摘　　要：研究了超细轻质CaCO_3沉降的各种影响因素,并对其进行了絮凝沉降实验,发现复合絮凝沉降效果较好,其速率可达未加絮凝剂的10～12倍。After studying a variety of factors affecting precipitation of ultrafine light CaCO3,the flocculation settling tests were followed. The best effect was found in combined flocculation test,whose speed reached 10-12 times as high as that with nothing added.
