Abstract:Geothermal resource is very rich in Dongying city. Exploitation of geothermal resources has increased very rapidly in recent years. Main exploitation layers of thermal energy storage are Dongying formation and Guantao formation. Its development and utilization are heating bath. Due to imperfect technologies of comprehensive utilization, the irrational exploitation and the tail water of any emissions have caused some negative impacts to local environment. In this paper, based on the current development of geothermal resources and present condition of development and utilization, by using cascade development model, the impact of tail water discharge to local environment has been improved. Some suggestions for geothermal resources protection and environmental governance have been put forward as well.
