Abstract

A comprehensive treatment method for mine water defluorination and boiler room desulfurization, which relates to the field of thermal power generation water treatment and environmental protection technology, and solves how to improve the utilization rate of defluoridation and desulfurization chemicals in thermal power plants, including defluorination of mine water and regeneration of filter materials for defluorination , Defluorination and desulfurization of waste liquid for reuse; empty the fluorine-containing NaOH concentrated liquid in the fluorine-removing filter tank and the regeneration liquid tank into the waste liquid pool, start the boiler room inlet pump to pump the fluorine-containing NaOH concentrated liquid in the waste liquid pool into the ash sink of the boiler room for the desulfurization reaction of the boiler room, and utilize the industrial grade Ca(OH) used in the ash sink of the boiler room 2 It reacts with fluorine-containing NaOH concentrated solution to remove fluoride ions, and integrates two independent systems of fluoride removal and desulfurization, which not only utilizes NaOH concentrated solution, saves caustic soda used in boiler rooms, but also utilizes industrial grade Ca(OH) 2 For defluoridation, saving food-grade Ca(OH) 2 The high cost has improved the utilization rate of fluoride and desulfurization drugs, and achieved obvious economic benefits.

Description

technical field [0001] The invention relates to the technical field of thermal power generation water treatment and environmental protection, in particular to a comprehensive treatment method for mine water defluorination and boiler room desulfurization. Background technique [0002] The ecological environment in Northwest my country has always been quite fragile, and water resources are seriously scarce. The development and utilization of groundwater has become an important way for people to use water for living. The groundwater in western my country generally has high fluorine content, which exceeds the sanitary standard for drinking water stipulated by the state. Long-term drinking of high-fluorine water may cause stained teeth and joint pain in mild cases, and affect bone development in severe cases, resulting in loss of labor force. Defluoridation of groundwater is a necessary link to ensure the sanitation of drinking water. [0003] One of the more advanced technologie...
