According to appendix c of GB11615-89, the hot water of three thermal reservoirs in the work area is evaluated. See table 7- 1 for the evaluation criteria and measured values of each thermal storage.
As can be seen from the comparison table:
1) The contents of strontium, bromine and radium in the underground hot water of Guantao Formation reach the concentration of named mineral water, which are named strontium water, bromine water and radium water respectively; The contents of iodine, manganese, metaboric acid and metasilicic acid reach the mineral water concentration; The fluorine content reaches the medical value concentration.
2) The contents of bromine, strontium and barium in the underground hot water of Dongying Formation reach the concentration of named mineral water, which are named bromine water, strontium water and barium water respectively; The contents of lithium, beryllium and metasilicic acid reach the mineral water concentration; The content of metaboric acid reaches the concentration with medicinal value.
3) The contents of fluorine, metasilicic acid, strontium and iron in Cambrian-Ordovician underground hot water reach the concentration of named mineral water, which are named fluorine water, silicon water, strontium water and molten iron respectively; Manganese content reaches mineral water concentration.
It can be seen that the underground hot water in the three thermal reservoirs in the work area has high medical value and can be used as bathing and recuperation water or medical care under the guidance of doctors.
Bromine is a sedative; Boron can prevent osteomalacia and participate in human endocrine system; Silicon has a good function of strengthening bones, softening blood vessel elasticity, preventing human aging and cleaning and protecting skin and mucosa; Strontium can play the role of calcium in human body; Lithium can regulate the central nervous system and calm the mood, and can be used to treat kidney calculi, gout and rheumatism.
From the above analysis, it can be seen that the hot mineral water on the third floor of the working area has a good regulating effect on human functions, can strengthen metabolism, promote blood circulation, and can play a health care role in cardiovascular diseases, autonomic nervous dysfunction, rheumatism and other diseases.

Note: Except for radium (10- 1 1g/L) and radon (Bq/L), all other units are mg/L. ..
2. Fishery water quality evaluation
The hot water temperatures of the three hot reservoirs in this area are all higher than the suitable temperature for fish growth, and the F- content is all higher than 1.3mg/L, which exceeds the provisions of the Fishery Water Quality Standard (TJ35-79). Generally, it is not suitable for fishery water, but it can be properly mixed with low fluorine cold water to raise the temperature of cold water to raise fish for overwintering and raise tropical fish such as tilapia.
3. Industrial water quality evaluation
The industrial water here refers to the production water of various enterprises. It can be seen that the contents of chloride, sulfate, iron ion, salinity and other components in the underground hot water of the three thermal storage areas in the area are high, which is not suitable for industrial water such as paper making, textile, printing and dyeing, tanning, wine making, sugar making and construction. Because of its high temperature, underground hot water can be used for industrial heating and heating.
4. Agricultural water quality evaluation
The groundwater temperature of the three thermal reservoirs in the area is above 50℃, the salinity exceeds 1.4g/L, and the highest is 20mg/L. The chemical composition of Cl- and Cl- exceeds the GB 5085-92 standard, which is alkaline water with high water temperature and is not suitable for agricultural irrigation.
