The invention relates to the technical field of waste treatment and solidification, and discloses a fly ash slag and sludge synergistic stabilization treatment method which comprises the following steps: S1, raw material pretreatment: dehydrating fly ash by using a centrifugal dehydrator until the water content is lower than 10%, and treating the fly ash and slag by using a vibrating screen and a jaw crusher until the particle size is 0.5-2 mm; dehydrating the sludge until the water content is lower than 30% by using a belt filter press, and then drying the sludge in a hot air drying furnace until the water content is lower than 10%; s2, raw material mixing: mixing the pretreated fly ash, slag and sludge according to a set mass ratio; s3, adding a curing agent: adding the curing agent into the mixture, and uniformly stirring. By optimizing the proportion and selecting the proper curing agent, the problems of insufficient stability of a cured body and incomplete sealing of harmful substances are solved, and by treating the raw materials, adding the curing agent and optimizing the curing agent, the problems of poor sealing effect of heavy metals and high treatment cost are solved.

The invention provides a motor imagery electroencephalogram (MI-EEG) recognition method and a motor imagery electroencephalogram (MI-EEG) recognition system based on Kans-Transform, and aims to effectively improve classification accuracy and robustness. The method is realized through four key modules: a preprocessing module, a time domain and space domain feature extraction module, a Kans-Transform module and a classification module. The preprocessing module enhances data diversity and model generalization ability through filtering and data enhancement technologies. The time domain and spatial domain feature extraction module extracts time domain and spatial domain features of EEG by using a deep convolutional network, introduces an efficient channel attention (ECA) module after time domain convolution to perform channel attention weighting, and obtains more comprehensive feature representation through feature fusion. According to the Kis-Transform module, Kolmogorov-Arnold Networks are used for replacing the traditional MLPs, and the feature capturing capability is enhanced. And finally, performing classification through a classification module. The method still has excellent performance under the condition of limited labeled data, is suitable for brain-computer interfaces, and has important application value in the fields of rehabilitation medicine and human-computer interaction.

This invention provides a negative carbon thermal circulation upgrading furnace and its application, relating to the field of industrial solid waste treatment technology. The upgrading furnace includes at least three assemblable unit modules, each comprising a furnace body, multiple horizontally inserted U-shaped pipes, an air inlet main pipe, and an exhaust main pipe. The furnace body has a rectangular cross-section, with opposing through holes on the front and rear walls. The U-shaped pipes, including U-shaped air inlet pipes and U-shaped air outlet pipes, are inserted into these through holes. The U-shaped air inlet pipes are connected to the air inlet main pipe, and the U-shaped air outlet pipes are connected to the exhaust main pipe. Based on this main body, flue gas is introduced or discharged through the horizontally inserted U-shaped pipes, enabling flexible control of material drying, internal combustion, reheating, and cooling within the furnace. This invention also provides applications of the upgrading furnace. Through modular furnace design and a high-efficiency flue gas circulation system, this invention achieves low-energy, high-value treatment of various solid wastes, ultimately achieving a negative carbon target.
