Abstract:
Centralna čistilna Novo mesto, s tehnologijo konvencionalnega čiščenja, že dolgo ni več zagotavljala dovolj učinkovito čiščenje, zato so med leti 2011 in 2013 zgradili sodobno z membranskim bioreaktorjem (MBR). Z ultrafiltracijskimi membranami so se iz odpadne vode odstranili tudi virusi in bakterije, kar je zelo pomembno za izpust vode v reko Krko, saj se v njej kopajo ljudje. Po čiščenju odpadne vode z MBR je voda mikrobiološko neoporečna in nastane bistveno manj blata kot pri klasični tehnologiji. Spremljali smo učinkovitost čiščenja odpadne vode na stari CČN in novi CČN z MBR. Z analizami odpadne vode na vtoku in iztoku v novi CČN smo določali vrednost parametrov KPK, BPK5, amonijevega dušika, celotnega fosforja, celotnega dušika in neraztopljenih snovi ter ugotavljali, ali so rezultati v skladu z zakonodajo. Rezultati analiz parametrov so pokazali bistveno boljše rezultate pri čiščenju odpadnih voda z MBR, kot pa pri klasični, konvencionalni tehnologiji. Naredili smo tudi primerjavo med vrednostmi parametrov in učinkovitostjo čiščenja odpadne vode v času obratovanja stare in sodobne CČN.

Title:
URBAN WASTEWATER TREATMENT WITH MEMBRANE BIOREACTOR
Abstract:
With conventional technology, the wastewater treatment plant of Novo mesto has not guaranteed efficient treatment. Therefore, a modern version was built with a membrane bioreactor (MBR), during the period 2011 and 2013. With its ultrafiltration membranes, bacteria and viruses were also removed from the waste water, which is important the water discharge into the river Krka where some people bath. After cleaning the waste water with MBR, the water is microbiologically wholesome and there is a considerable decrease of excess sludge compared to classical technology. We have been monitoring the efficiency of treating waste water with the old treatment plant as well as the new MBR one. With the analyses of waste waters on the flow and outflow in the new treatment plant, parameters COD, BOD5, ammonium nitrogen, total phosphorous, total nitrogen as well as suspended matter were determined. Further, we established, whether the results were in accordance with the legislation. The results of the analyses for each parameter have shown considerably better results when treating waste water with MBR compared with classical, conventional technology. We have also made a comparison of the parameters and their removal efficiencies between the old and new water treatment plant.
