SYSTEM AND METHOD OF NATURAL FLOW-TYPE RAINWATER TREATMENT USING NON-MOTORIZED EARLY RAINWATER EXCLUSION DEVICE

摘要

PURPOSE: A natural flow type system and method for treating rainwater using a non-motorized initial rainwater exclusion device are provided to improve purification efficiency by rapidly treating contaminants contained in rainwater. CONSTITUTION: A natural flow type system(1) for treating rainwater using a non-motorized initial rainwater exclusion device comprises a rainwater inlet(10), a non-motorized initial rainwater exclusion device(20), a natural flow type hybrid filtration device(30), a backwash water discharge device, a storage tank(50), a floating plant purification device(60), and a control panel(70). The rainwater inlet supplies initial rainwater to the initial rainwater exclusion device. The initial rainwater exclusion device continuously circulates contaminants contained in the supplied initial rainwater without power to firstly purify the initial rainwater. The natural flow type hybrid filtration device secondly purifies the firstly purified rainwater. The backwash water discharge device washes contaminants remaining in the hybrid filtration device. The storage tank stores the secondly purified rainwater. The floating plant purification device thirdly purifies the rainwater stored in the storage tank.
