Abstract
Rudnik Mežica u Sloveniji je značajan antropogeni izvor onečišćenja teškim metalima poput olova i cinka. U povijesti je rudnik bio važan u pogledu ekonomskog razvoja toga kraja zapošljavajući većinu lokalnog stanovništva u eksploataciji i preradi rude za dobivanje olova i cinka. Samo područje rudnika se nalazi u krajoliku bogatom prirodnim dobrima, s obiljem podzemnih i površinskih voda. Geološke karakteristike područja na kojem se rudnik nalazio su takve da se onečišćenje prilikom eksploatacije rude, tijekom i nakon završetka rada rudnika, u velikoj količini proširilo na okolna područja. Klimatski uvjeti i otjecanje površinskih voda uzrokovale su eroziju tla i migraciju onečišćenja teškim metalima u dolinu prema rijekama i podzemnim vodama. Stoga je nužno pronaći efikasnu i ekonomski isplativu metodu njihovog uklanjanja iz procjednih voda. U ovom radu je provedeno preliminarno ispitivanje obrade simulirane procjedne vode onečišćenog dobivenog s Geološkog zavoda Slovenije s prirodnim zeolitom. Ispiranjem tla dobivena je procjeadna voda koja sadrži cink, olovo i mangan pri čemu je najveća koncentracija cinka i mangana dobivena u kiselom mediju pri pH=3,06, što se pripisuje otapanju tla. Koncentracija olova je najviša u blago kiselom mediju i prekoračuje vrijednosti za ispust u vode u prirodi. Obradom dobivene procjedne vode prirodnim zeolitom ustanovljeno je potpuno uklanjanje olova za sve pH vrijednosti otopine. Cink se uklanja maksimalno do 46 %, dok koncentracija mangana raste.
Abstract (english)
The Mežica mine is important anthropogenic source of heavy metal pollution of environment, particularly lead and zinc. Through history mine was important from economic aspect and employed mostly local people in exploitation of raw materials for lead and zinc production. Mine area is located in surrounding rich with natural goods, with many underground and ground water streams. Geological characteristics of the mine area enable spreading of the pollution during exploitation and after closing of the mine activities. Climate conditions and surface water streams caused erosion and migration of pollutants, particularly lead and zinc, towards valley, rivers and underground waters. Due to all these reasons is necessary to find out effective method for their removal from wastewaters produced by soil leaching. In this thesis is examined preliminary treatment of the leachate of the contaminated soil using natural zeolite. Contaminated soil is supplied from Geological Survey of Slovenia. By leaching experiment in laboratory was produced wastewater containing zinc, lead and manganese. The highest concentration of zinc and manganese is obtained at pH 3.06, due to solubility of soil. Concentration of lead is highest in weak acid medium and higher than value allowed for discharge into natural waters. Treatment of produced leachate by natural zeolite enabled complete removal of lead for all examined pH values. Zinc is removed up to 46%, while manganese concentration increases during zeolite treatment.
