Zero-Discharge Treatment Process Of Desulfurization Wastewater From Coal-Fired Power Plant

Desulfurization wastewater zero discharge process is aimed at thermal power plant desulfurization wastewater characteristics, through the softening, MVR evaporation, crystallization and other technical means to achieve high salinity desulfurization wastewater zero emission requirements, and ultimately see the formation of pure reusable distilled water and crystalline salt.                                          

 Desulfurization wastewater first into the pre-clear pool, to clarify the sediment, reducing raw water turbidity. The precipitate is discharged to the sedimentation concentrate tank and the supernatant enters the triple tank reactor. The contents of Mg2 +, Ca2 + and heavy metal ions in the reaction wastewater were Ca (OH) 2, Na2CO3 and flocculant. The desulfurization wastewater after the reaction flows into the clarification tank, and the flocs in the wastewater are precipitated to the bottom of the tank and discharged to the sedimentation and concentration tank. The supernatant flows into the middle pool and is filtered through the multi-media to enter the clean water tank and the pH The The sludge slurry is further concentrated in the sedimentation and concentration tank, and the sludge is separated into the sludge dewatering machine. After the dehydration, the sludge is transported to the off-site treatment. The sewage is recirculated through the buffer pool.

Zero - Depth Treatment Process of Desulfurization Wastewater

MVR is "mechanical vapor recompression" in English abbreviation (Mechanical Vapor Recompression). The basic principle is that the secondary steam produced during the evaporation process is mechanically recompressed, the secondary steam temperature, the pressure increase, the enthalpy increase, and then into the heat exchanger condensation, the secondary steam latent heat is fully utilized.
