[Abstract]:Today, with the continuous progress of the production automation level of tobacco industry enterprises, the increasing production of tobacco products and the continuous expansion of the scale of enterprises, the burden of sewage treatment in tobacco enterprises has been increasing. The problem of high energy consumption in sewage treatment is becoming more and more prominent. In order to realize the overall goal of energy saving and emission reduction in tobacco enterprises, it is a problem that tobacco enterprises have to face to optimize and adjust the automatic control system and technological process of wastewater treatment. This paper takes the control system of BAF treatment and reuse of industrial wastewater of cigarette factory as the research object. Firstly, it introduces the principle of the process flow of wastewater treatment and reuse of BAF type, that is, adopting advanced biochemical technology, taking hydrolytic acidification tank and aerated filter as the main body. Treatment of waste water from tobacco industry; The energy consumption of the related equipments in the key process of sewage treatment is analyzed to find out the opportunities of saving energy and reducing consumption. According to the analysis of energy consumption, the optimization of control system for aeration fan and flocculant addition system is emphatically carried out, and the corresponding energy-saving optimization control methods and strategies are put forward. The theoretical basis of the corresponding advanced control method is described in detail. Through field test and debugging, it has a good effect on saving energy and reducing consumption of cigarette wastewater treatment and optimizing operation of equipment. According to the requirements of the sewage treatment process and equipment in cigarette factory, the hardware of the control system is selected and designed. The S7x300 series PLC of Siemens Company is used as the control unit, and the characteristics and connection modes of each function module of PLC are introduced respectively. The bus connection based on Profinet network is established by using S _ 7 ~ (7) ~ (300) series communication module. In order to prevent the disturbance of the control system, the protection grounding method of the control system and the shielding grounding method of the field network are analyzed. The control system connects the sewage treatment control system with the energy control system through the industrial Ethernet with optical fiber as the medium. Through the field bus technology, the control system realizes the data connection and communication between the field equipment layer and the operation control layer, and completes the automatic control and remote monitoring of the sewage treatment system. The programming of the control system in this paper is based on the Step7 software of Siemens Company. The Step7 software has a powerful function, which provides a convenient tool and interface for the programmers, and can conveniently realize the multi-person division and cooperation, and has hardware configuration to the PLC. Network parameters configuration, fault diagnosis, off-line programming control program and on-line monitoring and other functions can be configured, network configuration and connection can be configured, hardware upload and download, and off-line simulation through the simulator. The Intouch software of Wonderware company is used as the monitoring and configuration software of the upper computer in the central control room, and the rich plug-in and drawing tool of Intouch software are used to realize the integration and image display of the sewage control system, and the alarm tool is used. Monitor the parameters of each link. The data report forms are used to query the parameters and real-time curves of the control system so as to provide data support for the optimization of each technological process and condition monitoring and facilitate the tracing of the data. The real-time monitoring technology of sewage quality is used to analyze the water quality on-line. Compared with the traditional control method, the automatic monitoring and control system of cigarette wastewater has a higher degree of automation, and is connected seamlessly with the energy control system in the factory area. It has the effect of saving energy and reducing consumption, and has certain application value.
