ABSTRACT

Hospitals represent an incontestable release source of many chemical and physical compounds in the environment due to laboratory activity or medicine excretion into wastewater. Waste water composition refers to the actual quantity of physical and chemical constituents present in the waste water. This in-depth study has led to greater understanding of the effluents discharged by hospitals. Physical and chemical analyses have been performed to characterize and assess the quality of waste water receiving untreated hospital effluents. Five time of samples per day corresponding to hospital activities. The results highlight that the effluents contained a moderate organic pollution. However, a numerous of specific pollutants were detected: COD. The mean content COD evaluated with 828.40 mg/L in effluent not exceeded the Domestic waste water fixed in maximal at 1000 mg/l. The BOD of effluent had mean values of 331.88 mg/L, while the mean of the DO concentration was 6.89 mg/L. The mean of the pH and water temperature of the influent wastewater were 7.29±0.83 and 21.93°C±2.48, respectively. A positive correlation, with significant (p
