Research of wastewater tertiary treatment


Small individual household wastewater treatment plants not always operate well. Consequently, the concentrations of ammonium nitrogen and phosphate phosphorus are exceeded. The aim of the work was to found the most effective material for wastewater tertiary treatment and propose environmentally friendly ways to solve fresh water problem. Three filter fillings (foam-glass, zeolite and biochar) were tested. As a result, we have got a following conclusion, foam-glass removed phosphate phosphorus most effectively (efficacy – 14−91%) and against ammonium nitrogen, comparatively effective was zeolite (efficacy – 29−100%).

Tretinio nuotekų valymo tyrimai


Individualaus buitinių nuotekų valymo įrenginiai ne visada dirba efektyviai. Dėl to fiksuojami nitratų azoto, amonio azoto, bendrojo azoto, bendrojo fosforo ir fosfatų fosforo koncentracijų išvalytose nuotekose viršijimai. Darbo tikslas surasti efektyvias medžiagas tretiniam nuotekų valymui ir pasiūlyti šiai problemai spręsti aplinkai draugiškas technologijas, kad išvalytos nuotekos nepakenktų aplinkos kokybei. Buvo tirti trys filtro užpildai (pustiklis, ceolitas, bioanglis). Gauti rezultatai ir išvados, kad pustiklis efektyviau (efektyvumas – 14−91%) šalina iš nuotekų fosfatų fosforą, o ceolitas – amonio azotą (efektyvumas – 29−100 %).

Reikšminiai žodžiai: tretinis nuotekų valymas, bendrojo fosforo ir bendrojo azoto valymas, ceolitas, pustiklis, bioanglis.
