摘要：Leachate from a non-sanitary municipal solid waste landfill (L) was collected to perform physico-chemical (temperature, pH value, conductivity, COD, BOD5, NH4+-N, SO42-, Ptot, orthophosphates, turbidity, suspended solids) and microbiological (number of aerobic heterotrophs, total number of coliform bacteria, total number of faecal coliform bacteria, number of intestinal enterococci) analyses. Obtained results indicate that landfill L was in methanogenic phase of waste decomposition and included the presence of two species of microorganisms: Escherichia coli and Klebsiella pneumonia. Additionally, a semi-quantitative screening analysis of collected samples was performed using QP2010-Ultra GC-MS. Sixteen organic compounds were identified, of which the following five belonged to the group of pharmaceuticals: caffeine, 22-tricosenoic acid, 4-methylthiomorpholine-1,1- dioxide, 2,6,10,14-hexadecatetraen-1-ol,3,7,11,15-tetramethyl-,acetate,(E,E,E)-, and 1,2- bis(trimethylsilyl)benzene. The software package STAN was used to conduct material and substance flow analysis. Scenario modeling was performed to assess the removal efficiency of selected technologies in terms of reducing the concentration of caffeine because of its well-known negative effects on humans and the environment. Technologies for leachate treatment, which were observed within the Scenario 1, included the hybrid wetland system, membrane bioreactor (MBR) and reverse osmosis (RO). The modeling results indicate the high removal efficiency of caffeine concentration (99.99%).
其他摘要：U sklopu istraživanja analizirana je procjedna voda iz obodnog kanala nesanitarne deponije čvrstog komunalnog otpada unutar lokaliteta L. U prikupljenim uzorcima vode određivani su: osnovni fizikalno-kemijski (temperatura, pH vrijednost, električna vodljivost, HPK, BPK5, NH4+-N, SO42-, ukupni fosfor, ortofosfati, zamućenost i suspendirane tvari) i mikrobiološki parametri (broj aerobnih heterotrofa, ukupan broj koliformnih bakterija, ukupan broj koliformnih bakterija fekalnog porijekla, broj crijevnih enterokoka). Analizom rezultata osnovnih fizikalnokemijskih parametara, može se zaključiti da se deponija nalazi u metanogenoj fazi degradacije otpada. Rezultati mikrobiološke analize ukazuju na prisutnost dvije vrste mikroorganizama: Escherichia coli i Klebsiella pneumonia. Primjenom QP2010-Ultra GC-MS realizirana je i polukvantitativna probirna analiza prikupljenih uzoraka, kojom je utvrđena prisutnost 16 organskih spojeva, od kojih 5 pripada skupini farmaceutika: kofein, 22-trikozanoična kiselina, 4-metiltiomorfolin-1,1-dioksid, 2,6,10,14-heksadekatetraen-1-ol, 3,7,11,15-tetrametil-, acetat, (E,E,E)-, 1,2 bis(trimetilsilil)benzen. Primjenom softverskog paketa STAN provedena je analiza tokova materijala i supstanci i realizirano je modeliranje scenarija radi procjene učinkovitosti selektiranih tehnologija za tretman procjednih voda s gledišta redukcije koncentracije stimulansa kofeina. Tehnologije za tretman procjednih voda koje su razmatrane u sklopu Scenarija 1 su hibridni sustav mokrih polja, membranski bioreaktor (MBR) i reverzna osmoza (RO). Rezultati modeliranja pokazali su visoku učinkovitost redukcije koncentracije kofeina, u vrijedosti od 99.99 %.
