Abstract

It has been found that yeasts and yeast-like microorganisms are stable constituents of activated sludge biocenosis treating municipal wastewaters with a mixture of different industrial wastewaters at B upsilon values in the range of 1.3-1.7 kg COD m-3day-1 and B chi = 0.22-0.42 kg COD kg-1day-1. The number of these microorganisms reached about 10(4) cells mg VSS-1 and as typical species Saccharomyces cerevisiae and Candida famata can be considered. Considerably less numerous (4-8 cells mg VSS-1) was the mycoflora of high loaded treatment systems of petrochemical wastewaters (B upsilon = 10.3-14.1 kg COD m-3day-1 and B chi = 1.06-1.92 kg COD kg-1day-1) and municipal wastewaters with a mixture of aromatic amines (B upsilon = 1200-2400 mg COD l-1 day-1 and B chi = 0.43-0.94 mg COD mg-1day-1). Typical species for these sludges were Geotrichum candidum, G.klebahnii, G.sericeum, Trichosporon cutaneum and Sporobolomyces lactosus.

摘要

已发现，在B₀值为1.3 - 1.7 kg COD m⁻³天⁻¹且B₁ = 0.22 - 0.42 kg COD kg⁻¹天⁻¹的条件下，用不同工业废水混合物处理城市污水时，酵母和类酵母微生物是活性污泥生物群落的稳定组成部分。这些微生物的数量达到约10⁴个细胞mg VSS⁻¹，典型物种可认为是酿酒酵母和法塔假丝酵母。在石化废水高负荷处理系统（B₀ = 10.3 - 14.1 kg COD m⁻³天⁻¹且B₁ = 1.06 - 1.92 kg COD kg⁻¹天⁻¹）以及含芳香胺混合物的城市污水（B₀ = 1200 - 2400 mg COD l⁻¹天⁻¹且B₁ = 0.43 - 0.94 mg COD mg⁻¹天⁻¹）中，真菌区系的数量要少得多（4 - 8个细胞mg VSS⁻¹）。这些污泥的典型物种是白色地霉、克氏地霉、丝光地霉、皮状丝孢酵母和乳糖掷孢酵母。
