The present invention relates to a pipe cleaning method using an ultrasonic fine bubble to clean a contaminated water supply pipe using water pressure and air. The present invention comprises: a first removal of an impurity inside a pipe by water pressure of water; a second removal of an impurity inside a pipe by high-pressure air; a third removal of an impurity inside a pipe by a bubble; and a fourth removal of an impurity inside a pipe by ultrasonic waves. The removal is sequentially repeated, thereby effectively removing an impurity such as rust, scale, and slime. |
