Abstract
The utility model relates to a treatment of domestic sewage field specifically is an aquatic dissolved oxygen automatic regulating apparatus. An aquatic dissolved oxygen automatic regulating apparatus, including the good oxygen pond of being equipped with domestic sewage, install be used for measuring dissolving oxygen analyzer, intake stack, installing electrical control valve that being used for on the intake stack adjusted the intake, installing the pressure sensor that is used for measuring intake stack internal pressure on the intake stack, install fan on the intake stack, providing converter, the PLC system of power for the fan of domestic sewage oxygen content in good oxygen pond. The control that has realized getting rid of organics in water's oxygen content in water to sewage biochemical treatment in -process to the energy and cost of labor have been practiced thrift.
Description
Technical field
This utility model relates to sanitary sewage disposal field, specifically a kind of oxygen in water self-checking device.
Background technology
In the biochemical treatment operation of domestic sewage processing system, in order to remove Organic substance in water content, need through aerobic
Process.According to technological requirement, the dissolved oxygen of Aerobic Pond to control in the range of 2-4mg/L, and this is accomplished by being entered by aerator
Row aerobic aeration, and control aeration rate, aeration rate number to regulate by measuring the dissolved oxygen content in water.
Owing to water is being continually changing, Organic substance in water content also changes at any time, and the amount of supporting changes therewith well.Therefore, need
There is a set of oxygen in water Automatic adjustment method, it is achieved aeration rate is automatically controlled, and ensure aeration pressure, in order to be steady
Determine the oxygen content of Aerobic Pond, meet technological requirement.
Summary of the invention
Technical problem to be solved in the utility model is: the most molten by controlling in aeration rate and aeration Stress control water
Solve oxygen content, to meet the condition of technique removal Organic substance in water.
This utility model be the technical scheme is that a kind of oxygen in water self-checking device, including equipped with life
The Aerobic Pond of sewage, it is arranged in Aerobic Pond for measuring the dissolved oxygen analytic instrument of sanitary sewage oxygen content, intake stack, installation
Being used on intake stack regulates the electric control valve of intake, is arranged on intake stack for measuring inside intake stack
The pressure transducer of pressure, the blower fan being arranged on intake stack, fan provide the converter of power, PLC system, dissolved oxygen
Analyser, electric control valve, pressure transducer, the converter signal of telecommunication connect PLC system.
This utility model in use dissolved oxygen analytic instrument measures the real-time of the Aerobic Pond equipped with sanitary sewage in real time
Dissolved oxygen value, and real-time dissolved oxygen value is sent to PLC system, compare with the standard dissolution oxygen value preset in PLC system, work as reality
Time dissolved oxygen value more than or less than quasi-dissolved oxygen value time, PLC system control electric control valve reduce or increase intake, directly
To meeting real-time dissolved oxygen value and be in the scope of standard dissolution oxygen value, simultaneously during motorized adjustment valve regulation, pressure sensing
The pressure of device can fluctuate, and pressure transducer is sent to PLC system real-time pressure, the standard pressure default with PLC system
Relatively, when real-time pressure is more than or less than normal pressure, PLC system controls converter to be increased or reduces rotating speed force rate, from
And adjust intake stack internal pressure, until real-time pressure is in typical pressure range.
The beneficial effects of the utility model are: automatically adjusted by a set of oxygen in water of two closed loop interlock system compositions
Regulating device, it is achieved that the control to the water oxygen level removing Organic substance in water in biochemical processing procedure of sewage, and saved energy
Source and cost of labor.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Wherein, 1, dissolved oxygen analytic instrument, 2, Aerobic Pond, 3, intake stack, 4, electric control valve, 5, pressure transducer, 6,
Blower fan, 7, converter.
Detailed description of the invention
As it is shown in figure 1, this utility model includes two closed loop interlock systems, first by dissolved oxygen analytic instrument, electric adjustable
Joint valve, PLC system composition, second is made up of converter, pressure transducer, PLC system, and this utility model is in the process of use
In, it is necessary first to rule of thumb with calculating at preset standard dissolved oxygen value (such as 2-4mg/l) and typical pressure range (0.2-
0.4MPa).When measurement sometime is to when being dissolved oxygen value 1.5 mg/l in real time, and PLC system controls electric control valve increase and enters
Air quantity, until meeting real-time dissolved oxygen value inside critical field (2-4mg/l) scope, simultaneously because air intake quantitative change is big thus enters
Pressure within airduct diminishes, be likely to result in cannot gas cruelly, now PLC system detects the real-time pressure of pressure transducer
(0.15 MPa) is less than typical pressure range, and now PLC system controls converter and increases rotating speed, thus adjusts inside intake stack
Pressure, until real-time pressure is in typical pressure range.
Claims (1)
1. an oxygen in water self-checking device, it is characterised in that: include the Aerobic Pond equipped with sanitary sewage, be arranged on
In oxygen pond for measure the dissolved oxygen analytic instrument of sanitary sewage oxygen content, intake stack, be arranged on intake stack for adjusting
Save the electric control valve of intake, be arranged on intake stack for measuring the pressure transducer of intake stack internal pressure, peace
The blower fan that is contained on intake stack, fan provide the converter of power, PLC system, dissolved oxygen analytic instrument, electric control valve,
