PURPOSE:To deodorize a malodor and use wasted heat efficiently, by installing a heat exchanger of hot water in an exhaust gas duct of a gas turbine generator which uses for its combustion, the air in a treating room for isolating a sewage treatment plant which is made under the ground in the basement of a building, and circulating the hot water in a pipe line under the floor of the building. CONSTITUTION:A treating room 2 in which sawage is treated and a generator room 3 in which power is generated are made under the ground in the basement of a building 1 which has some kinds of facilities, for instance, a gymnasium and a movie theater, in a upper floor over the ground. In the treating room 2 a treatment plant which consists of a sand sedimentation tank 4, a aeration tank 5, a precipitation tank 6, a nitrating tank 7, a denitrification tank 8 and a flocculating sedimentation tank 9, is installed. And an outlet air duct and an inlet air duct 14 are installed facing each other in the treating room 2, whose inside pressure is adjustable to negative. The inlet air duct 14 is connected to a supplying duct 32 through which the air in the treating room 2 is transported to a gas turbine generator 17 as air for combustion by a fan 12. Besides, installing a heat exchanger 18 in an exhaust gas duct from the gas turbine generator 17, and getting hot water heated by exhaust gas, then the hot water is circulated through a heat storage tank in a pipe line arranged under the floor of the building 1.
