Quick-coagulation sedimentation water purification method

Abstract

Abstract Translated from Japanese (57)【要約】 【構成】 本発明は各種原水中の浮遊物を沈降槽内で凝 集沈降させて浄水する際、凝集沈降剤として軟磁性材 (ferrite)又は従来公知のアルミニウム、第２鉄塩等の 凝集沈澱剤で処理した軟磁性材を使用する速成凝集沈降 浄水方法。 【効果】 本発明によれば従来の凝集沈澱剤を使用した 場合に比べて凝集沈降速度が速いので沈澱槽のサイズを 小さくすることができ、一度使用した軟磁性剤磁力選別 により回収して再使用することができる。 (57) [Summary] [Structure] The present invention uses a soft magnetic material as a flocculating / precipitating agent when purifying water by flocculating suspended matter in various raw water in a sedimentation tank. (ferrite) or a rapid-coagulation sedimentation water purification method using a soft magnetic material treated with a coagulation-sedimentation agent such as conventionally known aluminum or ferric salt. [Effects] According to the present invention, the flocculation and sedimentation speed is faster than that in the case of using the conventional flocculation-precipitation agent, so that the size of the precipitation tank can be reduced, and the soft magnetic agent used once is recovered and re-collected by magnetic separation. Can be used.
