METHOD FOR TREATING MICROCYSTIS IN LAKE, MARSH, POND OR THE LIKE AND DEVICE

摘要

PURPOSE: To surely and efficiently separate Microcystic from water regardless of the kind of Microcystis and to reduce the operation cost of a device. ;CONSTITUTION: This device for treating Microcystis in lakes, marshes, ponds, etc., comprises a coagulatin tank (1) for coagulating and separating the Microcystic from raw mater (w) to be treated, a pressing and concentrating tank (8) for concentrating the coagulated Microcystics (A), an electric treating tank (17) provided with electrodes (19) for applying a direct electric current for the perfect separation of the water from the concentrated coagulated Microcystis (A), and a tank (37) for electrically treating the supernatant water provided with electrodes (39) for applying a direct electric current for the treatment of the supernatant water (CW) of the pressing and concentrating tank (8). The coagulated Microcystis (A) floated and separated in the upper part of the electric treating tank (17) can be taken out, dehydrated and dried to recover as a solid cake.;COPYRIGHT: (C)1995,JPO
