영문 초록

To estimate pollution status of livestock wastewater on four piggeries and one abattor in Taegu area, physicochemical water analysis such as pH, suspeded solid(SS), biochemical oxygen demand(COD) and chemical oxygen demand(COD), and bacteriological examiantions such as number of total viable cells and number of coliform with or without antibiotic resistance were carried out. The results obtained were as follows: The pH values of raw sewage ranged from 9.0 to 7.2 that of the effluent treated was lowed to 5.6-7.7. The SS valused of raw sewage ranged from 5,275ppm to 120ppm that of the effluent decreased to 162ppm-30ppm. The BOD values of raw sewage ranged from 6,200ppm to 120ppm that of the effluent treated decreased to 111ppm-80ppm. The COD values of raw sewage ranged from 5,725ppm to 298ppm that of the effluent decreased to 137ppm-76ppm. The total viable cells of raw sewage ranged from 8.5×10¹¹/ml to 9.9×10⁷/ml, those of the effluent decreased to 5.6×10⁵/ml-4.2×10⁸/ml. The total coliforms of raw sewage ranged from 5.5×10⁹/ml to 1.3×10⁵/ml, those of the effluent decreased to 3.6×10⁴/ml-9.0×10⁶/ml. The incidence of streptomycin resistant coliforms was the highest(1.8-66.7%), and followed by tetracycline(1.7-64%), kanmycin(9.3-50.1%), ampicillin(0.06-45.4%) and chloramphenicol(14.3-33.5%) to total coliforms of raw sewage. The incidence of antibiotic resistant coliforms of sewage In farms ranged from 3.4-66.7% and that of abattoir’s was 0.06% to 14.3%. Antibiotic resistant coliform counts of raw sewage ranged from 1.3×10⁸/ml to 3.9x/10³/ml, those of the effluent decreased to 3.0×10¹/ml-2.3×10⁵/ml.
