DEVELOPMENT OF TECHNOLOGY FOR MONITORING CHLORINE EMISSIONS INTO THE ATMOSPHERE DURING DISINFECTION OF WASTEWATER AT MUNICIPAL WASTEWATER TREATMENT PLANTS

The technology of automation of monitoring of the state of technogenic and ecological safety at urban treatment plants has been developed, as an executive body of the technology of environmental protection. A new automated monitoring system for the control of chlorine emissions into the atmospheric air has been developed and the technology for assessing the state of technogenic and ecological safety of treatment plants has been improved. The basis of the process of detecting chlorine emissions is a separate automated subsystem of gas analysis, which is a superstructure over the technological automation systems. The development of an automated monitoring system involves the use of modern electronic computing devices and specialized software to solve the functions assigned to it. The topology of the placement of measuring transducers of the gas analysis system has been developed based on technological maps of the decontamination process, taking into account the composition, location and characteristics of the main technological equipment. The use of meteorological parameter control technology in the designed automated monitoring system allows for the early development of management decisions to prevent the spread of a cloud of chemical contamination over a significant area, and the technology for predicting the spread of contamination in real time informs the operational and duty personnel of the facility about the possible consequences of the situation. Considering the lack of environmental monitoring of the state of atmospheric air at urban treatment facilities, the implementation of an automated monitoring system will allow for the control of one of the extremely dangerous factors of the wastewater treatment production process, which poses an environmental hazard not only to atmospheric air, but also to the environment as a whole. The developed environmental protection technology through the use of unified devices and protocols has a high coefficient of interchangeability of components and does not impose additional requirements on equipment, which makes it more adaptive.
