The invention relates to a method for rapidly representing
sludge dewatering performance. The method comprises the following steps of: collecting 100ml of raw
sludge or concentrated
sludge; filtering with a filter membrane of 0.45mu m to obtain 10mL of sludge supernatant; measuring soluble organic carbon (DOC) of the supernatant; diluting the supernatant with
distilled water until the DOC is less than 10mg / L; collecting a three-dimensional
fluorescence spectrum (EEM) of the diluted supernatant; substituting the collected EEM spectrum into a
database to analyze a parallel factor (PARAFAC) by using a DOMF1uor tool kit of Mat1ab 7.0
data processing software to determine a
score of a component with excitation and transmission
wavelength of (220,280) / 350nm; and multiplying the
score by a diluting multiple of a sample and substituting the product into a
sludge dewatering performance judgment relational formula to represent the
sludge dewatering performance. By the method, the
sludge dewatering performance can be rapidly detected without chemical
reagent, and the detection can be completed only through filtering, diluting and three-dimensional
fluorescence spectrum; and the method can be applied to monitoring the
dewatering performance of various types of sludge of sanitary
sewage treatment factories, industrial
sewage biological treatment factories and the like.
