    摘要: A wastewater treatment process elicits microorganisms to convert a waste stream/organic resource to intracellular biopolymer polyhydroxyalkanoate (PHA). The process includes (i) waste stream/organic resource composition feed criteria, (ii) configuration coupled with operational parameters, and (iii) PHA-laden biomass separation and stabilization. A waste stream/organic resource capable of producing enhanced levels of PHA may be selected based on a combination of criteria, which may include short chain fatty acid concentration, protein concentration, polysaccharides concentration, and total suspended solids concentration. The waste stream is introduced into an aeration basin upon a specific configuration and operated under various parameter combinations for selecting/enriching microorganisms capable of producing PHA. The PHA-laden biomass is separated and stabilized for downstream PHA related product beneficial uses. The present process achieves concurrent wastewater treatment and PHA production, where PHA level (of more than 10% on a cell-weight basis) otherwise could not be obtained.
