In the investigations carried out on anaerobic biodegradation of pesticides, specific sludge activity and toxity of pesticides in batch tests were determined.The specific methanogenic sludge activity was deterined i.e. the amount of acetate as an amount of COD for methane production per gam of sludge VSS (voatile suspended solid) per 1 day. Using the toxity test the magnitude of inhibition caused by presence of Metaxychlor - organochlorine insecticide group of pesticides - was assessed.The laboratory model of UASB was used for sludge cultivtion ((for methanogenic activity tests).Total voume of the reactor was 6.4 l.A portion of digested sludge taken from a Myslenice municipal wastewater treatment plant was used as an inoculum.
