Title: Batch treatment of waste water and its device
Inventor: MIHASHI KAORU
IPC: C02F3/12
Filed: 1987-12-29
Abstract: PURPOSE:To enable batch treatment of waste water at low cost by pressing a curtain- like material with the drive of a water current generator to reduce the volume of an inflow chamber, permitting the settlement of sludge and the discharge of supernatant liquid during the pause of operation and moving the curtain-like material in a direction in which the volume of the inflow chamber is increased in response to an increase of incoming water. CONSTITUTION:Water is allowed to flow into a water inflow chamber 1a inside a waste water treatment tank 1 from a waste water supply source, and a water current is generated in a treatment chamber 1b by means of a water current generator 5. Further, a curtain-like material 1a suspended in the treatment tank is pressed to the inflow chamber 1a by the water pressure to reduce the volume of the inflow chamber. The water of the inflow chamber is gradually moved into the treatment chamber from the lower edge of the curtain-like material. The generation of the water current is allowed to be suspended for a specified time after the lapse of a specified time. Then the settlement of sludge and discharge of supernatant liquid are permitted during the pause time. In addition, the curtain-like material 2 is shifted to the treatment chamber side in response to an increase of water inflow, and the volume of the inflow chamber is increased to prevent the mixing of the supernatant liquid with water due to water overflow.

Abstract: PURPOSE:To allow the circuit to cope with a signal level change automatically by providing a circuit feeding back 1/m (m is a positive integer) of a DC component of a comparator output voltage to a noninverting input and a 1/n (n is a positive integer and m>n) of the DC component of the comparator output voltage to an inverting input. CONSTITUTION:Part of an output extracted from an output of a comparator 1 via a resistor R3 is fed back to the inverting input of the comparator 1 via a resistor R4, part of the output of a resistor R3 is fed back also to a noninverting input via a resistor R5. The resistance is selected as R1=R3=R4=R5 and R2=2R1 so that a 1/3 of the output voltage is fedback to the noninverting input and a 1/2 voltage is fed back to the inverting input. Since there is a difference between the noninverting input and the inverting input in the feedback quantity, the mean output voltage is fed back negatively. That is, the mean value of the output voltage is selected to be a desired value by setting the circuit constant properly.
