Description
Technical field
The utility model is related to a kind of modified backwashing system, belongs to backwashing technology field in sewage disposal system.
Background technology
In sewage disposal system, filter tank is the important step in water factory's water-purifying process, and the regeneration of filter ability,
It is the key of filter tank stable and high effective operation.According to preferable backwashing technology, make filter tank often in being worked under optimal conditions,
Can not only economize on water, energy-conservation, moreover it is possible to increase water quality, increase filtering layer retaining power, extend the work period, improve aquifer yield.Cause
The quality of this backwash effect is the key of filter tank stable and high effective operation.There are the following problems for existing filter back washing：（1）Backwash
It is cumbersome, it is impossible to remote control；（2）Whether sand filter wants backwash, and whether backwash is thorough, on-the-spot make an inspection tour is needed, by sand filter
Liquid level and backwash water turbidity judge that work is passive, complicated, and particularly night shift backwash, liquid level and turbidity cannot be seen clearly；（3）Sand filtration
The outdoor construction in pond, algae reproduction speed is fast, blocks sand filter, influence filter effect, artificial removal's workload big；Winter temperature
Low, the growth of microorganism of sand filter surface attachment is suppressed, intake of the influence microorganism on influence polluter in water, reduces
Removal effect.
The content of the invention
A kind of problem that the utility model exists for existing sand filter, there is provided modified backwashing system.The backwash
System should set up Central Control Room PLC, realize a key backwash；Liquid level gauge is set up, according to sand filter liquid level backwash sand filter, control
Sand filtration pit level；Set up the transmissometer Based Intelligent Control backwash time；Color steel room is added a cover, algae reproduction is controlled.By controlling algae
Breeding, improves backwash technique, lifts sand filter backwash effect, and then lift sand filter filter capacity, it is ensured that effluent quality.
The technical solution adopted in the utility model is：A kind of modified backwashing system, it includes V-type sand filter, quartz
Sand filtering material, V-groove, distributing hole, air distribution hole, rhone, backwashing pump and backwash blower fan, it also include transmissometer, liquid level gauge and in
Control room PLC, liquid level gauge is installed in the V-type sand filter, and transmissometer is installed in rhone, and liquid level gauge and transmissometer will be measured
Signal transmission is to Central Control Room PLC；The Central Control Room PLC works according to setup parameter, when the liquid level gauge in V-type sand filter is detected
When liquid level reaches setting height, Central Control Room PLC starts backwashing system, and backwashing pump and backwash blower fan are opened and backwashed, instead
Rinse sewage and enter rhone, turbid ity signal is transferred to Central Control Room PLC by the transmissometer in rhone, is set when turbidity of sewage reaches
During definite value, Central Control Room PLC stops backwashing system.
The beneficial effects of the utility model are：This modified backwashing system is additionally arranged transmissometer, liquid level gauge and middle control
Room PLC, liquid level gauge is installed in V-type sand filter, and transmissometer is installed in rhone, and liquid level gauge and transmissometer pass measurement signal
It is defeated to Central Control Room PLC, Central Control Room PLC works according to setup parameter.The backwashing system sets up PLC, realizes a key backwash；Increase
If liquid level gauge, according to sand filter liquid level backwash sand filter, sand filtration pit level is controlled；When setting up transmissometer Based Intelligent Control backwash
Between；Color steel room is added a cover, algae reproduction is controlled.By controlling algae reproduction, backwash technique, lifting sand filter backwash effect are improved
Really, so lifted sand filter filter capacity, it is ensured that effluent quality.
Brief description of the drawings
Fig. 1 is V-type sand filter schematic diagram.
Fig. 2 is counter-flushing process figure.
In figure：1st, V-type sand filter, 2, quartz sand filter media, 3, V-groove, 4, distributing hole, 5, air distribution hole, 6, rhone, 7, turbid
Degree instrument, 8, liquid level gauge, 9, Central Control Room PLC, 10, backwashing pump, 11, backwash blower fan.
Specific embodiment
Fig. 1,2 show a kind of schematic diagram of modified backwashing system.In figure, this modified backwashing system includes
It is V-type sand filter 1, quartz sand filter media 2, V-groove 3, distributing hole 4, air distribution hole 5, rhone 6, backwashing pump 10, backwash blower fan 11, turbid
Degree instrument 7, liquid level gauge 8 and Central Control Room PLC 9.Liquid level gauge 8 is installed in V-type sand filter 1, transmissometer 7 is installed in rhone 6,
Measurement signal is transferred to Central Control Room PLC 9 by liquid level gauge 8 and transmissometer 7.Central Control Room PLC 9 works according to setup parameter, works as V-type
When liquid level gauge 8 in sand filter 1 detects liquid level and reaches setting height, Central Control Room PLC 9 starts backwashing system, backwashing pump 10
Opened with backwash blower fan 11 and backwashed, backwashing sewage water enters rhone 6, transmissometer 7 in rhone 6 is by turbid ity signal
Central Control Room PLC 9 is transferred to, when turbidity of sewage reaches setting value, Central Control Room PLC 9 stops backwashing system.
Using above-mentioned technical scheme, liquid level gauge is set up in sand filter, when sand filtration pit level reaches the setting upper limit,
Start automatic backwash, liquid level reach setting lower limit when, reduce sand filter outlet valve open degree, prevent sand filter filtrate exposed
In air.
Turbidity measurement instrument is installed, judges whether backwash is thorough by the turbidity for detecting.
Increase PLC module in control room, advanced treating sand filter back-washing equipment electric signal is introduced into control room, when being set as
Manually during control, with a key backwash, but hand switch can be needed, switched to when automatically controlling, when sand filtration pit level reaches certain height
After degree, the incoming Central Control Room of liquid level signal, sand filter backwashing system is automatically turned on, and is reached when Turbidity measurement instrument detects backwash water turbidity
During to setting value, turbid ity signal is sent to Central Control Room, and backwashing system is automatically switched off, the detection of sand filter transmissometer.
Color steel room is added a cover on sand filter pond, it is to avoid sunlight irradiates sand filter, causes algae reproduction；Prevent winter temperature
It is low, influence microbial activity.
Specific implementation process rises for sand filtration pit level, and liquid level signal is transferred to control room by liquid level gauge, and control room sends
Signal starts automatic back-washing, and backwash water is discharged by dirt discharge groove, transmissometer detection turbidity of sewage, after delivery turbidity reaches requirement,
Transmissometer sends signal to control room, and control room transmission signal stops backwash.
