Dynamic button, whole Waste Water Treatment enters automatic running pattern.Grid sewage-removing machine realizes intermittent operation under PLC effect,
Now one-level elevator pump brings into operation and supplies water to electrocatalytic oxidation equipment, and electrocatalytic oxidation equipment is started working, when comprehensive tune
When section pond is in low liquid level, in addition to Aeration fan time delay runs, other equipment is all out of service；Treat that water level returns to normal level
After level time delay 10 minutes, Waste Water Treatment is again introduced into normal operating condition.Water outlet enters in the middle of first after precipitation
Pond by two-stage hoisting pump, carries out Strong oxdiative process by inside waste water lifting to ozone catalytic tower, at the first middle pool water level
In back segment equipment when low liquid level in addition to Aeration fan time delay operation, other equipment is all out of service, treats that water level returns to normally
After fluid level, time delay entered normal operating condition after 10 minutes.Water outlet sequentially passes through the second intermediate pool, pretreatment pool and MBR
Membrane cisterna, realizes the product water process of its purified water by the continuous alternate run work of two product water self priming pumps in MBR membrane cisterna,
During produce water self priming pump start and stop controlled by PLC internal processes, in the present embodiment, every product water pump operation 8min, stop
Have a rest 2min, and every two product water self priming pumps of 120min carry out rotation.In addition, water level exceedes high level in MBR membrane cisterna, then one-level lifting
Pump is automatically stopped operation, and other equipment is normally run, and after the level to normal level to be restored, time delay enters normal fortune after 10 minutes
Row state, in MBR membrane cisterna water level be less than protection liquid level when two produce water self priming pumps all quit work, to be restored to normal level water
After flat, time delay entered normal operating condition after 10 minutes.Sterilization pool passes through connected sodium hypochlorite medicine machine and smelly
Purified water after oxygen equipment disinfection is promoted in device for ultrafiltration membrane further through three-level elevator pump and is processed, finally
A part of water outlet is stored in reuse pool, and another part standard water discharge is discharged.
Specifically, when needing a certain local devices are operated, after entrance system, click system is automatically stopped
Button, ends with system automatic running pattern, then pass through click system hand push button, enter system manual mode of operation, according to need
Will, specifically Non-follow control can be carried out to a certain or multiple devices, specifically enter operation pages click corresponding device startup and press
Button can achieve.
It is below the technological process of production of the present invention：The waste water of pharmaceutical manufacturing is by waste water sump evenly into grid
In spotter, remove oarse-grained suspension impurity through grid sewage-removing machine, then remove tiny graininess pollution through its fine fack
After thing substrate, water outlet gravity flow enters in comprehensive adjustment pond, and the tiny suspension particulate matter carried secretly in waste water is gradually deposited at synthesis
Regulating reservoir bottom, waste water quality and the water yield all obtain all with.Hereafter, by one-level elevator pump, waste water is equably promoted to electricity
