The granulation mechanism of micro-aerobic granules for PCP degradation
降解五氯酚（PCP）的微氧颗粒污泥的形成机理

Micro-aerobic granules were subjected to a PCP environment to study their granulation mechanisms. The characteristics and appearance of the sludge were studied and the microorganisms were analyzed by scanning electron microscopy during culturing. The results showed that in the initial period, the induced cores functioned as flocculants and filamentous bacteria were the dominant microorganisms; before the formation of mature granules, both the amount of bivalent metal cations and the PN/PS ratio increased, a...
