EVALUATION OF PHYSICOCHEMICAL AND BACTERIOLOGICAL PARAMETERS OF EFFLUENTS IN TAZA HOSPITAL-MOROCCO-APPLICATION OF PRINCIPAL COMPONENT ANALYSIS (PCA)

摘要

In order to manage and assess the effluents quality in Taza city provincial hospital center,sampling campaigns were carried out during one year (May 2018-April 2019).The wastewater physicochemical characterization revealed a very high organic matter load in terms of chemical oxygen demand (COD) (600.87 mg/L),biochemical oxygen demand (BOD5) (372.94 mg/L) and suspended matter (SM) (165.99 mg /L).However,COD / BOD_5 ratio varies between 2.10 and 1.69,showing a satisfactory biodegradability for this waste water.The bacteriological analyses results showed the presence of indicating fecal contamination germs,at very high concentrations for total coliforms (2.95 104/100 mL),fecal coliforms (5.93 10~3/100 mL) and fecal streptococci (4.810~3/100 mL).Statistical data processing gave us an idea about correlation between the different variables,thus principal component analysis (PCA) allowed us to reduce our database dimension by collecting as much information as possible about their trends.
