Sewage treatment plants are primarily designed to ensure that effluent meets regulatory discharge standards. The treatment process typically involves two key stages: first, disinfection of the sewage, followed by real-time monitoring of various water quality parameters using water quality detectors. Unsurprisingly, human labor is indispensable for the operation of such facilities. However, working in sewage treatment plants entails a non-negligible risk of poisoning. The underlying reasons are as follows:
The influent of sewage treatment plants mainly consists of domestic sewage, industrial wastewater, and medical wastewater. During transportation through municipal pipeline networks, the water is often in an oxygen-deficient state. In the subsequent treatment process, toxic and hazardous gases may be generated, dissolved, or released, thereby exposing workers to poisoning risks. For example, accidental contact with or inhalation of liquid chlorine, sulfuric acid, or chemical flocculants used in the treatment process can lead to poisoning incidents. Therefore, it is crucial to attach great importance to this issue and implement comprehensive protective measures.
Incidentally, what is the function of the water quality detector mentioned earlier? In essence, this instrument is employed for real-time monitoring of multiple water quality parameters. By comparing the detected data with relevant standards, it is possible to determine whether the water quality exceeds the permissible limits. If all parameters are within the standard range, the effluent can be discharged. Conversely, if any parameter exceeds the standard, further treatment is required until all indicators meet the specified criteria before discharge.
