Abstract:
Namen diplomske naloge je izboljšati kakovost odpadne vode iz kovinske industrije z uporabo koagulacije. Raziskovali smo učinkovitost zniževanja vrednosti kemijske potrebe po kisiku (KPK) z enim od treh izbranih koagulantov PACl, FeCl3 in Al2(SO4)3 v kombinaciji z enim od dveh flokulantov Amerfloc 425 in Amerfloc 487. Analizirali smo vrednosti pH, SAK, prevodnost, motnost, KPK in vsebnost anionskih tenzidov. Odvzeli smo tri različne vzorce odpadne vode z različnimi začetnimi vrednostmi KPK. Najboljša kombinacija se je izkazala s PACl v kombinaciji z Amerflocom 487. Vrednost KPK smo znižali pod 150 mg/L O2, kar znaša čez 80 %, s čimer je omogočen izpust čiščene vode v vodotoke.

Title:
COAGULATION OF INDUSTRIAL WASTEWATER WITH NOVEL POLYMERS
Abstract:
The aim of diploma thesis was to improve the quality of wastewater from metal industry. Three different coagulnts PACl, FeCl3, Al2(SO4)3, and two different polymers Amerfloc 425 and Amerfloc 487 were chosen. The combination of selected chemicals were tested in order to decrease chemical oxygen demand (COD). We analyzed the pH, spectral absorption coefficient at 254 nm, conductivity, COD, turbidity and the anionic surfactants content in waste water. The combination of PACl and Amerfloc 487 was the most successfull in COD removal. We managed to lower COD below 150 mg/L O2, which means above 80 % removal efficiency. The treated wastewater could be released into environement.
