摘要: A novel integrated isoelectric precipitation-nanofiltration (NF)-anaerobic fermentation process was proposed for fully recycling model dairy wastewater (MDW). Isoelectric precipitation at pH 4.80 and subsequent centrifugation could remove most proteins. Acetic butyric acids from anaerobic were available acidic precipitation, the performance comparable to that of hydrochloric acid. The pretreatment MDW by greatly retard NF membrane fouling, especially 7.09 owing electrostatic repulsion between solutes membrane. NF270 preferred concentration due its high antifouling performance, permeability acceptable permeate quality. Anaerobic fed with retentate without caseins produced higher proportion acetate, butyrate hydrogen, this effluent shorter-chain volatile fatty (VFAs) lower more suitable casein in wastewater.
