Abstract

Odpadne mineralne oljne gošče obdelujemo s pomočjo fizikalnih in kemijskih procesov. Kot primarne separacijske procese smo uporabili zamrzovanje/taljenje in flokulacijo. Postopek smo nadaljevali z ekstrakcijo, centrifugiranjem in filtracijo ter kot končni postopek obdelave uporabili ultrafiltracijo in vakuumsko uparevanje. Pri vsem tem smo upoštevali optimalno temperaturo, tlak in pH vrednost za najučinkovitejšo in ekonomično obdelavo odpadnih mineralnih oljnih gošč. Namen diplomskega dela je bil ločitev oljno - vodne emulzije, z več kot 50% vsebnostjo olja, na oljno in vodno fazo, pri čemer smo se osredotočili na končno kvaliteto in kvantiteto vodne faze. Pri tem smo spremljali nekaj fizikalno-kemijskih parametrov, kot so elementarna koncentracija določena z EDXRF spektrometrom, pH, temperatura, električna prevodnost, kalorična vrednost ter kemijska potreba po kisiku (KPK), biološka potreba po kisiku (BPK) in vsebnost dušika, katere smo merili s pomočjo NANOCOLOR® fotometra in primerjali ustreznost s predpisanimi mejnimi vrednostmi, ki so v veljavi v Sloveniji. Pri tem smo ugotovili, da so ti parametri dosegli najboljšo vrednost pri končni obdelavi vodne faze oljno - vodne emulzije z vakuumskim uparevanjem.

Secondary title:	PHYSICO-CHEMICAL TREATMENT OF WASTE MINERAL OIL SLUDGE
Secondary abstract:	Waste mineral oil sludge is treated by using a physical and chemical processes. As the primary separation processes, we used the freeze/thaw and flocculation. The procedure was continued by extraction, centrifugation and filtration and as a final processing we used ultrafiltration and vacuum evaporation. In all of this we take account of the optimal temperature, pressure and pH for a more efficient and economical processing of mineral waste oil sludge. The main purpose of this study was the separation of oil-in-water emulsion, with more than 50% content of oil on oil and the water phase, where the focus was on the final quality and quantity of the aqueous phase. In doing so, we monitored some physico - chemical parameters, to be significant for the release of water on the wastewater treatment plant, such as elemental concentration that was determined by EDXRF spectrometer, pH, temperature, electrical conductivity, calorimetric value and as well chemical oxygen demand (COD), biochemical oxygen demand (BOD) and nitrogen content, which was measured by NANOCOLOR® photometer and compared the adequacy of the statutory limits that apply in Slovenia. In doing so, we found that these parameters achieved the best value in the final processing of the aqueous phase of the oil-in-water emulsion by vacuum evaporation.
