摘要： In an embodiment, the present invention provides a method for the biological cleaning of wastewater in an activated-sludge plant including at least one activated-sludge tank, the method including: contacting, in the plant, the wastewater with activated sludge in the activated-sludge tank so as to clean the wastewater; and after the cleaning of the wastewater, separating, in the plant, the suspended activated sludge from the cleaned wastewater by sedimentation in a secondary clarification tank downstream of the activated-sludge tank or in the activated-sludge tank. The activated sludge suspended in the wastewater is admixed with growth bodies in the activated-sludge tank in order to contact the growth bodies with the microorganisms present in the activated sludge and to bring about formation of a biofilm of microorganisms on the growth bodies.

摘要： An apparatus and method for selecting and retaining solids in an activated sludge process for the improving wastewater treatment using screens. The screens can be used to separate and retain solids based on size or compressibility. The screens are used to separate and select for slow growing organisms, faster settling organisms, or materials added to absorb, treat or remove constituents in the activated sludge process.

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.
