Desulfurization wastewater treatment
Desulfurization wastewater quality characteristics
The quality of desulfurization wastewater from FGD (limestone-gypsum wet flue gas desulfurization system) device is related to various factors such as desulfurization process, flue gas composition, fly ash and adsorbent. Its main characteristics are: weakly acidic; high suspended solids; Contains Hg, Pb
and other heavy metal ions, many of which are the first category of pollutants that require strict control in national environmental protection standards. Moreover, during the continuous circulation of the slurry, heavy metal elements and Cl- will be enriched. On the one hand, it will accelerate the corrosion of the desulfurization equipment, and on the other hand, it will affect the quality of gypsum. The desulfurization system needs to build a desulfurization wastewater treatment system to process the desulfurization wastewater. Emission standards will be met later. The main items exceeding the standard of desulfurization wastewater are suspended solids, pH value, heavy metal ions, fluoride, etc. Our company has developed an integrated desulfurization wastewater treatment equipment based on the original triple box treatment.
Working principle of integrated processing equipment
The integrated treatment device integrates cyclone sedimentation and shallow concentration technology. The integrated design treatment load has a maximum SS content of about 15%, a high sludge concentration, and a sludge discharge concentration of more than 25%. The entire operation process only requires the addition of solid preparations, and the effluent quality is excellent. The sludge can be directly sent to the vacuum belt conveyor for dehydration and external transportation, without the need to set up a separate sludge dehydration system.
