20.500.12556/DKUM-27410 The use of constructed wetland for dye-rich textile wastewater treatment The objective of the present paper was to examine the treatment efficiency of constructed wetlands (CW) for the dye-rich textile wastewater with special focus on colour reduction. Preliminary, a series of dynamic experiments were performed in the CW model packed with gravel, sand, and zeolitic tuff on three synthetically-prepared wastewaters using chemically differ dyestuffs, auxiliaries and chemicals, in order to investigate the potential of low-cost materials as media for textile dye-bath wastewater treatment. The obtained results evidence that applied CW model reduces colour by up to 70%, and COD and TOC by up to 45%. Based on these results, the pilot CW with vertical (VF) and horizontal flow (HF) was constructed near textile factory mainly for cotton and cotton/PES processing with intention to treat real textile wastewater in-situ. It was designed for 1 m3/d, covering 80 m2, packed with sand and gravel, and planted with Phragmites australis. The average treatment efficiency of the CW for the selected pollution parameters were: COD 84%, BOD5 66%, TOC 89%, Ntotal 52%, Norganic 87%, NH4-N -331%, sulphate 88%, anion surfactant 80%, total suspended solids (TSS) 93%, and colour 90%, respectively. The results unequivocally proved that the CW could offer an optimal solution to meet the environmental legislation as well as requirements for effective and inexpensive textile wastewater treatment. coloured textile wastewater constructed wetland Phragmites australis true false false Angleški jezik Angleški jezik Neznano 2012-06-01 11:00:19 2012-06-01 11:00:21 2022-04-15 03:44:21 2019-07-10 12:16:38 2008 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 628.3:677.11 12026390 0304-3894 URN:SI:UM:DK:MAVY9FYY http://dx.doi.org/10.1016/j.jhazmat.2007.11.068 1 https://dk.um.si/Dokument.php?lang=slv&id=36706 Fakulteta za strojništvo 0 0 0
