Remover of fluoride ion and treatment method for wastewater containing fluoride ion using the same

摘要

The present invention relates to a remover of dissolved fluoride ion for removing fluoride ions contained in wastewater and a treatment method for wastewater containing fluoride using the same. In order to achieve the above objects, the present invention provides a remover of dissolved fluoride ion comprising: a) hydrochloric acid solution reacted with calcium carbonate, and b) a mixture of poly sodium metaphosphate and active aluminum or aqueous solution of mixtures thereof, or an aqueous solution of rare earth element compound, and a treatment method for wastewater containing fluoride using the same. The present invention's removing agent for dissolved fluoride ion and treatment method for wastewater containing fluoride using the same can remove fluoride ion below 10 ppm easily and with low cost, can have the whole of the sludge generated from the treatment process reusable, can greatly reduce the time necessary for wastewater treatment by simplifying the conventional treatment process for wastewater containing fluoride which is complex, and can reduce labor costs as simpler equipment can be used to shorten the process.
