Abstract: The present disclosure provides a treatment method for oily sludge and a method for soil remediation. The treatment method for oily sludge includes: mixing the oily sludge with target biochar uniformly according to a first preset mass ratio, and conducting catalytic pyrolysis at a first preset temperature to achieve efficient removal of petroleum hydrocarbons, to obtain a pyrolysis residue used for soil remediation. In the present disclosure, the method realizes resource utilization and harmless utilization of the pyrolysis residue.

Abstract: The application discloses a method for preparing crude polysaccharides based on synergistic fermentation with corn stover and fungus, including the following steps: step (1): drying corn stover, pulverizing, placing in a hydrothermal reactor, adding deionized water, sealing the hydrothermal reactor, placing in a heating device, reacting, taking out reaction products, centrifuging and drying a solid; step (2): adding the products obtained in step (1) and dried bean curd residue to a container, adding distilled water, mixing uniformly, sterilizing to obtain a mixed material, inoculating a fungus inoculum under aseptic conditions, sealing the container and cultivating in the dark to obtain crude polysaccharides. The disclosure uses corn stover and bean curd residue as raw materials to achieve efficient utilization of discarded biomass, reduce environmental pollution, and improve utilization of corn stover.

Abstract: The present disclosure provides a copper-magnesium co-doped carbonized wood sponge material, a preparation therefor, and an application thereof, and a method for converting plastics into fuel based on a Fenton-like system. In the present disclosure, a copper-magnesium co-doped carbonized wood sponge catalyst is prepared by high-temperature pyrolysis after a wood raw material is coated with polydopamine (PDA) and a copper element and a magnesium element are loaded on a wood sponge substrate, realizing the loading of a nanoreactor on a wood sponge layered structure, and forming a unique spatial microenvironment and synergistic effect by combining a superior three-dimensional lamellar structure of the wood sponge substrate with the structural advantages of the nanoreactor to promote an electron transfer pathway on a surface.
