description The invention discloses a domestic sewage treatment agent and a preparation method thereof, and belongs to the field of sewage treatment. The method includes the following steps: (1) drying and dehydrating activated sludge; (2) mixing the activated sludge after drying and dehydrating, boronatrocalcite, calcium carbonate and sodium-based bentonite, placing in a low temperature pulverizer, pulverizing, and sieving with a 150 mesh sieve after pulverizing, to obtain a mixed powder; (3) immersing chitin modified plant fibers and cellulase into a bamboo vinegar liquid, soaking for 1-2 h, and freeze-drying to constant weight for standby application; (4) adding the mixed powder, polysilicon aluminum sulfate, calcium chloride, calcium lignosulfonate, aluminum chloride, ferric trichloride, sodium acetate, acetylated lanonol, glyceryl monostearate and a potato powder into water, and mixing uniformly; and (5) adding sodium alginate, drying under a condition of the temperature of 130-150 DEG C, pulverizing again, and cool
