Baijiahaizi Mine Water & Domestic Sewage Comprehensive Utilization EPC Project
Baijiahaizi Coal Mine, a key energy project in the national and regional "14th Five-Year Plan", is situated in Shenshuitai Village, Galuotu Town, Wushen Banner, Ordos, Inner Mongolia. It's among China's largest shaft mines, with an annual output of 15 million tons and a max. underground water inflow of 3,000 m3/h. The EPC project of Baijiahaizi Mine Water & Domestic Sewage Comprehensive Utilization by Jingyu Environment is a demo under the national water-saving policy and a milestone in ultra-large zero-discharge. Given the high salt content in its mine water, Jingyu Environment adopts a process combo of three-stage high-density, pretreatment, UF, RO, NF salt separation, and evaporation crystallization to achieve zero wastewater discharge and resource utilization of sodium oxide and sulfate. This project is vital for preventing water loss and pollution, relieving water shortages, enhancing the ecological environment, and fulfilling water demands for production and daily life.
