%X Reviewed in this article are the current studies abroad on enzyme in raw domestic sewage, sludge of septic tank, activated sludge, the bacteria and protozoa that play significant role during sewage treatment, In the process of hydrolysis and decomposition of organic matter, the bacteria practically play the exclusive role, while the protozoa act on flocculation and oxidation in sludge. This article also describes the relationship of enzymatic activities in activated sludge and quality of effluent. Toxic matter such as heavy metals will inhibit enzymatic activities because heavy ions associate with mercapto-(-SH).
