Method for controlling deodorization of aeration tank
专利汇可以提供Method for controlling deodorization of aeration tank专利检索，专利查询，专利分析的服务。并且PURPOSE: To reduce the size of a deodorizing device and to reduce the cost of the operation thereof by returning part of the smell generated from an aeration tank to a suction side of a blower so as to attain the min. oxygen concn. in the delivery flow rate of the blower at which the aeration tank provides the satisfactory function of an activated sludge method.
CONSTITUTION: The aeration tank 1 provided with a cap, the deodorizing device 2 for treating the smell and the blower 3 for aeration are provided. Part of the smell from the tank 1 is returned to the suction side of the blower 3 in the 1st fan 6 and part of the smell from the tank 1 is fed to the device 2 in the 2nd fan 9. The 2st wind flow regulating valve 31 is provided on the line to the suction side of the blower 3 via the fan 6 and the 2nd wind flow regulating valve 32 is disposed on the line to the device 2 via the fan 9. The valve 31 is controlled in the 1st control systems 18, 19 is such a manner that the delivery flow rate of the oxygen of the blower 3 attains the set oxygen concn. and the valve 32 is so controlled in the 2nd control systems 17, 20, 21 that the deviation between the controlled wind flow rate obtd. in the 1st control system and the delivery wind flow rate of the blower 3 is made zero.
