Abstract

The raw sewage samples of the investigated municipal sewage plant (sewage flow of about 30,000 m3/d) contained about 10(3) campylobacters/100 ml. The sewage plant reduced 80.8% of organic wastes (COD), 85.0% of colony counts (20 degrees C), 92.5% of total coliforms and 88.0% of campylobacters. The sewage plant effluent contained an average of 1.3 X 10(2) campylobacters/100 ml. About 10(10) campylobacters are discharged with the effluent of the high-output sewage plant into the receiving water every day. No reduction of the indicator bacteria was found in the activated sludge tank, there was, however, a significant reduction (94.5%) of campylobacters. In total, 94 strains were differentiated by biotyping and serotyping. 59.6% were found to be Campylobacter jejuni and 40.4% were Campylobacter coli. 8 Serotypes were found among the C. jejuni strains and 12 among C. coli. The raw sewage of the investigated oxidation pond treatment plant contained an average of 51 campylobacters/100 ml. The sewage plant effluent did not show campylobacters in any case.

摘要

被调查的城市污水处理厂（污水流量约为30000立方米/天）的原污水样本中，每100毫升含有约10³个弯曲杆菌。该污水处理厂减少了80.8%的有机废物（化学需氧量）、85.0%的菌落数（20摄氏度）、92.5%的总大肠菌群以及88.0%的弯曲杆菌。污水处理厂的出水每100毫升平均含有1.3×10²个弯曲杆菌。每天约有10¹⁰个弯曲杆菌随高产量污水处理厂的出水排放到受纳水体中。在活性污泥池中未发现指示菌数量减少，然而，弯曲杆菌数量有显著减少（94.5%）。总共通过生物分型和血清分型鉴别出94株菌株。发现59.6%为空肠弯曲杆菌，40.4%为结肠弯曲杆菌。在空肠弯曲杆菌菌株中发现了8种血清型，在结肠弯曲杆菌中发现了12种血清型。被调查的氧化塘处理厂的原污水中，每100毫升平均含有51个弯曲杆菌。该污水处理厂的出水在任何情况下都未检出弯曲杆菌。
