs [1] Group 2 - The treated water is supplied directly to four auxiliary cooling units and secondary cooling island spray systems, leading to an annual cost savings of 1.46 million yuan and effectively controlling the water level in the mine's first clean water pool, mitigating safety and environmental risks [2] - The modification has resulted in a 60% reduction in concentrated water discharge, laying the groundwork for future zero-discharge wastewater projects [2]

Core Viewpoint - The company Huayu has been recognized as the "Water Efficiency Leader" in the coal-to-methanol industry for 2024 by the China Fertilizer Industry Association, marking its fourth consecutive year of receiving this honor [1] Group 1: Water Management Practices - Since its inception, the company has prioritized water conservation management, achieving a water intake of 6.98 cubic meters per ton of product and a water reuse rate exceeding 98% [1] - The company employs advanced coal chemical technologies to control water usage from the source, including steam condensate recovery and high-efficiency cooling systems [2] - A comprehensive water management system has been established, including a water consumption plan and monitoring systems to prevent leaks and optimize water use [3] Group 2: Wastewater Treatment and Zero Discharge - The company has implemented advanced technologies for zero wastewater discharge, resulting in a wastewater discharge of only 1.04 cubic meters per ton of product for 2024, with significant improvements in water reuse and efficiency [4] - Investments of 134 million yuan have been made in wastewater treatment projects, achieving a 43.9% reduction in wastewater discharge, a 63.4% reduction in COD, and a 49.2% reduction in ammonia nitrogen [4] - The company has established a scientific water conservation planning and responsibility system to enhance deep wastewater recycling and smart manufacturing [4]
