PROBLEM TO BE SOLVED: To provide a forming method of making the aluminum floc obtained by electrolyzing waste water of car washing, etc., larger and a recycling method of converting the waste water of car washing, etc., to water for car washing. SOLUTION: The recycling method of the waste water of car washing, etc., is characterized by electrolyzing the waste water of car washing, etc., in an electrolytic cell 4 using aluminum as an electrode, delivering the scumming of the formed aluminum floc to a next reaction chamber 6 without removing the same, adding a highly bondable polymeric flocculant thereto in the reaction chamber to flocculate the scumming and to allow the scumming to float, then sticking the micro-air bubbles generated from the lower part of a floatation separation vessel to allow the scumming to float, delivering the water by a conveying pump 10, and recycling the water again as service water.
