Abstract:Izcedne vode predstavljajo nevarnost za okolje, ker vsebujejo veliko organskih in anorganskih komponent, kot so težke kovine. Predmet našega diplomskega dela je bila izcedna voda iz odlagališča za nenevarne odpadke CERO Gajke Ptuj. Izhajali smo iz poročila o obratovalnem monitoringu za leto 2010 in ugotovili, da od težkih kovin presega zakonsko predpisano mejno vrednost celotni krom. Prav tako od merjenih parametrov zasledimo še visoke vrednosti kemijske in biokemijske potrebe po kisiku. Tako so potrebni številni fizikalno–kemijski postopki za odstranjevanja le–teh. Za zmanjševanje koncentracije kroma v izcedni vodi smo uporabili dve metodi: koagulacijo s flokulacijo ter adsorpcijo na zeolite in kelatni polimer. Kot koagulante smo preizkušali aluminijev hidroksid, železov (III) klorid in aluminijev sulfat, kot flokulant pa anionski polielektrolit s tržnim imenom Magnafloc LT 25. V laboratorijskem merilu smo na realnem vzorcu testirali različne dodatke v različnih razmerjih. Iz analize koncentracije kroma v izcedni vodi smo pred in po obdelavi ocenili najustreznejše količine dodatkov. Ocenili pa smo tudi vpliv koagulacije s flokulacijo na zmanjšanje vrednosti KPK in BPK.

Title:CHROMIUM REMOVAL FROM LANDFILL LEACHATE BY COAGULATION AND ADSORPTION PROCESSES
Abstract:Landfill leachates pose a threat for the environment, because they contain many organic and inorganic components, such as heavy metals. In order to find out the quality of leachate from the CERO Gajke Ptuj landfill, operational monitoring report for the year 2010 was examined. We found out that among parameters total chromium, COD and BOD5 exceed discharge limit values. Thus, appropriate treatment is needed for their removal from leachate. Two methods were chosen for the chromium reduction: coagulation with flocculation and adsorption processes on zeolites and chelating polymer. The tested coagulants were: FeCl3, Al2(SO4)3 and Al(OH)3, while anionic polyelectrolyte with trade name Magnafloc LT 25 was used as a flocculant. The laboratory tests were performed. Based on the physicochemical analysis of total chromium concentrations before and after the treatment the most appropriate method was assessed.
Keywords:coagulation, flocculation, adsorption, landfill leachates, chromium
