dc.description.abstract | Nitrogen and phosphorus removal from wastewater is a way to avoid eutrophication of water bodies. The most oft en used method for phosphorus removal from wastewater is biological treatment. Under anaerobic conditions, phosphorus-accumulating organisms can accumulate more phosphate than is required for their metabolism processes and cell synthesis. The composition of wastewater may have an important influence on phosphorus biological removal from wastewater. In this study, the composition of wastewater in respect of the readily biodegradable chemical oxygen demand (rbCOD) was investigated. The rbCOD characterises the amount of volatile fatty acids (VFAs) and a readily biodegradable substrate in wastewater, which could be rapidly fermented into VFAs and other fermentation products. | eng |
dc.description.abstract | Nustatyta, kad Vilniaus miesto nuotekose lengvai skaidomos organinės medžiagos sudaro vidutiniškai 12,5 % nuo bendrojo ChDS, o Utenos miesto nuotekose – 18 %. Straipsnyje pateikiamos lengvai skaidomų organinių medžiagų ir bendrojo cheminio deguonies suvartojimo regresinės priklausomybės, iš kurių galima prognozuoti šių medžiagų tarpusavio kitimo tendencijas. Be to, nustatytas lengvai biologiškai skaidomų organinių teršalų poreikis pašalinti 1 mg bendrojo fosforo, kurio vidutinė reikšmė yra 7,2 mg lengvai biologiškai skaidomos ChDS dalies Vilniaus nuotekų valykloje ir 8,8 mg lengvai biologiškai skaidomos ChDS dalies Utenos nuotekų valykloje. | lit |
