Abstract: This paper herein introduced the detailed designing of mine water advanced treatment of Zhong Tian He Chuang Co., Ltd., as well as the investment budget. The economy and technology of two different technological processes were compared. The treatment process, treatment equipment and building were introduced. The effect of investment budget and running cost on economic benefit was presented. The key points of process design were concluded. Result shows that effective integration of the processes of desalination, subsequent concentrations and evaporative crystallization is important to the integral process chain. Conclusively, this paper can provide experience and reference for emissions-free and resource utilization techniques of mine water and coal chemical wastewater treatment.
