Waste effluents in wood industry contain very high portion of dangerous and toxic substance - formaldehyde. That is why it is inevitably vital to start with detailed analysis of waste effluents and with studies of possibilities of decontamination. Statistical analysis are showing that wood industry are not well aware of the fact how quickly the ecological balance can be destroyed, since the quantitiesof treated waste effluents are extremely low. During the seminar some guidelines on how to extract formaldehyde from waste effluents were issued with the stress on secundar method of treatment - biological treatment of waste effluents. Biological treatment can be both, aerobic or anaerobic. During the seminar both methods were introduced with theemphasis on the aerobic procedure, which I was researching in the experimental part of my diploma workLesna industrija ni velik onesnaževalec voda, a s tem se ni tolažiti. Odpadne vode lesne industrije pogosto vsebujejo zelo visoke vrednosti nevarne in strupene substance - formaldehida, zato je nujno potrebno, da se prične s podrobnimi analizami odpadnih voda in z raziskavami o možnostih čiščenja. Statistične analize so pokazale, da se lesna industrija še vse premalo zaveda kako hitro lahko porušimo ekološko ravnotežje v naravi, saj so vrednosti o količini čiščenih odpadnih voda v lesni industriji izjemno nizke. Tako smo v seminarju podali nekaj smernic in možnosti odstranjevanja formaldehida iz odpadnih voda s poudarkom na sekundarnem postopku čiščenja - biološkem čiščenju odpadnih voda. Biološko čiščenje je lahko anaerobno ali aerobno, zato smo predstavili oba postopka. Večji poudarek in podrobnejši opis je podan za aerobni postopek biološkega čiščenja, na katerem sem opravila svoje raziskave v praktičnem delu diplomske nalogeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza lesarjev Slovenije
