A chemical treatment apparatus includes an outer bath; an inner bath, located inside the outer bath; a circulation system, connecting the outer bath to the inner bath; and a draining system, having a first draining pipe and a connecting pipe, wherein the connecting pipe connects the first draining pipe to the circulation system. The suction force generated by a pump of the circulation system is thereby transferred to the first draining pipe. Therefore when the chemical solution is to be drained out from the inner bath, the draining of the chemical solution into the first draining pipe can be quickly done with the aid of the suction force.
