樓主要測啥的表面電荷?給個測活性污泥表面電荷密度的吧。 The measurement of surface charge of the sludge flocs was performed by colloidal titration [21]. A known volume of sludge sample diluted in distilled water was reacted with an excess amount of polybrene (Polyscience Inc.) (0.001N), followed by back-titration with polyvinyl sulphate (Aldrich–Fluka) (0.001N) to a colorimetric end-point indicated by Toluidin Blue. The surface charge was expressed as milliequivalents per gram of mixed liquor suspended solids of positive or negative colloidal charge, i.e. meq./g MLSS. The standard deviations for triplicate samples were 3–10%. 引自:Bo Jin, Britt-Marie Wilén, Paul Lant.A comprehensive insight into floc characteristics and their impact on compressibility and settleability of activated sludge.J. Chemical Engineering Journal 95 (2003) 221-234 |
