The invention discloses a sludge conditioner, which comprises the following components in parts by weight: 35-60 parts of filler, 30-55 parts of flocculant, and 5-10 parts of cationic modified starch. The sludge conditioner of the present invention can be added into the concentrated sludge to change the properties of the two-phase interface, and at the same time, its cationic head group can sterilize the bacteria and microorganisms in the sludge, and weaken the interaction between the bacteria and the extracellular polymer (EPS). The adhesion force makes the EPS on the sludge surface fall off and dissolve in the solution, which changes the form of the sludge flocs, and finally leads to excellent sludge dewatering effect and low moisture content of the treated sludge; moreover, its stability is good, The dosage is small, and the amount of sludge generated is small. |
