The invention belongs to the field of environment protection technology and relates to a simulation method for infrared dynamic synchronous monitoring of flocs. The method comprises the following steps: (1) a certain amount of a coagulant is added into wastewater in a coagulation reactor 7, and character capture of flocs is carried out by three infrared detectors 1; and (2) an acquired flocs signal is sent to a frame grabber, a multi-channel signal of a flocs space is obtained, the signal is transmitted to a mobile workstation 3, undergoes information processing and enters a digital converter 4, high-resolution sampling of a digital signal is completed, a result is sent to a programmable controller 5, the signal is sent back to the mobile workstation after digital editing is completed, data is transmitted to a graphic workstation 6 after selection to finish simultaneous simulation of flocs, and a flocs simulation model is outputted. Through research and development of the above simulation system for infrared dynamic synchronous monitoring of flocs, characters of flocs can be acquired, stored and simulated at real time. Meanwhile, synchronous detection control of flocs images is realized, and coagulation effect of wastewater is mastered at real time.
Description
technical field [0001] The invention relates to a simulation method for infrared dynamic synchronous monitoring of flocs, which can be used for simulation of floc structures in the coagulation stage of urban water treatment. Background technique [0002] During water treatment, the fractal properties of flocs play an important role in regulating the transport and removal of particulate matter. In the flocculation process, only flocs with appropriate particle size and strong binding force can be formed to resist various shear forces that appear during the subsequent solid-liquid separation and improve the subsequent treatment effect. Therefore, the research and establishment of floc growth model has practical guiding significance for the control of coagulation process operating conditions. [0003] However, due to the lack of methods used in floc simulation at present, the fitting degree between the model and the floc structure is not high, and the representativeness is poor...
