This invention discloses a rapid annealing apparatus and method for micro / nano-scale metal samples. A metal indenter and a micro / nano-scale metal sample are prepared separately. The micro / nano-scale metal sample is placed at the fixed end of an electromechanical sample rod, while the metal indenter is mounted on the movable end, with the two ends facing each other without contact. Under a transmission electron microscope, the metal indenter is aligned and brought closer to the sample by a piezoelectric ceramic drive. After the indenter and the micro / nano-scale metal sample reach critical contact, several pulsed currents are applied. Then, by controlling the displacement of the piezoelectric ceramic, the cyclic movement of the metal indenter is achieved, thereby applying a constant strain amplitude of pressure-pressure cyclic loading to the micro / nano-scale metal sample. Then, pulsed currents are applied again, and this process is repeated multiple times, thus achieving rapid annealing of the micro / nano-scale metal sample using electromechanical coupling. The micro / nano-scale metal sample annealing method of this invention allows for in-situ observation at the micro / nano scale, with controllable parameters, high success rate, high efficiency, and good stability.

This invention discloses a process for the synergistic treatment of multiple wastes using an anaerobic system. Utilizing one or more anaerobic organic wastewater treatment systems, one or more types of externally generated waste are selectively introduced into the system. Organic pollutants in the water act as electron acceptors, and through microbial metabolism, the waste is rendered harmless and recycled, while also enhancing the system's processing capacity, generating energy, or recovering resources. The method includes five treatment modes: treating organic waste to increase biogas production, treating ferrous sulfide waste to recover ferrous sulfide, treating hexavalent chromium-containing waste liquid to recover chromium, treating nitrogen-containing waste to reduce it to nitrogen gas, and controlling sulfur-containing odors and performing in-situ desulfurization. Waste activated carbon is added in slurry form after grinding and fluidization, and the desulfurization mode uses a sulfate-free ferrous salt solution. This invention expands the anaerobic system into a synergistic treatment center for multiple industrial wastes, achieving waste-to-waste treatment, increased energy production, and resource recovery. The process is flexible and highly adaptable.
