Abstract
Svakodnevna emisija teških metala u okoliš rezultat je čovjekovog djelovanja, najčešće industrije, rudarenja, neadekvatnog zbrinjavanja i spaljivanja otpada te primjene pesticida i umjetnih gnojiva. Takvi antropogeni izvori značajno onečišćuju vode u prirodi te je nužno pronaći ekološki i ekonomski prikladnu metodu uklanjanja teških metala iz voda. U ovome diplomskom radu ispitana je mogućnost korištenja čvrstog otpada/nusproizvoda (koštice maslina, pelet od komine maslina, ostaci... More hridinskog ježinca, koštice trešanja i koštice višanja) iz lokalnih pogona za proizvodnju i preradu hrane kao biosorbenasa u obradi otpadne vode onečišćene cinkom (c o = 193,9 mg/L). Sorpcija cinka provedena je šaržnim postupkom u trajanju od 24 h, pri omjerima kruto/tekuće u rasponu S/L = 0,25/50 ‒ 2,5/50. Svi ispitani biosorbensi pokazali su određeni potencijal za pročišćavanje voda onečišćenih cinkom. Najveća učinkovitost uklanjanja za sve biosorbense postignuta je pri najvećem S/L omjeru od 2,5/50; kako slijedi: 69,5% za koštice višanja, 46,8% za koštice maslina, 35,8% za ostatke hridinskog ježinca, 29,0% za pelet od komine maslina te 26,8% za koštice trešanja. Unatoč visokoj učinkovitosti uklanjanja od ≈ 70% na košticama višanja, zaostala koncentracija cinka od 59,1 mg/L veća je od maksimalno dopuštene koncentracije od 2 mg/L propisane pravilnikom, za ispust obrađene vode u sustav javne odvodnje i u prirodne recipijente. Buduća istraživanja trebalo bi usmjeriti na smanjenje koncentracije cinka do zakonom propisanih vrijednosti. Uporabom čvrstog otpada/nusproizvoda u navedenu svrhu smanjila bi se njegova izvorna količina koja bi neiskorištena mogla završiti na odlagalištu, a spaljivanjem zasićenih biosorbenasa u kontroliranim uvjetima omogućilo bi se dobivanje energije iz otpada. Takav način iskorištenja otpada smanjio bi ukupne troškove obrade voda te pridonio načelima održivog razvoja i zero-waste. Less
Abstract (english)
The daily emission of heavy metals into the environment is the result of human activity, most often industry, mining, inadequate disposal and waste incineration, as well as application of pesticides and artificial fertilizers. Such anthropogenic sources significantly pollute water in nature, therefore is necessary to find an ecologically and economically suitable method for heavy metals removal from water. In this diploma thesis, the possibility of using solid waste/by-products... More (olive pits, olive pomace pellets, remains of sea urchin, cherry pits and sour cherry pits) from local plants for food production and processing as biosorbents in the treatment of wastewater contaminated with zinc (co = 193.9 mg/L) was investigated. Zinc sorption was carried out by a batch process during 24 h, with solid/liquid ratios in the range S/L = 0.25/50 - 2.5/50. All tested biosorbents showed a certain potential for purifying zinc-contaminated water. The highest removal efficiency for all biosorbents was achieved at the highest S/L ratio of 2.5/50, as follows: 69.5% for cherry pits, 46.8% for olive pits, 35.8% for the remains of sea urchin, 29.0% for olive pomace pellets and 26.8% for cherry pits. Despite the high removal efficiency of ≈ 70% on cherry pits, the residual zinc concentration of 59.1 mg/L is higher than the maximum permissible concentration of 2 mg/L, according to the Croatian legislation for the discharge of treated water into the public sewage system and into natural recipients. Future research should be focused on reducing zinc concentration below the prescribed value. Using solid waste/by-products for the stated purpose would reduce its original amount that could end up in a landfill, and by burning saturated biosorbents under controlled conditions, it would be possible to obtain energy from waste. Such a way of using waste would reduce the total costs of water treatment and contribute to the principles of sustainable development and zero waste. Less
