The high solid content liquid causes the clogging and even paralysis of the desulfurization waste water treatment system. Desulfurized wastewater sludge is considered to be a hazardous solid waste, resulting in significant disposal costs each year.
Meanwhile, high-chlorine wastewater such as desulfurization wastewater and the like must be evaporated to dryness for treatment according to the requirement of thermal power plant wastewater zero discharge modification, if the solid content of the part of wastewater is ensured to be low, the desulfurization wastewater can be directly conveyed to a wastewater evaporation system for evaporation treatment without pretreatment, namely, part of good water with good quality and low solid content is screened from the wastewater and conveyed to an electric power generation system for recycling, so that the operation and maintenance cost of a power plant can be effectively reduced.
However, the existing desulfurization wastewater treatment technology is lack of wastewater screening treatment, particularly, in the wastewater treatment process of gypsum slurry, collection water taking points of low-quality water and high-quality water cannot be distinguished from wastewater, and the later stage of separate utilization and treatment of wastewater with different water qualities is inconvenient.
