Standby, the water after being handled through device for ultrafiltration membrane enters reuse pool or qualified discharge, reuse pool, wherein, electrocatalytic oxidation is set
Slag equipment deslagging pipeline connection scum silica frost pond is scraped in standby, the pipeline of vertical sedimentation tank and the MBR membrane cisterna connects storage mud respectively
Pond.Described sterilization pool is carried out disinfection by connected sodium hypochlorite medicine machine and ozone devices.In addition, described
Reuse pool connects frequency-conversion water supply system.In addition, auxiliary equipment of the present utility model also include diving mixer, Aeration fan,
Sludge reflux pump, production water self priming pump, backwash centrifugal pump and hypochlorous acid medicine machine.
The utility model realizes programme-control by PLC automation control systems to each processing equipment.Its specific works is former
Reason is as follows：Into the PLC control system page, display automated system operation and system run two kinds of operational modes manually, click on system
System automatic button, whole wastewater treatment equipment enters automatic running pattern, and grid sewage-removing machine realizes intermittent fortune under PLC effects
OK, now one-level elevator pump is brought into operation and supplied water to electrocatalytic oxidation equipment, and electrocatalytic oxidation equipment is started working, and works as synthesis
When regulating reservoir is in low liquid level, in addition to Aeration fan delay operation, other equipment is out of service；Treat that water level returns to normal liquid
Position level and after being delayed 10 minutes, wastewater treatment equipment is again introduced into normal operating condition, and water outlet enters in first after precipitation
Between pond and by two-stage hoisting pump, Strong oxdiative processing will be carried out inside waste water lifting to ozone catalytic tower, when the first middle pool water level
During in low liquid level in back segment equipment in addition to Aeration fan delay operation, other equipment is out of service, treats that water level is returned to just
After normal fluid level, delay enters normal operating condition after 10 minutes.Water outlet sequentially pass through the second intermediate pool, pretreatment pool and
MBR membrane cisternas, realize the production water mistake of its purified water in MBR membrane cisternas by the continuous alternate run work of two production water self priming pumps
Journey, the start and stop that water self priming pump is produced in the process are controlled by PLC internal processes, in the present embodiment, every production water pump operation
8min, the 2min that rests, rotation is carried out per two production water self priming pumps of 120min.In addition, water level exceedes high level in MBR membrane cisternas, then
One-level elevator pump is automatically stopped operation, and other equipment is normally run, it is to be restored arrive normal level level after, delay 10 minutes it is laggard
Enter two production water self priming pumps when water level is less than protection liquid level in normal operating condition, MBR membrane cisternas to be stopped, it is to be restored to just
After normal fluid level, delay enters normal operating condition after 10 minutes.Sterilization pool is set by connected sodium hypochlorite dosing
The standby and ozone devices purified water after processing that carries out disinfection further is promoted in device for ultrafiltration membrane through three-level elevator pump and carried out
Processing, final a part of water outlet is stored in reuse pool, the discharge of another part standard water discharge.
Specifically, when needing to operate a certain local devices, into after system, click system is automatically stopped
Button, ends with system automatic running pattern.Again by clicking on system hand push button, into system manual mode of operation, according to need

Button is that can be achieved.
It is the technological process of production of the present utility model below：The waste water of pharmaceutical manufacturing by waste water sump evenly into
In grid sewage-removing machine, the suspension impurity of bulky grain is removed through grid sewage-removing machine, then through the tiny graininess of its fine fack removal
After pollutant matrix, water outlet gravity flow enters in comprehensive adjustment pond, and the tiny suspension particulate matter carried secretly in waste water is gradually deposited at
Comprehensive adjustment bottom of pond portion, waste water quality and water by and.Hereafter, by one-level elevator pump, waste water is equably promoted to electricity
In oxidation equipment, the organic pollution in this stage waste water participates in electrochemical reaction process jointly, in external dc power supply
In the presence of, most of difficult degradation larger molecular organicses inside solution are gradually degraded, and are produced in electrochemical reaction process
Flco class material will be in the presence of electric field, the Al being electrolysed out with anode material3+、Fe3+Deng metal ion, stabilization is formed
Complex compound, the countless H that a part of complex compound will be produced by negative electrode2、O2Micro-bubble takes liquid surface to, and passes through electrocatalytic oxidation
Change the scum silica frost doctoring apparatus above equipment, scraped and drained into scum silica frost pond, another part complex compound will be gradually deposited at electro-catalysis
Oxidation furnaces bottom, can be removed it, the supernatant after being handled through electrocatalytic oxidation equipment by periodically turning on the form of mud valve
Liquid, water outlet gravity flow enters vertical sedimentation tank, and the cotton-shaped complex compound of part sedimentation not yet in effect will be under gravity at sedimentation basin bottom
Portion is deposited, and supernatant then flows automatically into the first intermediate pool, is promoted to the waste water solution after clarification by two-stage hoisting pump smelly
In oxygen oxidizing tower, the ozone produced with ozone generator is passed through into the waste water solution in tower, by air-water contact equipment, by ozone
Carry out being sufficiently mixed contact with waste water, it is using the Strong oxdiative feature of ozone that the hardly degraded organic substance in waste water is further abundant
Ground is degraded to degradable small organic molecule, greatly improves the biodegradability of waste water, and water outlet enters pre- anti-after the second intermediate pool
Ying Chi, under the collective effect of facultative microbe, realizes the further degraded and removal to Wastewater Pollutant matrix, and water outlet is certainly
Stream enters in MBR membrane cisternas, under aerobic microbiological, including ammonifiers, the comprehensive function of nitrifier, carries out ammonification, nitration reaction,
Efficiently separating to the purified water after processing and pollutant impurity is realized through MBR membrane modules again, the water outlet after processing, which is flowed through, to disappear
Malicious pond, under ozone and hypochlorous collective effect, kills the pathogenic microorganisms and virus in water outlet, the water outlet after sterilization is through three
Level elevator pump is promoted in device for ultrafiltration membrane, final deep purifying processing is carried out, to ensure the final safety of water outlet after processing
Stability, until meeting qualified discharge or flowing into be recycled in reuse pool utilize.
