神木煤化工反渗透浓水降垢项目投运

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]
