Calcium removal method of calcium containing wastewater and calcium removal equipment

摘要

EspeciallyIn treating calcium containing wastewater with high calcium concentrationThe removal of the scale fixed to the reaction tank member of the calcium removal facility can be facilitated andBy reducing the frequency of workCalcium removal equipment can improve maintenanceCalcium removal methods and calcium removal facilities for calcium containing wastewater.Calcium removal method of calcium containing wastewater of the present inventionCalcium containing wastewater as treated waterIt is introduced through at least one of piping or a predetermined vesselThe introduced calcium containing wastewaterIt is introduced into reaction vessel 12 to react with carbonate to generate calcium carbonate.The reaction vesselSaid predetermined vesselA scale softening agent is added to at least one of the pipes.Thus, the scale is softened to facilitate the removal work.Diagram
