| Popis: | Peak emergency discharges of harmful substances to the industrial companies waste waters that normally form coagulates over time present a serious environmental problem. These coagulates can enter natural water bodies during the wastewater discharge. Thus, detecting these coagulates in real-time is a relevant problem.To solve this problem, the authors suggest building an automated system that shall record and identify the emergency harmful substances discharges to the industrial companies waste waters caused by accidents. This system features a laser probing module which scans waste water at several wavelengths simultaneously and in real time.Emergency discharge identification is performed based on the substance transmission spectra analysis using the original description of the recorded substance spectra digital signals. The relative description on the components of the lattice function of the spectrum of emergency discharges is used, constructed using the order ratio between the components of the lattice function.The emergency discharge identification can be implemented by comparing the relative description of the emergency discharge spectrum with the reference spectra for the harmful substances that can be present at the given industrial facility, and the standards of the spectra of these substances are presented in the form of a relative description using the ratio “more”–“less”.The authors provide a flow chart for the emergency discharge elimination system, describe its operation and the functions fulfilled by its elements. The system features an emergency coagulate identification device, a processing device for the spectrum recorded that can also store the reference spectra of harmful substances, and a valve-control device for the waste water system. Due to installation of laser radiation sources along the perimeter of the pipe along which the liquid moves, simultaneous laser action on the emergency clot of harmful substances passing through the pipe is ensured. The analysis of the clot passing through the sewer pipe allows opening the valves for each of the predicted emergency clots when receiving a command from the control device and diverting the clot that has appeared to the appropriate sump. |
