How is the water treated after desulfurization in the desulfurization tower?
Summary： The water from the desulfurization tower after desulfurization contains high concentrations of suspended solids, high levels of chloride ions, high salinity, and heavy metals.

The water from the desulfurization tower after desulfurization contains high concentrations of suspended solids, high chlorides, high salinity, and heavy metals. If discharged directly, it can cause serious pollution to the environment, so it must be properly treated. Below is a brief introduction to the treatment process of desulfurization wastewater:
1. Pre-treatment: Remove large particle impurities and suspended solids from the wastewater through facilities such as screens and sedimentation tanks, providing conditions for subsequent treatment.
2. Neutralization treatment: Add an appropriate amount of lime slurry or other neutralizing agents to the wastewater to adjust the pH value, promoting some heavy metal ions to precipitate out in the form of hydroxides.
3. Heavy metal removal: Add heavy metal precipitating agents to react with heavy metal ions in the wastewater to form insoluble precipitates, which are then removed through sedimentation, filtration, and other methods.
4. Advanced treatment: Use technologies such as sand filtration, carbon filtration, and membrane separation (such as reverse osmosis and nanofiltration) to further remove dissolved solids and organic matter from the wastewater.
5. Disinfection treatment: Eliminate pathogenic microorganisms in the wastewater to ensure the safety of the effluent water quality.
6. Discharge or reuse: If the treated wastewater meets discharge standards, it can be discharged directly; if the water quality is good, reuse can also be considered.
Through the above treatment process, harmful substances in the desulfurization wastewater are effectively removed, achieving either standard discharge or safe reuse of the wastewater.
