The aim of the research was defining influence temperature of the sewage flow from sewage system and the temperature of the atmospheric air on tempera-ture sewage in open biological reactor of flow. To research one chose the small sewerage system with the sewage treatment plant serving to 2000 PE (Population Equivalents) situated on the village-commune in the malopolska voivodeship. Within a period of research the sewerage accompanied sewage from 250 buildings. The average flow of sewage in the investigated year was from 110 to 120 m3•d-1. The research embraced the period of 12 months from 1 January to 31 December the year 2010. To describe this relationship used of the multiple re-gression of analysis. In the period of research ascertained the large variability of the average temperature of sewage flow from sewage system and large variability of average of the temperature of the atmospheric air. The average of mean daily temperature of sewage flow was 11.0 oC. The lowest of temperature of sewage flow was 4.9 oC and the highest was 20.5 oC. In the investigated year of mean daily of the temperature of the atmospheric air was 8.3 oC. The research of concerning of multiple regression of ...
