[0036] Example 1
[0037]In the embodiment of the present invention, a printing and dyeing sewage treatment agent is made from the following raw materials according to parts by mass: 70 parts of diatomaceous earth, 40 parts of attapulgite, 90 parts of modified starch, 15 parts of acrylamide, and 2 parts of ferrous sulfate , 20 parts of magnesium sulfate, 10 parts of sepiolite powder, 10 parts of cross-linked rectorite, 0.5 parts of polyacrylamide, 20 parts of cationic monomers, 0.17 parts of initiator, and 0.09 parts of cross-linking agent. The cationic monomer was 3-chloro-2-hydroxypropyltrimethylammonium chloride. The initiator is manganese pyrophosphate. The crosslinking agent is hexametaphosphate.
[0038] The preparation method of modified starch, comprises the following steps:
[0039] (1) Dissolve starch in a mixed aqueous solution of 6% sodium hydroxide and 3% ammonia solution, stir for 2-3 hours, freeze-thaw, then dialyze, freeze-dry, and use for later use;
