PROBLEM TO BE SOLVED: To eliminate the need for stationary places and to allow inexpensive and versatile utilization by casting a machine body in such a manner that its installation position can be changed, supporting a decomposition treatment tank in this machine body and providing the machine body with a waste water suction mechanism, microorganism feed mechanism, aeration mechanism, heating mechanism, treated water return mechanism, or the like. SOLUTION: The waste water purification device 1A is constituted by disposing the decomposition treatment tank 3, the waste water suction mechanism 6, the microorganism feed mechanism 7, the aeration mechanism 8 and the treated water return mechanism 11 on the movable machin body 2 having wheels 13. The outside surface in the upper part of the decomposition treatment tank 3 is provided with a vacuum pump 14 for generating a negative pressure in the decomposition treatment tank 3. The suction port 14a of the vacuum pump 14 is inserted into the decomposition treatment tank 3. In addition, a waste water transporting member 5 capable of sucking up the waste water in an interceptor 4 is connected to the upper part of the decomposition treatment tank 3. The waste water transporting member 5 and the vacuum pump 14 constitute the waste water suction mechanism 6. As a result, fat and oil-containing waste water in the interceptor 4 existing in another position may be sufficiently decomposed and purified without requiring the stationary place.
