    摘要： A process for producing PHA comprises obtaining biomass produced in the course of biologically treating a first wastewater source containing RBCOD. The biomass is to be exploited with a second wastewater source having a different RBCOD content from the first wastewater source in order to accumulate and thereby produce PHA. Before subjecting the biomass to a PHA accumulation process, the biomass PHA accumulation potential is enhanced via an acclimation process with the second wastewater source. During acclimation, the biomass is subjected to repeated feast-famine periods. During each feast period, the biomass is exposed to a fraction of the second wastewater source. The RBCOD uptake and/or biomass respiration rate is directly or indirectly measured during each feast period. The famine period is maintained for a period of time that is at least two times greater than the length of time of the proceeding feast period. After at least two feast-famine acclimation periods or after one or more measured parameters reveal an increased RBCOD relative uptake or respiration rate of the biomass during a subsequent feast period, the biomass is subjected to a PHA accumulation process using the second wastewater source.

    摘要： There is provided a method which eliminates a decrease in activity of an activated sludge treatment microorganism group, which greatly increases treatment ability of the microorganism group, to enhance treatment efficiency and to reduce the amount of excess sludge. The wastewater treatment method of the present invention includes, when raw water (1a) is subjected to an activated sludge treatment, performing a first sludge returning step (Va) (a step of returning sludge, which was previously aerated and stirred in a first excess sludge tank or sludge retention tank (12a) equipped with an aerator and a stirrer, to an treatment tank, a sequencing batch reactor or an anaerobic tank; and/or a step of returning sludge, which was previously aerated and stirred in a second excess sludge tank or thickened sludge retention tank (13a) equipped with an aerator and a stirrer, to a treatment tank, a sequencing batch reactor or an anaerobic tank), and maintaining the number of genus Bacillus bacteria in the treatment tank, the sequencing batch reactor or the anaerobic tank, to which the sludge has been returned, at 2.0×10 5 to 22.5×10 5 cfu/mL.
