Method for testing mechanical strength of aerobic granular sludge

Номер: CN116067846A
Принадлежит:

The invention discloses a method for testing the mechanical strength of aerobic granular sludge, which comprises the following steps of: shearing an aerobic granular sludge sample at different rotating speeds by adopting a laser particle size analyzer, and removing points with larger deviation through a change diagram of Dv10/50/90 along with action time; drawing a particle size distribution change diagram under the action time at equal intervals; software is used for analyzing and extracting change rate or variable quantity S information of peak area and the like, a scatter diagram with action time as a horizontal coordinate or S as a vertical coordinate is drawn, a curve is fitted, and the mechanical strength is represented through curve quantification. Wherein the smaller the change rate (or variable quantity) of the peak area is, the better the mechanical strength of the aerobic granular sludge is. According to the method, simple and accurate quantitative characterization and standardized ...
