Description
[technical field]
This utility model relates to sewage disposal system, particularly relates to a kind of MBR membrane cisterna and cleans Adding medicine control system
System.
[background technology]
At present, according to " membrane separation process sewage disposal code technical specification " and " integral type film biological reactor
Sewage disposal application technology code " described in existing MBR system process in sewage, Treated sewage reusing project,
MBR membrane treatment process has the advantage that other sewage treatment process are incomparable, and its solid-liquid separation efficiency is high,
Effluent quality after process is good, and floor space is little, and process equipment is concentrated, it is adaptable to take up an area limited sewage
Processing system.
But owing to the sludge concentration in sewage or middle water is the highest, cause the viscosity of mud mixed liquid to steeply rise,
And the rising of viscosity, have led to the drastically decline of membrane flux, after membranous system work certain time in mixed liquor
Suspended contaminant etc. can reduce the permeability of film in varying degrees, form fouling membrane so that MBR film warp
Membrane pollution problem often occurs, thus needs frequent clean membrane module, the various chemical agents used during cleaning,
As the highest in prices such as hypochlorous acid citric acids, cost can be caused to waste if do not controlled use, and most medicament
Containing Acidity of Aikalinity, it is not neutralized discharge and can cause environmental pollution, do not meet the principle of energy-saving and emission-reduction.
[utility model content]
This utility model provides a kind of compact conformation, easy to control, and automaticity is high, it is possible to effectively save
The MBR membrane cisterna of cost cleans control system for adding drugs.
In order to realize above-mentioned utility model purpose, the technical solution adopted in the utility model is:
A kind of MBR membrane cisterna cleans control system for adding drugs, including neutralizing tank and the MBR being arranged in neutralizing tank
Film, this system also includes that PLC regulates control centre, distribution center, dosing pump, converter, automatic valve
Door, electromagnetic flowmeter, PH meter and ultrasonic level gage, the cleaning drug feeding pipeline of dosing pump connects to have and runs through
The cleaning pipeline of MBR film；Described automatic valve is arranged on the bottom of neutralizing tank, and described electromagnetic flowmeter is pacified
Being contained in cleaning drug feeding pipeline, described PH meter is arranged in neutralizing tank with ultrasonic level gage and adjusts to PLC
Saving the current pH value of control centre's Real-time Feedback and height of liquid level, PLC regulates control centre and counts according to PH
Calculate required dose with ultrasonic level gage real-time measurements and regulated by Frequency Converter Control dosing pump
The frequency of dosing, neutralizing tank is arranged by automatic valve automatically to after in it, MBR film is neutralized after dosing
Put.
Preferably, described cleaning pipeline is arranged at the bottom of neutralizing tank.
Preferably, described cleaning pipeline is arranged at intervals with some high velocity projectors.
The beneficial effects of the utility model are:
This utility model regulates, by PLC, the PID intelligent control program that control centre is arranged, according to MBR
The pollution level of film is different, is automatically adjusted the flow of dosing pump to realize saving dose.
Meanwhile, the control system of PLC regulation control centre can record dosing flow, dosing pump frequency, medicine
The historical datas such as liquid PH, equipment working state, both can make alarm, and facilitate again user monitoring to divide
Analysis, prompting user；And stand-by equipment is automatically started when device damage.
It addition, the control system of PLC regulation control centre is internal uses multiple-factor algorithm routine, can according to
The chemical feeding quantity of family setting or the required chemical feeding quantity of calculating automatically, meet MBR Membrane cleaning effect premise in guarantee
The most farthest saving medicament, average pharmaceutical quantities of saving reaches 20%.
[accompanying drawing explanation]
Fig. 1 is schematic diagram of the present utility model.
[detailed description of the invention]
A kind of MBR membrane cisterna cleans control system for adding drugs, as it is shown in figure 1, include neutralizing tank 1 and be placed on
MBR film 2 in neutralizing tank 1, this system also includes that PLC regulates control centre's (not shown), joins
Electrfic centre (not shown), dosing pump 3, converter 4, automatic valve 5, electromagnetic flowmeter 6, PH count
7 and ultrasonic level gage 8, the cleaning drug feeding pipeline 30 of dosing pump 3 connects to have and runs through the clear of MBR film 2
Wash pipeline 9；Described automatic valve 5 is arranged on the bottom of neutralizing tank 1, and described electromagnetic flowmeter 6 is arranged on
Clean in drug feeding pipeline 30, described PH meter 7 and ultrasonic level gage 8 is arranged in neutralizing tank 1 and to
PH value that PLC regulation control centre Real-time Feedback is current and height of liquid level, PLC regulation control centre according to
PH meter 7 and ultrasonic level gage 8 real-time measurements are calculated required dose and are controlled by converter 4
Dosing pump 3 regulates the frequency of dosing, and neutralizing tank 1 leads to after in it, MBR film 2 is neutralized after dosing
Cross automatic valve 5 automatic-discharging sewage.
Continue, as it is shown in figure 1, this cleaning pipeline 9 is arranged at the bottom of neutralizing tank, to clean and be spaced on pipeline 9
It is provided with some high velocity projectors 10.
During use, PLC regulates the PID intelligent control program that control centre is arranged, according to the dirt of MBR film
Dye degree is different, is automatically adjusted the flow of dosing pump to realize saving dose；And, during PLC regulation controls
The control system of the heart can also record dosing flow, dosing pump frequency, medicinal liquid PH, equipment working state etc.
