Abstract
The article presents the results of organoleptic and physicochemical analysis of waste water from poultry enterprises after passing through a shungite filter. The efficiency of using a filter based on shungite for purification and disinfection of wastewater is shown. The elimination of an unpleasant odor, a several-fold decrease in indices for turbidity, color, oxidizability, and biochemical oxygen consumption were recorded. The amount of lead decrease by 42.2 was noted; manganese – 34.2; copper – 74,1; zinc – 83,6 % (P<0.001); sulfates – 19,5 % (P<0,05); chlorides – 90,6 %; phosphates - by 44,8 % (P<0.001). The amount of ammonia in waste water with a significant excess of this indicator in the starting material after filtration decreased by 2,5 times (P<0.001).
