wastewater - Opis:
- Purified water daily discharged to surface water from local sewage treatment plants can cause illnesses people and animals in nearby areas. Sometimes they also contribute to the development of diseases in much bigger region range. Often the cause of such infections are pathogenic Listeria rods especially Listeria monocytogenes, which are not eliminated in the technological process of wastewater treatment carried out by local sewage treatment plants. Therefore, the purpose of the study was to investigate the influence of the sewage treatment plant on the presence of Listeria bacteria and to estimate the potential hazard resulting from its occurrence in the water of the Warta River. Research points were located on the Warta River before and after the discharge of purified sewage through the treatment plant, also a direct exit of purified wastewater was examined. Samples were filtered and then estimated the growth characteristics of typical colonies on the selected diagnostic media were estimated and isolated microorganisms were characterized. Samples were filtered and then it had been defining the growth characteristics of typical colonies on the selected diagnostic media, finally isolated microorganisms were described. Studies have shown that the local wastewater treatment plant has a strong influence on the microbial quality of the Warta River and has shown strong impurity with Listeria rods, including pathogenic strains. Bearing in mind the results obtained, it can be stated that direct or indirect contact with receivers of the water of purified sewage poses a real threat to the health and even life of humans and animals.
