The invention belongs to the field of
solid waste reclamation comprehensive utilization and particularly relates to a
soil conditioner prepared from
sludge and a preparation method thereof. The
soil conditioner is prepared from river and lake bottom mud, conditioner, medium sand, agricultural and
forestry residues, biological
manure and
plant ash, wherein the conditioner is 5% to 8% of the
mass of the river and lake bottom mud, the medium sand is 5% to 10% of the
mass of the river and lake bottom mud, the agricultural and
forestry residues are 5% to 10% of the
mass of the river and lake bottom mud, the biological
manure is 1% to 5% of the mass of the river and lake bottom mud, and the
plant ash is 1% to 3% of the mass of the river and lake bottom mud. The
soil conditioner prepared from
sludge disclosed by the invention achieves
resource utilization of
sludge, also fully utilizes sludge,
tailings or river and lake sand, tailing sand,
pipe network sand and agricultural and
forestry residues at the same, achieves the purpose of treating waste through waste, avoids
solid waste landfill, land occupancy and secondary
pollution, reduces
engineering cost of
land reclamation,
landscaping, forest land
plant and the like and is beneficial to
ecological environment; in addition, the river and lake sand, the tailing sand, the
pipe network sand and the agricultural and forestry residues are separated and sorted from
pipe network sludge.
