Abstract:Zbrali smo podatke monitoringa za odpadne vode in odpadno blato na komunalni čistilni napravi od leta 1999 do 2004. Dodatno smo pridobili še podatke monitoringa za leto 2007 za mesec november in december. Za obdelavo rezultatov meritev smo uporabili različne kemometrične metode: osnovne statistične metode za določitev povprečne vrednosti in mediane, standardnega odmika, minimalne in maksimalne vrednosti merjenih fizikalno kemijskih parametrov in njihove medsebojne korelacijske koeficiente, metodo glavnih osi ter linearno diskriminantno analizo. Z metodo glavnih osi in linearno diskriminanto analizo smo poskusili poiskati podobnosti med posameznimi vzorci. Proučevali smo vpliv meseca, leta in letnega časa. Ugotoviti smo želeli, kakšna je kakovost odpadne vode na dotoku, iztoku ter skupno na dotoku in iztoku od leta 1999 do 2004. Nato smo podatke iz let 1999 do 2004 primerjali s podatki iz leta 2007, da bi ugotovili, ali se je kakovost odpadne vode skozi leta izboljšala. Podatke za odpadno blato od leta 1999 do 2004 smo prav tako kemometrično obdelali in ugotovili, da je kakovost blata skozi leta slaba, da ni prišlo do spremembe oziroma do izboljšanja kakovosti blata.

Title:DETERMINATION OF WASTE WATER AND WASTE SLUDGE QUALITY FROM WASTE WATER TREATMENT PLANT USING CHEMOMETRICS METHODS
Abstract:Data from monitoring of waste water and waste sludge were gathered from waste water treatment plant during 1999 to 2004. Additionally data from year 2007 for two months, namely November and December were provided. For data evaluation different chemometric methods were used: basic statistical methods for determination of mean and median values, standard deviation, minimal and maximal values of measured physical and chemical parameters and their mutual correlation coefficients, principal component analysis and linear discriminant analysis. With principal component analysis and linear discriminant the similarities between individual water or sludge samples were tried to find. The influence of different month, year and season of sampling on classification of waste water was studied. The quality of input and output waste waters from waste treatment plant was examined from year 1999 to 2004.These data were compared with the monitoring data from year 2007 to find out if the quality is improved during years. Data from waste sludge monitoring were also chemometrically processed. It was established that the quality of waste sludge is all the time poor and that no improvement of waste sludge quality is observed
Keywords:chemometrics, waste water quality, principal component analysis (PCA), linear discriminant analysis (LDA)
