Fremgangsmåde til behandling af en spildevandsstrøm ved anvendelse af en bioreaktor og et membranfilter |
摘要 |
Method for treating a fluid aqueous waste stream comprising a biodegradable organic substance, comprising
- feeding said stream into a bioreactor containing a fluid which contains biomass;
- reacting the biodegradable organic substance with the biomass in the bioreactor under essentially anaerobic conditions;
- taking a first flow from the bioreactor and using the first flow for a feed to a membrane filtration unit, in which said feed is subjected to filtration, thereby forming a permeate stream and a retentate stream;
- returning the retentate stream to the bioreactor;
- taking a second flow from the bioreactor as feed to a sludge treatment unit, in which sludge treatment unit the second flow is separated into a third flow, having an increased organic substance content compared to the second flow, and a fourth flow, having a decreased organic substance content compared to the second flow. |
