Abstract

U ovom diplomskom radu prikazan je postupak modeliranja nastajanja procjednih voda u odlagalištu komunalnog otpada programskim paketom VHELP. Kao podloga za model korišten je poprečni presjek odlagališta komunalnog otpada Totovec kojim upravlja gradsko komunalno poduzeće Čakom d.o.o. iz Čakovca.
Programskim paketom Visual HELP provedene su analize osjetljivosti izlaznih parametara (količine nastalih procjednih voda) s obzirom na kvalitetu ugradnje geomembrane u gornjem brtvenom sloju i s obzirom na koeficijent propusnosti odloženog otpada. Rezultati modeliranja ukazuju na važnost kvalitete ugradnje geosintetika budući da su analize pokazale da će u slučaju loše ugradnje nastati bitno veće količine procjednih voda.
Povećane količine procjednih voda predstavljaju značajan pritisak na okoliš i povećavaju rizik od zagađenja. Također ne treba zanemariti i ekonomski aspekt zbrinjavanja povećane količine procjednih voda što u konačnici može dovesti do povećanja cijene zbrinjavanja otpada za krajnjeg korisnika.

Abstract (english)

This master thesis presents the procedure of modelling the formation of leachate from a municipal waste landfill by using a software package VHELP. The cross section of the Totovec municipal waste landfill was used as a basis for the model, which is managed by the joint-stock utility company Čakom from Čakovec.
The Visual HELP software package performed sensitivity analyses of the output parameters (quantities of generated leachate) with regard to the quality of a geo membrane installation in an upper sealing layer and with regard to the permeability coefficient of the disposed waste. The modelling results indicate the importance of the quality of geo synthetics installation, since analyses have shown that in the case of poor installation, significantly higher amounts of leachate will occur.
Increased leachate amounts put significant pressure on the environment and increase the risk of pollution. Also, the economic aspect of disposing of the increased amount of leachate should not be neglected, which may ultimately lead to an increase in the cost of waste disposal for the end user.
