The invention relates to a precise control system for dissolved oxygen. Using the system, technical problems of poor automatic control and energy-saving effects and poor data recording and report analysis functions of the existing same kind of system can be solved. The control system comprises frequency conversion blowers, a primary settling tank, and dissolved oxygen pools. The system is characterized in that a main pipe pressure sensor and a main pipe blast capacity sensor are arranged successively at the pipeline connected to the frequency conversion blowers connected in parallel; and an atmospheric valve is arranged at a pipeline connected in parallel. The dissolved oxygen pools use dual-channel dissolved oxygen (DO) sensors to collect DOIT data. A PLC control system of a PLC controller carries out integrated and intelligent linkage control. An SCADA system in an operation station carries out monitoring on the equipment instruments. The PLC control system includes frequency conversion blower intelligent control instruments and a PLC intelligent control instrument; and the PLC intelligent control instrument is provided with a touch screen. The system has advantages of precise controlling, convenient operation, detailed data reading and recording, and good energy-saving effects.
Description
technical field [0001] The invention relates to an industrial sewage treatment system, which is a refined control system for dissolved oxygen. Background technique [0002] Sewage treatment refers to the process of purifying industrial or domestic sewage to meet the water quality requirements of a certain water body for drainage or reuse. The automatic industrial sewage treatment system generally adopts an intuitive display interface to realize graphical real-time monitoring of the production process and real-time display of various energy consumptions; at the same time, the system has carried out targeted design for energy saving and consumption reduction, and adopted various scientific methods for optimal control. For example: carry out joint control of pumping station units, optimize scheduling, reduce energy consumption, and prolong the service life of the unit; automatically analyze water quality data, calculate the appropriate proportion of medication, and save medicat...
