The desulfurization wastewater system includes: wastewater treatment system, chemical dosing system, sludge conveying system, bypass system and two-phase common sludge compression system. The chemical dosing system includes: lime slurry supply subsystem, hydrochloric acid supply subsystem, coagulant preparation and slurry supply subsystem, ferric sulfate supply subsystem and organic sulfur TMT15 supply subsystem.
The wastewater generated by the flue gas desulfurization device comes from the overflow of the gypsum cyclone station and is pumped to the wastewater treatment system by the wastewater pump through the wastewater cyclone station. After continuous treatment with chemical dosing, the process steps are as follows:
1. Use calcium hydroxide and lime slurry [Ca(OH)] for alkalization treatment. Through the set pH range, some heavy metals are precipitated in the form of hydroxides
2. By adding organic sulfides, some heavy metals such as potash and mercury are precipitated.
3. By adding flocculants and coagulants, solid precipitates are flocculated in the form of large particle floccules that are easier to settle.

★FAQ

Q. What are the common sewage treatment processes?
A. Common sewage treatment processes include activated sludge method (such as A²/O, oxidation ditch, SBR), biofilm method (such as biofilter, biorotor), membrane bioreactor (MBR), etc. These processes mainly use physical, biological and chemical means to remove organic matter, suspended solids, nitrogen and phosphorus and other pollutants in sewage to achieve standard discharge or water resource reuse.

Q. How is the sludge generated during sewage treatment handled?
A. The sludge generated during sewage treatment needs to be concentrated, dehydrated, stabilized (such as anaerobic digestion) and other treatments to reduce the volume and reduce pollution. The treated sludge can be used as a resource, such as fertilizer, incinerated for power generation, or landfilled. Reasonable disposal of sludge is an important part of ensuring that the entire sewage treatment process meets environmental standards.

Q. Does the sewage treatment plant have a bad smell? How to control the odor pollution?
A. Sewage treatment plants may produce bad smells at water inlets, grit chambers, sludge treatment areas and other places. In order to control the odor pollution, deodorization measures such as sealing facilities, negative pressure collection, chemical washing, biological filters or activated carbon adsorption are usually adopted, and the plant area is reasonably laid out and green belts are set up to reduce the impact on the surrounding environment.
