PROBLEM TO BE SOLVED: To provide a method which does not require any pH value adjustment and pretreatment; also does not require a large-scale, high-cost engineering work and any investment in equipment; continuously purifies a large volume of fouled running water and forcibly creates a water current by artificially saved energy consumption in a closed broad stagnant water area and thereby separates contaminants by flocculation to be grown and effects rapid purification to realize a purified successful condition. SOLUTION: This method efficiently employs a mixed and stirred water current generating function effectively combined with the characteristics of a naturally produced inorganic flocculation effect exerting material and an ultra-energy saving-type rocking reversal motion mechanism. In other words, the method makes the best use of the function to separate and purify a large water volume of a fouled dispersion dispersed over the entire area through a process of efficiently mixing, stirring and flocculating into a growth by the help of a vortical water current created by the rocking reversal motion mechanism, in utilizing the function to rapidly mix a flocculation function exerting agent with water to be treated and the vortical water current. Thus, the running fouled water of rivers and the closed large water area which are stagnant and contaminated is purified. COPYRIGHT: (C)2005,JPO&NCIPI
