    摘要: A rotary-drum mechanical surface decontamination method for radioactively contaminated metal first places a feed chute fully loaded with radioactively contaminated metal on a hydraulic lift platform of a dual-chain roller conveyor and then moves the feed chute to a hydraulic cover-opening machine for positioning, and then uses a hydraulic cover-opening machine to open the cover of the feed chute, while non-covered feed chute will advance further to the post on a feed hopper of a drum spray washer, and then drop the workpieces into a conical drum for rotary multi-angular spray washing. The decontaminated metal waste is transferred by a vibrating discharger onto a conveyor and then into a discharge tank, and to the hydraulic cover-opening machine by a dual-chain roller conveyor, and to the hydraulic lift platform to complete the decontamination process.

    摘要: A method for concentrating sugars and decreasing fermentation inhibitor concentrations simultaneously before fermentation is disclosed. The method includes the steps of adjusting the pH value of a hydrozylate containing sugars and fermentation inhibitors; separating solid and liquid in the hydrozylate, for removing large particles in the solution; and applying a semi-permeable membrane, for concentrating the sugars and decreasing the total concentration of the fermentation inhibitors in the hydrozylate, so as to obtain a concentrated solution. By the aforesaid method, the sugar concentrations in the hyrozylate are increased, thereby increasing the concentration of ethanol in the subsequent fermentation. Therefore, the cost of purifying ethanol and the volume of the fermentation tank are both reduced. Moreover, the total concentration of the fermentation inhibitors, such as acetic acid, furfural and hydroxymethyl furfural (HMF), is decreased, favoring onset of fermentation.
