Title: | Experimental study on the biodegradability of substances priority / hazardous from wastewater, in order to establish the admissibility limits in biological treatment plants | Authors: | Taralunga, Maria | Keywords: | Biodegradability;Substances priority;Wastewater;Biological treatment;Plants | Issue Date: | 2008 | Abstract: | The project objective is to establish the dynamics of biodegradation of substances priority / hazardous (trichlorethylene, perchlorethylene, 1,2,4 trichlorobenzene and hexachlorobutadiene) in order to establish the admissibility limits in biological treatment plants for biological treatment. The experiments were conducted on plants micropilot continuous flow, single-stage aeration, and sludge recirculation from the settling in the secondary (similarly to biological industry). Based on the results obtained in the first stage of batch experiments, laboratory experiments were carried out at three contact times, TRH = 16h, 12h and 10h. The conclusion of experiments in micropilot continuous flow installations is that it wastewater containing the trichlorethylene (0.3 g/l), perchloroethylene (0.05 g/l), hexachlorobutadiene (0.003 g /l), 1,2,4 trichlorobenzene ( 0.015 g /l) may be placed in the biological stage of a biological wastewater treatment plants. |
