摘要
In a fluoride including waste water processing device which comprises a reaction vessel and a sedimentation vessel, a calcium compound adding device adds calcium compound in fluoride including waste water in the reaction vessel to react the calcium compound with fluoride of the fluoride including waste water to generate calcium fluoride. The sedimentation vessel has a bottom which is associated with a bottom of the reaction vessel through an opening hole. The fluoride including waste water is sent to the sedimentation vessel from the reaction vessel through the opening hole. The sedimentation vessel has an inclined bottom surface. The calcium fluoride is sent back, by a self-weight of the calcium fluoride, to the reaction vessel from the sedimentation vessel along the inclined bottom surface. An agitator aggregates the fluoride including waste water in the reaction vessel. A polymer solution adding device adds polymer solution in the fluoride including waste water in the reaction vessel. A supernatant liquid draining device drains supernatant liquid of fluoride including waste water from the sedimentation vessel.
