Abstract
The utility model relates to a kind of aerobe pond aeration rate automatic-adjusting device, for the control of aerobe pond aeration rate in Sewage treatment systems, belongs to technical field of sewage.This device measures the dissolved oxygen content in biological tank by the dissolved oxygen instrument be arranged on aerobe pond, and dissolved oxygen instrument is connected by communication cable with PLC device, middle control computer, gas blower.PLC device controls the unlatching number of units of gas blower and regulates the frequency of blower variable frequency device, and the dissolved oxygen content in aerobe pond is maintained near given oxygen value.This device is as a constant Controlling System, and the given optimal dissolution oxygen value remained unchanged of system, well, controlled volume is short to the time of set-point transition for its stability and kinetic characteristic, and process is steady simultaneously, and oscillation amplitude is little.
Description
Technical field
The utility model relates to a kind of aerobe pond aeration rate automatic-adjusting device, for the control of aerobe pond aeration rate in Sewage treatment systems, belongs to technical field of sewage.
Background technology
Aerobe pond is the core of wastewater treatment plant using activated sludge process, and the degraded of dirty water pollutant mainly completes in aerobe pond, and therefore the operation conditions in aerobe pond determines treatment effect and the working cost of whole system to a certain extent.Dissolved oxygen affects the normal operation in aerobe pond, reasonably controls the processing efficiency that dissolved oxygen effectively can improve aerobe pond.
Summary of the invention
For solving problems of the prior art, the utility model provides a kind of aerobe pond aeration rate automatic-adjusting device, to ensure the stable of oxygen level in aerobe pond.
The technical scheme that the utility model technical solution problem adopts is: a kind of aerobe pond aeration rate automatic-adjusting device, it comprises aerobe pond, described aerobe pond is provided with the dissolved oxygen instrument for measuring oxygen level, and aerobe pond is connected with gas blower by supply air line; Be connected with middle control computer by communication cable with the PLC device of operating frequency for controlling gas blower opening times, middle control computer is connected with gas blower by communication cable again, is connected between PLC device with dissolved oxygen instrument by communication cable.
The quantity that described device is provided with gas blower is 2-4 platform.
The beneficial effects of the utility model are: this device measures the dissolved oxygen content in biological tank by the dissolved oxygen instrument be arranged on aerobe pond, and dissolved oxygen instrument is connected by communication cable with PLC device, middle control computer, gas blower.PLC device controls the unlatching number of units of gas blower and regulates the frequency of blower variable frequency device, and the dissolved oxygen content in aerobe pond is maintained near given oxygen value.This device is as a constant Controlling System, and the given optimal dissolution oxygen value remained unchanged of system, well, controlled volume is short to the time of set-point transition for its stability and kinetic characteristic, and process is steady simultaneously, and oscillation amplitude is little.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of aerobe pond aeration rate automatic-adjusting device.
In figure: 1, gas blower, 2, dissolved oxygen instrument, 3, PLC device, 4, middle control computer, 5, aerobe pond, 6, supply air line, 7, communication cable.
Embodiment
Fig. 1 shows a kind of aerobe pond aeration rate automatic-adjusting device, and it comprises and is arranged on for measuring the dissolved oxygen instrument 2 of oxygen level on aerobe pond 5, and gas blower 1 is by supply air line 6 to aerobic biological tank air feed, and this device is provided with 2 gas blowers 1.Be connected with middle control computer 4 by communication cable 7 with the PLC device 3 of operating frequency for controlling gas blower 1 opening times, middle control computer 4 is connected with gas blower 1 by communication cable 7 again, is connected between PLC device 3 with dissolved oxygen instrument 2 by communication cable 7.
When adopting technique scheme work, dissolved oxygen content in the real-time control measurement aerobe pond 5 of dissolved oxygen instrument 2, for this sewage work, Control for Oxygen Content in aerobe pond 5 is at 2-4mg/l, when oxygen level exceeds this scope, dissolved oxygen instrument 2 transmits guard signal by communication cable 7 to PLC device 3, PLC device 3 controls the unlatching of gas blower 1 by middle control computer 4 again and regulates the frequency of frequency transformer, adjust to the blast volume in aerobic biological tank 5, for reaction tank aerobic section provides oxygen, and maintain the dissolved oxygen value of aerobic processes.By the operation screen of middle control computer 4, the dissolved oxygen value of aerobic biological tank 5 can be set.
