A method of switching between mobile networks comprises the steps of: receiving, by a server, a mobile network switching request from the communication terminal input by a user; outputting, by the server, a list of mobile networks where the communication terminal is currently located to the user in response to receiving the mobile network switching request from the communication terminal; acquiring, by the communication terminal, a switched-to mobile network selected by the user from the list of mobile networks; allocating, by the server, a SIM card corresponding to the switched-to mobile network to the communication terminal; and switching, by the communication terminal, a switched-from mobile network to the switched-to mobile network by means of the SIM card. The problems in the prior art of being unable to freely change a virtual subscriber identity model card and switch a corresponding mobile network are effectively solved, thereby improving the user experience.

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.
