Embodiment 1
[0039] A rapid dehydration curing agent, including the following components:
[0040] 20 parts of iron sulfate,
[0041] 20 parts of ferrous sulfate,
[0042] 15 parts of silicon powder,
[0043] 10 parts of organic bentonite,
[0044] 30 parts of quicklime,
[0045] 0.01 parts of polyacrylamide (M=12 million).
[0046] The preparation method of described dehydration curing agent is as follows:
[0047] Accurately weigh the components in parts by weight, mix and grind until the particle size is less than 200 mesh, and obtain the product.
[0048] Sludge treatment method using fast dehydration curing agent:
[0049] The fast dehydration solidifying agent that is prepared is added to the sludge of a certain lake in Guangzhou (the initial moisture content is 88.3%, the lead leaching content is 9.26mg / kg, the mercury leaching content is 0.56mg / kg, and the arsenic leaching content is 7.56mg / kg. kg) in solidification test; the addition of the solidifying agent is 10% of the s...
