<P>PROBLEM TO BE SOLVED: To provide a cutting water circulation system for concrete cutter which has excellent mobility, convenience and waste water treatability in the construction site, and can reuse cutting waste water without contaminating the peripheral environment. Ž<P>SOLUTION: The cutting water circulation system S for concrete cutter is composed of: a stirring tank 1 into which cutting suspension waste water generated when asphalt or concrete is cut is made to flow; a precipitator 2 connected to the stirring tank 1 via a partition 2a; a dehydrator 4 for slurry provided at the lower part of the stirring tank 1; a clean water tank 3 connected to the precipitator 2 via a partition 3a; an air pump 5 subjecting the inside of the stirring tank 1 to aeration stirring and further circulating reservoir water after dehydration to the stirring tank 1; a first filter F1 filtering sludge made to flow into the stirring tank 1; and a second filter F2 further filtering supernatant water in the precipitator 2. Wherein, an inorganic neutral flocculant is added to the stirring tank 1, the precipitator 2 and the clean water tank 3. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
