For example, the treated water 1 after the first treatment is supplied to an aeration tank 2 where activated sludge and denitrification treatments are carried out. The sewage is introduced into a precipitation tank 3 where solid-liquid separation is carried out, and then is supplied to a rapid stirring tank 4. To the tank 4 supplied sodium hydroxide and a coagulant such as aluminum sulfate from agent-supply devices 6, 7 with stirring rapidly. The mixture is transferred to a slow stirring tank 8. To the tank 8 are supplied high molecular coagulant from an agent-supply device 9 and chlorine gas from a supply device 10 with stirring slowly. Further, the treated water is transferred to a coagulating preciptation tank 11 and the floc is separated and the decolorized supernatant liquid is discharged.

Title: Speed controller for dc motor
Inventor: OKADA YASUHIRO
IPC: H02P7/288
Filed: 1982-05-26
Abstract: PURPOSE:To facilitate the regulation of the rotating speed of a DC motor and to reduce the reactive current of the motor by altering slightly an external driven circuit. CONSTITUTION:A constant current source is composed of a reference voltage source 5, resistors 6-8 and transistors 9, 10, and a constant current Ia is flowed to resistors 11, 4. The positive and negative input terminals of a voltage comparator 12 becomes equal voltage state in the motor control state. Accordingly, Ea+RaIa=RTIT+RsIs (IT=Ia/K, where K means current distribution ratio) exists. Then, since Ea=KaN (where N means the rotating speed of the motor 1, and Ka means constant.) exists, the rotating speed N varies linearly to the variation in the rotating speed regulating resistance Ra. The reactive current which does not contribute to the motor torque is reduced.
