Due to factors such as temperature and chemical reaction, the pH value detection often cannot accurately reflect the chemical stability of water. In the water treatment process, scaling and corrosion factors are more, but the chemical stability is mainly determined by the balance relation among heavy calcium carbonate, calcium carbonate and carbon dioxide in water due to the contents of Ca2+, HCO3-, CO 32-and CO2 and the salt solubility thereof, calcium carbonate precipitation may be generated when the content of free carbon dioxide in water is low, and cathode hydrogen depolarization corrosion caused by carbon dioxide is generated when the content of free carbon dioxide in water exceeds the balance.
At present, no detection instrument for the stability of water quality exists. This is completely different from the water quality stability index calculated by the empirical formula, which is often more ideal, so the actual use factor is the root cause of the deviation of the result of the water quality stability index from the actual one, which results in poor reliability of practical application, and the water quality stability characteristics of the water quality of various water samples (such as lime-treated effluent, industrial water, circulating water, etc.) in industries such as industry and thermal power generation cannot be accurately and conveniently determined.
