Claim 0:
1. A curing agent for disposal of a municipal solid waste incineration (MSWI) fly ash, wherein the curing agent is prepared from the following raw materials in parts by mass:
loofah nanofiber crystal 1 to 10 parts;
rice husk ash (RHA) 30 to 100 parts;
sodium hydroxide 4 to 10 parts; and
water 60 to 100 parts,
the loofah nanofiber crystal is configured to be adsorbed on a surface of the MSWI fly ash and comprises a plurality of hydrophilic and lipophilic groups and active sites for adsorbing heavy metals in the MSWI fly ash;
the RHA has a specific surface area of 100 m2/g and is configured to provide a plurality of nanopores for adsorbing and curing the heavy metals; and
the sodium hydroxide is configured to excite and activate the RHA and to regulate a structure of the loofah nanofiber crystal.
