Beschreibung
Zusammenfassung:	The invention relates to a composite sludge treatment process. The treatment process comprises the following steps: step a, removing impurities; step b, pre-treating the sludge to obtain first sludge and second sludge; step c, uniformly mixing the second sludge obtained in the step b with a solidifying agent by means of aeration treatment, and subsequently press-filtering and dehydrating the second sludge which is subjected to the aeration treatment to obtain a sludge cake; step d, adding a solidifying agent into the first sludge obtained in the step b and uniformly stirring; step e, sending the sludge cake obtained in the step c and the first sludge treated in the step d to a temporary storage yard, and standing for 1-2 days to finish the treatment. The composite sludge treatment process disclosed by the invention has the advantages of high efficiency, low cost and the like.
