Description
Technical field
The utility model is related to a kind of dissolved oxygen automatic control system, belongs to technical field of sewage.
Background technology
In sewage disposal system, using the sewage treatment plant of activated sludge process, dissolved oxygen is one of its regulation and control important
Parameter, whether appropriate dissolved oxygen adjustment is directly affects effluent quality.Dissolving oxygen demand is provided by blower fan, and blower fan leads to dissolved oxygen
Pipeline transport is crossed in Aerobic Pond.The air quantity of existing process adjustment blower fan needs to exist by portable dissolution apparatus or dissolved oxygen
After the measurement of line monitor, according to the size of the dissolved oxygen for detecting, blower fan frequency is manually adjusted, change air quantity, then measure dissolving
Oxygen, until in system dissolved oxygen it is suitable untill.Because amount of inlet water fluctuation is larger, sludge concentration also fluctuates within the specific limits,
So that system had repeatedly change to the demand of dissolved oxygen among one day, and detect dissolved oxygen, manually adjust blower fan frequency, again
Detection dissolved oxygen is more time-consuming, and can not accomplish accurately and timely, molten if air quantity adjustment is inaccurate, not in time
The solution too high waste of resource of oxygen, dissolved oxygen is too low to influence effluent quality.
The content of the invention
The utility model is big for existing dissolved oxygen adjustment workload, and not in time, waste of resource influences system stabilization for adjustment
The shortcomings of, there is provided a kind of dissolved oxygen automatic control system.Flowmeter is installed on the water inlet pipe of aeration tank, Aerobic Pond end is installed
Dissolved oxygen monitor, Central Control Room PLC changes blower fan frequency by receiving inflow signal, dissolving oxygen signal.So as to ensure dissolving
Oxygen adjustment is timely, accurate, automation, it is ensured that system run all right, reduces operating cost.
The technical solution adopted in the utility model is：A kind of dissolved oxygen automatic control system, it includes Aerobic Pond, dissolved oxygen
Detector and frequency conversion fan, it also includes feed water flow gauge and Central Control Room PLC, and the feed water flow gauge is arranged on entering for Aerobic Pond
On water pipe, Aerobic Pond end install dissolving oxygen detection, the feed water flow gauge, dissolving oxygen detection and frequency conversion fan with
Central Control Room PLC is electrically connected, the Central Control Room PLC dissolving oxygen detection, the output gas-water ratio parameter of feed water flow gauge with
Setting gas-water ratio parameter 4-5:1 compares, make respective feedback, feedback signal transmission to the frequency conversion fan in air blast computer room, frequency conversion
Blower fan adjust automatically frequency, the dissolved oxygen in adjustment Aerobic Pond.
The beneficial effects of the utility model are：This dissolved oxygen control system includes Aerobic Pond, dissolving oxygen detection, frequency conversion
Blower fan, feed water flow gauge and Central Control Room PLC, feed water flow gauge are arranged on the water inlet pipe of Aerobic Pond, are pacified in the end of Aerobic Pond
Dress dissolving oxygen detection, feed water flow gauge, dissolving oxygen detection and frequency conversion fan and Central Control Room PLC are electrically connected.The control
The Central Control Room PLC of system changes blower fan frequency by receiving flow of inlet water signal, dissolving oxygen signal, adjusts air quantity, changes system
Interior dissolved oxygen.So as to ensure that dissolved oxygen adjustment is timely, accurate, automate, it is ensured that system run all right, operating cost is reduced.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of dissolved oxygen automatic control system.
In figure：1st, water inlet pipe, 2, feed water flow gauge, 3, Aerobic Pond, 4, dissolving oxygen detection, 5, Central Control Room PLC, 6, air blast
Computer room, 7, gas pipeline.
Specific embodiment
Fig. 1 shows a kind of schematic diagram of dissolved oxygen automatic control system.Fig. 1, this dissolved oxygen automatic control system bag
Include Aerobic Pond 3, dissolving oxygen detection 4, frequency conversion fan, feed water flow gauge 2 and Central Control Room PLC5.Feed water flow gauge 2 is arranged on
On the water inlet pipe 1 in oxygen pond 3, dissolving oxygen detection 4, feed water flow gauge 2, dissolving oxygen detection 4 and are installed in the end of Aerobic Pond 3
Frequency conversion fan is electrically connected with Central Control Room PLC5, and Central Control Room PLC5 is dissolving oxygen detection 4, the output gas of feed water flow gauge 2
Water is than parameter and setting gas-water ratio parameter 4-5:1 compares, and makes respective feedback, feedback signal transmission to the change in air blast computer room 6
Frequency blower fan, frequency conversion fan adjust automatically frequency, the dissolved oxygen in adjustment Aerobic Pond 3.
Using above-mentioned technical scheme, when the flow of inlet water of system changes, Central Control Room PLC5 receives changes in flow rate letter
Number, Central Control Room PLC5 is according to gas-water ratio 4-5:1 automatically analyzes, and adjusts blower fan frequency or the Fans of open and close one.In end dissolved oxygen
During change, Central Control Room PLC5 receives dissolved oxygen variable signal, and the standard of air quantity adjustment is to control in 2-3mg/l dissolved oxygen,
Central Control Room PLC5 adjusts blower fan frequency or the Fans of open and close one by this standard.
