Abstract

The efficiency of anaerobic treatment of animal wastes and aerobic treatment of urban sewage in removing faecal coliforms and their effect on the antibiotic-resistant coliforms was evaluated in this study. A two reactor anaerobic digester and six activated sludge plants were studied. The concentrations of both faecal coliforms in sampling from influents and treated effluents were calculated to determine efficiency of plants during depuration treatments. Anaerobic and aerobic treatments resulted in 90% and 97% (arithmetic mean values) efficiency in removing faecal coliforms. Although neither anaerobic nor aerobic treatment seems to significantly increase the percentage of antibiotic-resistant bacteria, during the aerobic treatment of urban sewage there was a tendency for the percent of antibiotic-resistant bacteria to increase.

摘要

本研究评估了动物粪便厌氧处理和城市污水好氧处理去除粪大肠菌群的效率及其对抗生素抗性大肠菌群的影响。研究了一个双反应器厌氧消化池和六个活性污泥处理厂。通过计算进水和处理后出水样本中粪大肠菌群的浓度，以确定各处理厂在净化处理过程中的效率。厌氧处理和好氧处理去除粪大肠菌群的效率分别为90%和97%（算术平均值）。虽然厌氧处理和好氧处理似乎都不会显著增加抗生素抗性细菌的比例，但在城市污水好氧处理过程中，抗生素抗性细菌的比例有增加的趋势。
