The present application discloses a
sludge treatment slow-release material and a treatment method, and belongs to the technical field of
sludge treatment. A water-soluble
coating material forms a slow-release film on the surface of an iron-carbon micro-
electrolysis filler, and the slow-release film slowly dissolves in the
sludge to slowly release the iron-carbon micro-
electrolysis filler. The iron-carbon micro-
electrolysis filler undergoes a
galvanic cell reaction in the sludge, and the generated
divalent iron ions can catalytically activate
persulfate to produce
persulfate radicals and trivalent iron ions. The
persulfate radicals can oxidize
nitrogen-containing
organic matter, and the trivalent iron ions react with phosphates to generate
iron phosphate precipitates; the dissolved water-soluble
coating material complexes with
heavy metals, thereby achieving the purpose of removing
nitrogen-containing
organic matter,
phosphorus-containing
organic matter and
heavy metals in the sludge. The slow-release material can slowly release the iron-carbon micro-electrolysis filler, thereby continuously producing stable
divalent iron ions, prolonging the
active time of persulfate, and then prolonging the
treatment time of the slow-release material on the sludge, achieving the purpose of long-term repair.
