Discuss the use and corrosion of concrete sewage tanks and storage tanks

Thread Content

Many large concrete storage tanks are used in industries such as petroleum, chemicals, hydrometallurgy, thermal power generation, and pharmaceuticals; their purpose is to store acidic and alkaline liquids； Neutralization of acids and bases ； Storage of wastewater ； The storage of gypsum slurry and lime slurry in flue gas desulfurization systems, etc. These reservoirs are generally of buried or semi-buried type, in closed, semi-closed, or open outdoor configurations, and most of them are constructed using reinforced concrete. Due to being exposed over long periods to chemicals such as acids and bases, industrial wastewater, industrial pollutants, ultraviolet radiation, as well as wear and erosion caused by moving particles, these storage tanks suffer from various complex forms of corrosion, including acid-base corrosion, atmospheric corrosion, abrasion, stress corrosion cracking, and microbial corrosion caused by bacteria and algae, all of which significantly reduce their service life
