PURPOSE: To reutilize waste water of a car washing machine, by collecting waste water after washing a car, in a pit, sucking it up to a waste water purifying device, and separating and removing impurities such as a detergent, wax, etc. mixed in waste water, in the device.
CONSTITUTION: A titled device is constituted of a P it P for collecting waste water being under the installation face of a car washing machine Wc , a waste water purifying device C for sucking up waste water in the pit P and separating and removing impurities, and a clean water tank T for collecting clean water from the device C. The purifying device C consists of an electrolytic cell 18 for separat ing primarily impurities a jet device S for mixing air in waste water from the lower part and jetting it to said cell, a separating chamber 28 for separating secondarily waste water overflowing from the electrolytic cell 18, an impurity receiving tank 31 being adjacent to said chamber, an impurity guide plate 61, a jet nozzle 62 for forming a jet water flow going toward said plate and extruding impurities (a) of the separating chamber 28 to the impurity receiving tank 31, and a filtration chamber 16 for filtering waste water from the separating chamber 28.
