Quan Xing.
（3）Acid-base neutralization processing of the present invention can avoid traditional PID regulation sides using artificial add alkaline methods are simulated
Formula can not abundant neutralisation treatment vacancy, guarantee makes to be further processed again after waste water pH value is qualified, to sufficiently achieve discharge
Standard.
Brief description of the drawings
Fig. 1 is the system principle diagram of the present invention.
Fig. 2 is the acid-base neutralization device flow chart of the present invention.
Embodiment
The present invention is described in further detail with reference to embodiment, but the implementation of the present invention is not limited to this.
It is worth noting that, in the practical application of the present invention, software program, but applicant are inevitably applied to
It is hereby stated that the software program that the technical scheme is applied in the specific implementation is all prior art, in this application, it is not related to
To the change and protection of software program, simply to realize the protection of hardware structure that goal of the invention designs.
Embodiment：
A kind of control system of the power station wastewater treatment based on PLC, as shown in figure 1, including PLC master controllers, relay
Device operating room, wastewater treatment place, the relay operation room include embedded controller and auxiliary reclay, the relay
Auxiliary reclay at least two in operating room, it is divided into input auxiliary reclay and output end auxiliary reclay, the PLC
Master controller is connected with embedded controller, the output end auxiliary reclay connection embedded controller, in the input
Between relay connection embedded controller, the wastewater treatment place is provided with contactor, acid-base neutralization device, sewage disposal are set
Standby, monitoring device, contactor are provided with contactor normally opened contact, contactor normally opened contact connection input intermediate relay, contact
Device one end connects output end auxiliary reclay, contactor other end connection acid-base neutralization device, at acid-base neutralization device and sewage
Manage equipment connection；The system uses the control model of upper and lower computer, and host computer uses PLC master controllers, and as slave computer
Embedded controller is communicated using RS485, and host computer is mainly completed to gather the data message of each system and equipment in real time, from
It is dynamic that computing arrangement, the statistics form after arrangement is handled are carried out to data message, and Real time dynamic display is real on picture
Actual value, data message is automatically saved, and export corresponding controlled quentity controlled variable, when monitoring system monitors sewage disposal scene parameters
Meeting automatic alarm, alarm form are represented on PLC master controllers in a manner of picture during beyond preset standard or abnormal state, are monitored
System mainly includes processing pit level, acid-base value, sewage disposal device motor are detected and monitored；The waste water processing station
Monitoring device one end connection embedded controller in ground, other end connection sewage disposal device, slave computer embedded controller
Primary recipient passes through the on-site signal of input auxiliary reclay transmission, is uploaded to after the processing of embedded controller chip upper
Machine, host computer send signal according to the standard figures of setting to embedded controller, then by order through relay among output end
Device transmits the regulation for the sewage disposal device in wastewater treatment scene, completing sewage disposal device.
Because processing waste water total amount reaches hundreds of tons daily, and initial pH value differs greatly, and the sediment in water is not yet
Equally, so being difficult to adopt traditional regulative mode carries out acid-base neutralization processing, as shown in Fig. 2 the acid-base neutralization device bag
PH value measuring appliance and agitator are included, manually plus by the way of alkali is adjusted using simulation：When processing pond reaches given water level,
Start acid-base neutralization regulation, add alkali first to open agitator before starting and stir, make the well mixed measuring appliance pH value again of waste water, work as PH
<When 2.5, system control persistently plus alkali, during PH=2.5-4, add-subtract time T1, during PH=4.01-5, add-subtract time T2, PH=
During 5.01-6, add-subtract time T3, acid-base value is qualified during PH=6.01-8.5, without adding alkali, PH>When 8.5, exit and add alkali, by alkali
Property water extract out a part into the tank of slant acidity；PH measuring appliances are in running order all the time in acid-base value regulating system,
Moment measures real-time pH value, to sufficiently achieve acid-base value standard, is further processed.
The present invention is reasonable in design, using core of the embedded controller as the wastewater treatment control system, its main work(
The data of each system can be gathered for the processing equipment and realizing in control wastewater treatment place, have that system power dissipation is small, practicality
