Limestone gypsum wet desulfurization technology can effectively remove sulfur dioxide from flue gas, control the concentration of dust particles in mud, and ensure material balance of desulfurization equipment. In this case, it is necessary to discharge a certain amount of wastewater to promote the discharge of fly ash. Desulfurization wastewater contains a certain amount of sulfites, sulfates, and heavy metals, which are classified as a type of pollutant in the standard and seriously pollute the ecological environment. In this situation, it is necessary to actively optimize the zero discharge treatment process of desulfurization wastewater from coal-fired power plants and adhere to the stable and sustainable development of the ecological environment.

Coal fired power plants are the pillar industry of China's modern economic construction, which can largely meet the daily power supply needs of social groups and play an important role in promoting national economic growth. Under the concept of sustainable development, the policy is constantly being promoted, and the awareness of social groups is constantly improving. The government attaches great importance to the discharge of desulfurization wastewater from coal-fired power plants. To further strengthen ecological and environmental protection, actively optimize the zero discharge treatment process of desulfurization wastewater from coal-fired power plants, and improve the ecological and economic benefits of coal-fired power plants.

The production practice of coal-fired power plants has shown that the high salt content of desulfurization wastewater is closely related to the practical power supply demand of coal-fired power plants. With the increase of electricity supply and demand in coal-fired power plants, the salt content of desulfurization wastewater also increases.

In terms of the practical discharge of desulfurization wastewater from coal-fired power plants, after the absorption of coal and flue gas, the composition of desulfurization wastewater changes significantly, especially the composition of sodium ions, calcium ions, sulfate ions, and heavy metal ions. With the continuous operation of power plant equipment, the quality of desulfurization wastewater has undergone significant changes, causing severe pollution to water resources..

Nowadays, the limestone gypsum wet desulfurization technology is mainly applied to the treatment of desulfurization wastewater in coal-fired power plants. However, in the practical operation of coal-fired power plants, the large amount of suspended solids in desulfurization wastewater severely restricts the safe operation of coal-fired power plants.
