V diplomski nalogi je obravnavano odvajanje in čiščenje fekalnih odpadnih voda v vaseh Jezero, Lukovek in Dolenja Dobrava v občini Trebnje. V primeru goste poseljenosti je najprimernejša izgradnja javnega komunalnega sistema s skupno malo čistilno napravo (MČN), drugače se izven območij aglomeracij uporabijo individualne MČN ali pa skupni sistemi v zasebni lasti. Na začetku diplomske naloge je navedena zakonodaja, ki je povezana z malimi čistilnimi napravami. Nadalje so predstavljeni kanalizacijski sistem in pripadajoči objekti. Odpadne vode lahko v MČN očistimo na več načinov in pri tem uporabimo postopke, ki so opisani v nalogi. Predstavljene so tudi male čistilne naprave, ki temeljijo na mehanskem in biološkem čiščenju ter MČN s pritrjeno biomaso in z aktivnim blatom. Na koncu je prikazana stroškovna primerjava treh variantnih rešitev, in sicer z eno skupno MČN, vsaka vas s svojo MČN in individualnimi MČN. Dokazano je, da so individualni sistemi najcenejši, razen na območjih aglomeracije, kjer so obvezni kanalizacijski sistemi z MČN.

Abstract

Graduation thesis discusses faecal wastewater drainage and treatment in villages Jezero, Lukovek and Dolenja Dobrava in municipality Trebnje. In case of a high population density the most suitable is the construction of a public sewerage system with a common small treatment plant (further STP). Outside of agglomeration area, individual STPs or private common systems are used. At the beginning of the graduation thesis the legislation regarding the STPs is presented. Further on, a sewerage system with the corresponding objects is described. Wastewater can be treated in STP in various ways with the usage of procedures described in the thesis. STPs based on mechanic and biological treatment and STPs with fixed-film or attached growth systems and activated sludge are also described. At the end of the thesis a cost comparison of three possible solutions is presented; one common STP, each village with its own STP or individual STPs. As it is shown, the individual systems are the cheapest, except in the agglomeration areas where sewerage systems with STPs are mandatory.
