Shenyang Xinhua Sewage Treatment Control System PLC/DCS Automation Project
Sewage treatment DCS control system, sewage treatment automation system, sewage treatment solution, sewage treatment PLC control system, Shenyang Xinhua undertakes sewage treatment PLC/DCS automatic control system project, through the sewage treatment DCS control system to carry on the automatic control to the sewage treatment process and automatic Adjustment, so that the treated water quality indicators meet the technical indicators. Shenyang Xinhua can provide sewage treatment solutions under different technologies, modular structure, with the advantages of simple commissioning, easy operation, safe use, high efficiency, low failure rate, good sewage treatment effect, easy operation and maintenance.
First, the scope of application
The sewage treatment control system provided by Shenyang Xinhua is an automatic control and automatic adjustment of the sewage treatment process, so that the treated water quality indicators meet the technical indicators and meet the national environmental protection requirements.
Second, the process characteristics
Sewage is generally divided into domestic sewage, industrial wastewater, agricultural sewage, and medical sewage according to the source. The process includes aeration biological filter, SPR, A/O method, MBFB membrane biological and many other technologies. Shenyang Xinhua can provide automatic control system solutions for sewage treatment processes under different technologies, modular structure, with simple debugging, easy operation, safe use, high efficiency, low failure rate, good sewage treatment effect, easy operation and maintenance, etc. .
Third, the system composition
The automatic control of the sewage treatment process is realized through a self-control scheme, which is mainly a sequential logic control. According to Shenyang Xinhua's requirements for automatic control systems, the design of the control system is divided into three parts: the development of the electrical part, the PLC program, the development of the host computer monitoring software WinCC, and finally the realization of the process control, operation and monitoring management of the sewage treatment system. There are reliable hardware devices, as well as powerful, reliable, user-friendly system software, application software, programming software, and control software. Operation and maintenance costs are low and operation is easy.
The entire control system is divided into three levels, namely, field level, control level, and management level. The management level centrally monitors the operation status of each substation device and collects field data at the same time. The main function of the control level is to receive the parameters or commands set by the management level to control the production process of the sewage treatment. The main operating parameters (water quality parameters, flow rate, liquid level, etc.), operation status and the main period of time during the operation process Information such as process curves are sent to management.
In addition, the control system can also achieve the following functions:
1) Control operation: The on-line real-time control of the controlled device can be performed in the central control room, such as starting and stopping a certain device, adjusting the size of some analog output, and setting certain parameters of the PLC online.
2) Display function: Display real-time running status of controlled devices in each field, as well as status parameters of each site.
3) Data Management: According to the speed of change of different operating parameters and the degree of importance, establish a production history database, store the production of raw data for statistical analysis, and display some necessary parameters and results to the real-time screen and reports.
4) Alarm function: When an analog quantity (such as current, pressure, water level, etc.) exceeds a given range or a switch quantity (such as motor start and stop, valve switch) valve dislocation, according to different needs Different levels of alarms are issued.
5) Print function. Reports and graphics can be printed, as well as real-time printing of various events and alarms.
As an excellent service provider in the field of automation, Shenyang Xinhua Control Systems Co., Ltd. has accumulated rich engineering cases in the industry. In recent years, Xinhua has successfully implemented waste heat power generation, building intelligence, heat exchange stations, air conditioning, boiler control, alcohol control, molasses alcohol, ground dust removal, sewage treatment, waste gas treatment, power plant desulfurization, and coal for hundreds of companies. The control system engineering projects for gas production and thermal power plant coal transportation program control have been operating safely and stably so that they can effectively realize the good economic and social benefits for customers and are highly praised and trusted by customers.
