The structure of the control system, the assignment and implementation of the tasks, the control scheme and the design concept of program are expounded. The way of central monitoring management and dispersing control is used by the control system。 the long 一 distance control and monitoring of field equipment are uncharged of the upper puter。 the software program of designs uses Intouch7. 0. The specific technology, equipment, the controlling of main parameter and several running data are uncharged of the PLC stations, and the software program of designs uses Concept 2. 2XL with online tracking and outline simulating. MB+ is adopted by the munication between the upper puter and the PLC stations, with its simply building , quickly running and stable munication. The automatic control of PLC has been successfully pleted in sewage treatment, which has improved the operation efficiency and management level of sewage treatment equipment Introduced to take PLC as the distribute type control system of core in the wastewater treatment system of apply。 Concretely described the structure, mission of the control system an allotment and carry out, the way of control and the thought of the program design. The way controled the concentration monitor of the system adoption a management and scattered a control, the place of honor machine be responsible for the spot the long range of the equipments control and surveillance, software adoption Intouch7. 0 draw PLC native station is responsible for to the concrete craft, equipments and is mainly controled parameter to carry on control and collect various movement data, the program design adoption have online follow with offline imitate the Concept of true function 2. 2 XL of honor machine and of the PLC adoption set the be quickly simple and circulate speed, correspond by letter the stability strong MB+ whole control system successfully solved the PLC controls a problem in the automation within wastewater treatment and raised a wastewater treatment equipments to circulate an efficiency and manage level. Recently, for carrying out high quality, low consume, stable dependable and international many wastewater treatment factorieses adopted a modern forerunner to control technique and calculator technique and constitute calculator direct, control thus, manage system excellent to turn the programmable logic controller(PLC) then take microprocessor as the calculator technique automatically controls technique and correspondence technique but develops of a kind of new and in general use utomatic control structure simple, function superior, dependable sex Gao, work properly words in general use, be easy to plait distance, usage convenience etc. advantage etc..The silver Chuan City the first wastewater treatment factory adopted a SBR craft and take PLC as the control system of core, day after handling the sewage 10 104 t the processing of reach mark sewage can used for an agriculture irrigation. 1 Control system structure Control the way of concentration monitor management, scatter a control of the system emulation hold, place of honor machine, gather a line machine, printer to Be located on medium control room, two set PLCs are located on control the this kind of structure can make the information in the production line can centralized management with carry out whole operation, management with excellent make to control dangerous dispersion in the meantime, raise the system credibility. The upper puters Medium control two calculator adoption PII class works of room to control machine, circulate the operate system of Windows place of honor machine be responsible for on the scene establish each long ran
