Abstract
U ovom radu analizirana je učinkovitost elektrokemijskog procesa (elektrokoagulacije) prilikom pročišćavanja zauljenih otpadnih voda mineralnog porijekla koje se generiraju u postupku pročišćavanja dimnih plinova iz procesa uplinjavanja mulja s uređaja za pročišćavanje otpadnih voda. U svrhu optimizacije procesa u radu je ispitivan utjecaj vrste elektroda (željezo, aluminij, INOX) koje su serijski spojene, vremena reakcije (10-35 minuta) te promjene pH vrijednosti u sirovoj otpadnoj vodi (pH 6 do pH 9) na stupanj uklanjanja pojedinih pokazatelja kakvoće vode. Promatrane vrijednosti su tehnološki parametri (pH vrijednost, električna vodljivost, otopljeni kisik, temperatura, ukupna otopljena tvar (TDS), kemijska potrošnja kisika (KPK)). Rezultati provedenog istraživanja prikazuju učinkovitosti pročišćavanja zauljenih voda promatrajući KPK i TDS te ukazuju na oko 17%- tnu učinkovitost pročišćavanja KPK kod pH vrijednosti 7 s vremenom reakcije od 30 minuta, te oko 56%-tnu učinkovitost pročišćavanja TDS kod pH vrijednosti 9 s dužim vremenom reakcije od 30 minuta.
Abstract (english)
The efficiency of the electrochemical process (electrocoagulation) was analyzed during the treatment of oily wastewater of mineral origin that is generated in the process of the treatment of exhaust gasses from the process of gasification of sewage sludge. In order to optimize the process, this research is focused on the influence of the type of electrodes (iron, aluminum, INOX) connected in series, contact (reaction) time (10-35 minutes) and changes in the pH value of the raw wastewaer from pH 6 to pH 9 on the degree of removal of different water quality parameters. The observed values are the operating parameters (pH value of the raw wastewater, electrical conductivity, dissolved oxygen, temperature, total dissolved matter (TDS), chemical oxygen demand (COD)). The results of this research show the efficiencies of oily water treatment by observing COD and TDS indicating the app. 17% efficiency of COD removal at pH value 7 with a reaction time of 30 minutes, and app 56% efficiency of TDS removal pH value 9 with reaction time of 30 minutes.
