dc.description.abstractLow concentration of chlorinated aliphatic compounds may be found in wastewater and contaminated soils from different industrial sources and in the air arisen from these type sources. Low levels of Volatile Organic Compounds (VOC)'s could be removed by adsorption, incineration or biofiltration methods. These methods have some disadvantages with low removal efficiency or high operation cost. Chlorine has been removed from the chlorinated aliphatic compounds by biological methods at anaerobic conditions. The aim of this research was investigation of biological treatment of VOC's in high flow speed reactors. Resistance capacity of micro-organisms was investigated in an upflow anaerobic sludge bed reactors (UASB) designed with automate control system by feeding with addition co-substrate, loading different ratio of organic matter, hydraulic retention time (HRT), at stable condition of COD, Volatile Fatty Acids (VFA), pH, alkalinity, temperature (35C°) etc. during the anaerobic treatment. In this research, the removal of DCM and PCE were approximately 60-70% and 98%. The removal of COD for DCM and PCE were approximately 75.5% and 97.4%. The decomposition ratios were calculated for DCM and PCE as 0.136 mg /gVSS.d and 0.305 mg /gVSS.d respectively. The highest methane ratio in the biogas production was 64% with DCM decomposition. Also inhibition concentrations for DCM and PCE (IC) in 24 hour were determinated as IC50; 42.6 and IC25; 16.8 and IC50; 24.9 and IC25; 6.7. The highest methane ratios in the obtained biogas were 64% for DCM, 82.8% for PCE. © 2006. International Scientific Conference SGEM.en_US
