Abstract

See full text

Provided is a sludge drying composite conditioner. The sludge drying composite conditioner comprises a Fenton's reagent or/and Fenton-like reagent and a matrix construct, the weight ratio between the Fenton's reagent or/and the Fenton-like reagent and the matrix construct is 1:0.05 to 300, and the matrix construct is powder. Further provided is an application method of the sludge drying composite conditioner, which comprises the steps of: adding a Fenton's reagent or/and Fenton-like reagent in a sludge, performing stirring and mixing, and performing an oxidation reaction; and adding a matrix construct to the sludge added with the Fenton's reagent or/and Fenton-like reagent and performing stirring and mixing. For the sludge drying composite conditioner, through the coordinated effect of the Fenton's reagent or/and Fenton-like reagent and the powder matrix construct, the extracellular polymeric substances in the sludge are effectively damaged, the compressibility of organic matter is reduced, and the drying performance of sludge is improved. The application method thereof has a simple working process and easily controllable conditions and reduces the drying time for sludge, thereby achieving large-scale treatment of sludge.
