Povzetek

Namen naloge je bil, vzporedno z dvema različnima vrstama kemikalij, izvesti postopek fizikalno-kemijskega čiščenja vzorca tehnološke odpadne vode podjetja KK najprej laboratorijsko in nato, glede na rezultate, še na obstoječi čistilni napravi. Učinkovitost čiščenja s kombinacijo anorganskega koagulanta Al2(SO4)3 in polielektrolita Magnafloc E24 smo primerjali s kombinacijo polihidroksialuminijevega klorida (PAC) in flokulanta Nalco 77171. Rezultati čiščenja so pokazali, da je potrebno dodati nižje količine PAC glede na Al2(SO4)3. Povprečna poraba Al2(SO4)3 na šaržo je znašala ca. 135 L, poraba PAC pa 45 L, medtem ko je poraba polielektrolita Magnafloc E 24 znašala ca. 37 L na šaržo, poraba Nalca 77171 pa 7 L, kar je za 80 % manj. Zmanjšale so se vsebnosti sulfata in cinka. Ekonomski izračun je pokazal, da je cena predlaganega fizikalno-kemijskega čiščenja štirikrat dražja od obstoječega čiščenja zaradi uporabe bistveno dražjih kemikalij.

Sekundarni povzetek:	The intention of this work was to compare two different waste water treatments (mechanical/chemical). The samples of he waste water were taken from current production in KK company. The treatment was first carried out in laboratory and afterwards in the production itself on the existing waste water treatment plant. The first method of treatment was the combination of inorganic coagulant Al2(SO4)3 and polyelectrolyte Magnafloc E24. The second method was the use of poly hydroxyl aluminum chloride (PAC) and flocking agent Nalco 77171. The next step was the comparative analysis between those two methods. The results indicated that the second method was more effective than the first one due to the consumption of chemicals used. The amount of chemicals used in the second method was lower for more than 80 % then in the first method. The average use of PAC per one cleaning cycle was 45 L, while the amount of Al2(SO4)3 was 135 L. The average consumption of polyelectrolyte Magnafloc E24 was 37 L per cleaning cycle and consumption of Nalco 77171 was only 7 L. The second method also showed the reduction of sulfate and zinc presence. However the economical calculation revealed higher costs for the second, more effective method for more than 4 times than the existing waste water treatment (first method),due to high prices.
