Abstract:

The composition of microorganism extracellular polymeric substances(EPS) together with their floccula-bility,adsorbability and biodegradability are introduced. Then,the extraction and preparation process of EPS are described briefly. Combined with EPS potential applications to feed-water treatment,wastewater treatment and sludge treatment,the advantages and limitation of EPS application are analyzed. The prospect and developing directions of EPS as flocculent and adsorbent applied to water treatment fields are predicted.

Key words: microorganism, extracellular polymeric substances, flocculation, adsorption, water treatment
