20.500.12556/DKUM-38510 KAKOVOST ODPADNIH VOD IZ ČISTILNE NAPRAVE PODJETJA PALOMA EFFLUENT QUALITY OF PALOMA WASTEWATER TREATMENT PLANT V diplomski nalogi smo preučevali kakovost odpadnih vod iz čistilne naprave podjetja Paloma. V podjetju so se pred izgradnjo čistilne naprave zaradi čezmernega onesnaževanja voda in negativnih vplivov na okolje, ki ga povzroča papirna industrija, soočali z vse večjimi pritiski slovenske in evropske zakonodaje. Kakovost odpadne vode na iztoku iz čistilne naprave smo primerjali s kakovostjo odpadne vode, ki se je pred izgradnjo stekala v reko Muro. Odpadna voda je vsebovala zelo visoke vrednosti neraztopljenih in usedljivih snovi, KPK in BPK5. Ti parametri so pred izgradnjo čezmerno obremenjevali okolje. Na vtoku in iztoku iz čistilne naprave smo opravili analize štirikrat v mesecu, od marca do junija, in jih primerjali z monitoringi za leti 2001 in 2002, to je pred izgradnjo čistilne naprave. V letu 2001 so se odpadne vode iztekale še neposredno v vodotok, oktobra leta 2002 pa se je vzpostavil mehansko - kemijski del in s tem začetek delovanja čistilne naprave. Meseca marca, leta 2003, je začela obratovati celotna čistilna naprava, s priključitvijo biološkega dela. Opravili smo analize pH, temperature, neraztopljenih snovi, usedljivih snovi, celotnega fosforja, amonijevega in celotnega dušika, KPK in BPK5 in jih primerjali z letom 2001 in letom 2002. Na osnovi rezultatov smo ugotovili, da je učinkovitost čistilne naprave in kakovost odpadne vode na iztoku zelo visoka, glede na vhodne obremenitve. V merjenem obdobju smo dosegali visoke učinke čiščenja in sicer v povprečju 97,08 % za KPK in 98,98 % za neraztopljene snovi. Učinek čiščenja po usedljivih snoveh je skoraj 100 %. Visoke vrednosti parametrov (neraztopljene snovi, usedljivost snovi, KPK in BPK5), ki so presegali zakonsko mejno vrednost za več kot 100 %, so padle pod mejne vrednosti slovenske in evropske zakonodaje. Z izgradnjo čistilne naprave je podjetje Paloma zmanjšalo negativne vplive na okolje, izboljšalo kakovost reke Mure, življenje okoliških prebivalcev ter prispevalo k ohranjanju naravnih virov in biotske raznolikosti. In the diploma paper the quality of the wastewater treatment plant (WWTP) of the company Paloma was studied. Prior to the construction of the WWTP, the company was confronted with the increasing pressures of Slovenian and European legislation, due to excessive water pollution and negative environmental impacts caused by the paper industry. The quality of effluent from the WWTP was compared with the quality of waste water, which flew to the river Mura prior to the construction of the WWTP. The waste water contained very high levels of insoluble and settleable solids, COD and BOD5. These parameters excessively polluted the environment prior to the construction. The analyses at the inflow and outflow from the WWTP were performed four times a month, from March until June, and compared to the monitoring for the years 2001 and 2002 carried out prior to the construction of the WWTP. In 2001, the waste water flowed directly into the river; in October 2002 a mechanical - chemical part was established, which was the beginning of the WWTP. In March 2003, the entire WWTP started to operate, adding the biological part. pH, temperature, insoluble solids, settleable solids, total phosphorus, ammonium and total nitrogen, COD and BOD5 were determined in 2011 and were compared to 2001 and 2002. Based on the results, it has been found that the effectiveness of the WWTP and effluent quality in the outflow is very high, regarding the input load. During the measuring period, high removal efficiencies were achieved; on average 97.08 % for COD and 98.98 % for insoluble solids. Removal efficiency of insoluble solids was determined at almost 100 %. High values of the parameters (insoluble solids, settleable solids, COD and BOD5), which exceeded the emission limit values for more than 100 %, fell bellow the maximum allowed values defined by the Slovenian and European legislations. With the construction of the WWTP the company Paloma reduced negative impacts on the environment by improving the quality of the river Mura and life of local residents and contribute to conservation of the natural resources and biological diversity. čistilna naprava papirna industrija emisije v vodotoke wastewater treatment plant pulp and paper industry emmisions into water true true false [N.
