FLOCCULATION BASIN FOR TREATMENT OF DRINKING WATER AND WASTEWATER

摘要

PURPOSE: A flocculation basin for treatment of drinking water and wastewater is provided to remarkably reduce the size of a structure and a site area by shortening flock forming time. CONSTITUTION: A filter-type flock forming module(2) forms fine particles in flock. When processing target water is collided with a wall firstly in a mixing flock forming module(3), an eddy is formed. The inter-particle collision is induced through a stirring operation in an eddy forming process. In an upflow-type flock forming module(4), rising speed is increased. The rising speed of large flock is reduced. In a mechanical mixing flock forming module(5), the flock is formed through the rotation of the mixing device.
