The present disclosure provides a light particle system or a mixed particle system for wastewater treatment comprising a contactor. The contactor includes a gas-liquid-solid three-phase region, and the gas-liquid-solid three-phase region includes gas phase, liquid phase, and solid phase. The liquid phase is a continuous phase and the solid phase is light particles or mixed particles. The mixed particles include light particles and heavy particles. The density of the light particles is lower than the density of the liquid phase and the density of the heavy particles is higher than the density of the liquid phase. The light particles or mixed particles are able to carry some microorganisms on their surfaces at least. The light/mixed particle-suspension system in the present invention applied in wastewater treatment can increase the concentration of microorganisms significantly, improve the ability to bear impact load, produce less sludge, and without sludge expansion. The ability to suspend particles under the combined effect of gas and liquid is able to reduce energy consumption to a larger extent. Therefore, this system features both high efficiency and low energy consumption.

The present invention provides a method and tool for restoring a crashed operation system of a computer, for example, by operating under DOS environment to restore a crashed Windows system without requiring a long time setup and reinstallation. According to the present invention, a matching table for short file names to long file names is established for all files (containing directory names) on a disk. Then the long file names can be retrieved from short file names in accordance with the matching table. Since the long file names are stored in Unicode, they are workable for operation systems of any language.
