Environmental impact and clean utilization approach of middle-deep geothermal water development: A case study of Guanzhong area, Shaanxi Province

Taking Guanzhong area of Shaanxi Province as an example, the influences of development and utilization of middle-deep geothermal water on water, soil, biological, thermal and atmospheric environment are systematically summarized according to the regional environmental survey data of typical middle-deep geothermal resources utilization. Based on typical cases, the paper focuses on the role of middle-deep geothermal water recharge technology and geothermal tailwater pollutant treatment technology in solving environmental pollution caused by geothermal development, and puts forward suggestions for ways and policy of clean utilization of middle-deep geothermal water, so as to provide scientific basis for the sustainable development and utilization of geothermal resources in the future.
