The invention discloses an integral process for ecologically desilting and curing
sludge. The process comprises the following treatment steps of: I, absorbing riverbed
sludge in an undistributed way; II, pretreating landed
slurry based on high-
frequency oscillation; III, decreasing and concentrating
slurry-containing
sewage while adding a flocculating agent A; IV, performing
solid-liquid separation on the concentrated
slurry, conveying the concentrated slurry in a decreasing and concentrating pond to a horizontal
centrifuge, adding a flocculating agent B and centrifuging to obtain dehydrated slurry cakes; V, inputting the dehydrated slurry cakes into curing equipment, adding a curing agent to obtain cured
sludge, introducing
sewage drained from the
centrifuge into an adjusting pond, adding a flocculating agent C, homogenizing, blending, elevating to a purifying
tower through an elevating pump, and adding a flocculating agent D; and VI, making a purified liquid part drained from the purifying
tower reflow for utilizing, and making precipitated concentrated slurry reflow to the decreasing and concentrating pond for retreating. The integral process has the advantages of high desilting efficiency, low cost, no secondary
pollution, small floor area, and detachability and
assembly for rapid transition.
