Sekundarni naslov:	Comparison of vertical and horizontal systems of constructed wetlands
Sekundarni povzetek:	The constructed wetlands (CW) or artificial wetlands with the wastewater treatment as their primary function are complex systems of water, substrate, plants, animals and microorganisms (bacteria). In practice there are two general systems in use, the system with the surface and the system with the subsurface flow, which is further divided into the system with the horizontal water flow and in the system with the vertical water flow. Understanding of constructed wetlands functioning is difficult, as a large number of physical, chemical, and biological processes take place simultaneously and influence each other. Therefore a number of mathematical models have been developed or are being developed which can offer invaluable tool for analyzing, studying and improving understanding of the complex systems such as the constructed wetlands. A design of CW can be based on a number of models, ranging from very simple ones (rules of thumb and regression equations) to firstorder plug-flow models and more complex dynamic models. This thesis presents a comparison between the vertical (V-CW) and the horizontal (H-CW) systems, and the mathematical models, which are most commonly used in practice for the subsurface water flow CWs, such as the empirical rules, the regression equations and the most used first-order plug-flow model (k-C* model).

Povzetek (ePrints):	Rastlinske čistilne naprave (RČN) ali umetna močvirja s primarno funkcijo čiščenja odpadnih voda so kompleksni sistemi vode, substrata, rastlin, živali ter mikroorganizmov (bakterij). V praksi se uporabljata dva splošna sistema, in sicer sistem s površinskim ter sistem s podpovršinskim tokom, ki se nadalje deli na sistem s horizontalnim tokom vode in na sistem z vertikalnim tokom vode. Razumevanje delovanja rastlinskih čistilnih naprav je oteženo zaradi velikega števila fizikalnih, kemijskih in bioloških procesov, ki potekajo sočasno in hkrati vplivajo en na drugega. Zato so bili razviti oziroma se razvijajo številni matematični modeli, ki lahko predstavljajo neprecenljiv pripomoček za analizo, proučevanje in izboljšanje razumevanja kompleksnih sistemov, kot so rastlinske čistilne naprave. Dimenzioniranje RČN je lahko zasnovano po številnih modelih, od zelo enostavnih (empirična pravila in regresijske enačbe), modelov prvega reda cevnega reaktorja ter do bolj kompleksnih, dinamičnih modelov. Diplomska naloga prikazuje primerjavo vertikalnih (V-RČN) in horizontalnih sistemov (HRČN) ter matematične modele, ki se največ uporabljajo v praksi za RČN s podpovršinskim tokom vode, kot so empirična pravila, regresijske enačbe in najbolj uporabljenega modela prvega reda cevnega reaktorja (model k-C*).
