WASTE WATER TREATMENT METHOD
PROBLEM TO BE SOLVED: To provide a method for treating concrete wastewater in which, while the treatment performance is excellent, the treatment cost can be reduced.SOLUTION: In the method: particles S1,S2 are removed from a concrete wastewater C1 to give a clear water C2; the calcium ions in the clear water C2 is ion-exchanged with hydrogen ions to give carbonated water C3; the carbonated water C3 is neutralized with clear water C2 to give neutralized water C4; and the calcium carbonate in this neutralized water C4 is removed to give effluence C5 that can be discharged to a river or the like.SELECTED DRAWING: Figure 1
【課題】処理性能が優れていながら、処理コストを抑えることができるコンクリート排水の処理方法にする。【解決手段】コンクリート排水Ｃ１から粒子Ｓ１，Ｓ２を取り除いて清浄水Ｃ２を得、この清浄水Ｃ２中のカルシウムイオンを水素イオンにイオン交換して炭酸水Ｃ３を得、この炭酸水Ｃ３を清浄水Ｃ２で中和して中和水Ｃ４を得、この中和水Ｃ４中の炭酸カルシウムを取り除いて河川等に放流することができる処理後の排水Ｃ５を得る。【選択図】図１
