Abstract

The invention discloses a device and method for treating high-fluorine-content water produced by an oil well and a coal-bed gas well. The device is characterized in that the high-fluorine-content water enters a primary fluoride removal device through a water pump A by an automatic pH control liquid adding machine and then simultaneously and equivalently flows into a secondary fluoride removal device A and a secondary fluoride removal device B, namely the two secondary fluoride removal devices are connected in parallel to run; when the content of fluorine in effluent does not reach the standards, the primary fluoride removal device, the secondary fluoride removal device A and the secondary fluoride removal device B are connected in series to run; when the content of the fluorine in the effluent still does not reach the standards, an alumina activation and regeneration unit and the primary fluoride removal device form a circulation loop to regenerate a fluoride removal filler, and meanwhile, the two secondary fluoride removal devices are regenerated; the high-fluorine-content water is discharged after reaching the standards. According to the device and the method disclosed by the invention, two adsorbents, namely activated aluminum oxide and a carbon ceramic composite material are combined during the use, advantages are enhanced, and disadvantages are avoided, so that the fluorine removal effect is effectively improved; the device is simple in structure, automatic in running and convenient to maintain and manage and reduces the running cost.

Description

technical field [0001] The invention relates to water treatment, in particular to a treatment device and a treatment method for high-fluorine water produced by oil wells and coal bed gas wells. Background technique [0002] Fluorine is one of the essential trace elements for human life. Every tissue in the human body contains fluorine, and the teeth, bones and hair contain the most fluorine. Appropriate amount of fluorine can make bones and teeth firm, reduce the incidence of dental caries, and is also beneficial to the excitatory conduction of the nervous system, phosphorus metabolism, parathyroid function, cell enzyme system and reproductive process. However, the harm of excessive absorption of fluorine to animals, plants and human body has far exceeded the impact of fluorine deficiency on human health. Excessive fluorine content will affect the metabolism of calcium and phosphorus in the human body, and make the material metabolism and physiological functions of the huma...
