PURPOSE: A pump for treating contaminated water is provided to disperse a gas being mixed with contaminated water at desired sizes and to discharge the gas through corresponding outlet ports according to the sizes, thereby enabling to selectively discharge the gas of a specific size. CONSTITUTION: A pump(30) for treating contaminated water comprises a housing(31), an gas inlet port(31a), a contaminated water inlet port(31b), a motor(32), impellers(33-1,33-2,33-3), and outlet ports(34-1,34-2,34-3). The gas inlet port is formed in the housing and a gas flows in. The contaminated water inlet port is formed in the housing and contaminated water flows in. The motor is installed in the inside of the housing. The impellers are axis-installed in a shaft(32a) of the motor at a predetermined interval. The outlet ports are formed in the housing by corresponding to each impeller one by one in a rear part. [Reference numerals] (AA) Control panel; (BB) Polluted water
