Abstract

Filamentous bacteria and other large microorganisms, which are useful indicators of bulking and poeration, were identified by microscopic observation. Activated sludge samples were taken from the aeration basin of 5 municipal wasterwater plants and 6 industrial ones. Among the filamentous bacteria founds, Microthrix parvicella was most frequently present, followed by type 0041, type 1701 and Nocardia. This frequency of occurrence was similar to those reorted in USA and the Neterland. The morphology of filamentous bacteria observed were generally identical with those previously reported. except type 1701 which had slender filament diameter. Among protozoa, Vorticella was most frequently present, followed by Aspidisca, Opercularia and Difflugia. Philodina was the only metazoa observed. Both filamentous bacteria and protozoa would be useful indicator organisms. The potential for these organisms as indicators were discussed.

슬러지 팽화의 원인이 되며 활성오니 공정운영상의 지표생물이 되는 사상세균과 원생동물을 동정하기 위하여 도시하수 활성오니 처리장 6개소와 산업폐수활성오니 처리장 5개소의 폭기조로부터 시료를 채취하여 현미경 경검법과 일부 생리학적 방법을 써서 미생물을 동정하였다. 가장 많이 출현하였던 사상세균은 Microthrix parvicella이었으며 다음이 type 0041, type 1701, Nocardia의 순이었다. 비록 시료수는 적었지만 이러한 출현빈도는 미국과 네덜란드에서 조사된 것과 비슷한 경향을 보였다. 사상세균의 형태는 이전의 문헌에서 보고된 것과 대체로 일치하였는데 type 1701의 경우에는 전형적인 형태에 비해 사상체(filament)의 직경이 약간 가늘었다. 이러한 사상세균들은 낮은 유기물부하 또는 낮은 DO와 관계가 있는 것들이었으므로 더 많은 조사가 이루어지면 지표생물로서의 활용이 가능할 것이다. 원생동물에 있어서는 Voricella가 가장 많이 출현하였고, 다음이 Aspidisca, Opercularia, Diffugia의 순이었다. 후생동물에 있어서는 Philodina가 유일하게 출현한 속이었다. 이러한 속들은 활성오니성 미생물로서 처리상황이 좋을때 우점적으로 나타나는 미생물이라고 알려져 있으므로 처리수의 수질과 관련하여 유추해 볼때 상당한 타당성이 인정되었다.
