Abstract

U industrijskom postupku proizvodnje drvenjače za dobivanje ambalažnog papira nastaju ogromne količine otpadnih voda. Otpadne vode predstavljaju opasnost po okoliš, a njihovim recikliranjem, suspendirani organski i anorganski spojevi, te bakterije se koncentriraju i pri ponovnom korištenju otpadnih voda mogu uzrokovati propadanje i neugodne mirise papira. Ovim radom ispitana su svojstva otpadne vode industrije papira uz primjenu zeolita (NZ Hrvatska, NZ Turska, NZ Turska izmijenjen s magnezijem, NZ Srbija, NZ Srbija izmijenjen s magnezijem, Terrana, Terrana izmijenjen s magnezijem i zeolit A Slovenija) i gline (glina Hrvatska) za uklanjanje suspendiranih tvari. Korišteni su uzorci otpadnih voda tvornice Drvenjaca d.d. Fužine, prethodno obradeni koagulantom (EP-10) i anionskim flokulansom (A-45). Vrijednosti određivanih parametara (pH, mutnoca, boja, te broj bakterija) ukazuju na to da se obradom otpadnih voda zeolitom Terrana može postići najbolji stupanj uklanjanja suspendiranih tvari. Trebalo bi ukloniti i bakterije koje su u velikom broju prisutne u otpadnim vodama. Time bi se omogućilo uspješno recikliranje otpadnih voda, čime se postiže zaštita okoliša, a dobiveni papir je kvalitetan ambalažni materijal.

Abstract (english)

In the industrial process of the packing paper production from the wood pulp, the huge quantities of the waste water are produced. The waste waters are very dangerous for the environment, but recycling of water can increase the concentration of organic and inorganic substances and bacteria, which lead to corrosion and odours of paper during the re-use of water. In this paper the properties of waste water from the paper industry using the zeolites (NZ Croatia, NZ Turkey, NZ Turkey exchanged with magnesium, NZ Serbia, NZ Serbia exchanged with magnesium, Terrana, Terrana exchanged with magnesium and zeolite A Slovenia) and clay (clay Croatia) for the removal of the suspended substances were investigated. The samples of waste water were from Factory Drvenjaca, Fužine, previously treated with coagulant (EP-10) and anionic flocculant (A-45). Values of parameters determined (pH, turbidity, color and number of bacteria) have showed that by treatment of waste water samples with zeolite Terrana, can be achieved the best level of suspended substances removal. The bacteria, present in great number in the waste water, should be removed, too. With these processes it would be possible to achieve successful recycling of waste waters, protecting the environment, as well as getting the packing paper of great quality.
