Remaining sludge treatment agent preparation method

The invention provides a remaining sludge treatment agent preparation method, wherein the prepared treatment agent is used for pretreatment of remaining sludge, the remaining sludge is subjected to high-pressure breaking, the obtained supernatant of the remaining sludge is taken and added with a complex bacterial agent, enzyme production by culture is performed, the complex bacterial agent comprises bacillus licheniformis and bacillus cereus, and one or two of Ca and Mg is/are added simultaneously when the complex bacterial agent is added. According to the method of the invention, theremaining sludge is subjected to high-pressure breaking, the supernatant is taken and utilized, and the results show that the maximum protease activity and the maximum amylase activity in the early stage can reach 252.31+/-1.40 U/mL and 266.86+/-8.40 U/mL respectively; and one or two of the metal ions including Ca and Mg are newly introduced, so that the humic acid inhibitors in the sludgecan be shielded, and the
