The invention provides a yellowing process of viscose production. The process comprises the following steps: (A) after yellowing reaction is ended, adding primary dissolution alkali and secondary dissolution alkali into a yellowing machine successively, and adding primary dissolution water while adding secondary dissolution alkali; (B) opening a discharging valve to enable cellulose sulfonate in the yellowing machine to flow to a grinding machine from a discharging pipeline, and adding secondary dissolution water into the discharging pipeline while opening the discharging valve; (C) when the discharging rate is more than 90%, adding flushing alkali into the yellowing machine, and fully discharging, namely ending a yellowing cycle. According to the process, the dissolution water is added while the dissolution alkali is added, so that the time for separately adding the dissolution water is saved and the purposes of shortening the production cycle of the yellowing machine, increasing the production capacity of the yellowing machine, improving the operating stability of equipment and reducing the current consumption of the equipment and the energy consumption are achieved.

The invention provides a yellowing system for viscose fiber production. The yellowing system comprises a yellowing machine, a discharging valve, a discharging pipeline and a pulverizer, wherein the yellowing machine, the discharging pipeline and the pulverizer are sequentially connected to one another, and the discharging valve is arranged between the yellowing machine and the discharging pipeline. The yellowing system is characterized in that the discharging pipeline is connected to a liquid inlet pipe; after yellowing reaction ends, dissolved alkali and primary dissolved water are added to the yellowing machine, after addition ends, the discharging valve is opened, meanwhile, secondary dissolved water is added to the discharging pipeline through the liquid inlet pipe, when discharging reaches above 90%, flushing alkali is added to the yellowing machine, and after flushing ends, the discharging valve is closed, and the pulverizer is stopped. The yellowing system has the advantages that the production cycle of the yellowing machine is effectively shortened, the capacity of the yellowing machine is improved, the operational stability of equipment is improved, the operating current of the equipment is reduced, and the energy consumption is reduced.

The invention discloses a N-Fe / FeC 3 The preparation method of @AC microbial fuel cell air cathode composite electrocatalytic material comprises the following steps: (1) adding activated carbon to deionized water, and ultrasonically dispersing to obtain a uniformly dispersed solution for use; (2) adding potassium ferrocyanide and Ultrasonic dispersion of polyvinylpyrrolidone in the solution obtained in step (1), and then vigorously stir; (3) slowly drop ferric chloride solution into the solution obtained in step (2), continue to stir, and then stand at room temperature for aging; (4) The solution obtained in step (3) is filtered and cleaned, and then dried in an oven to obtain the product; (5) the product obtained in step (4) is placed in a tube furnace and calcined in a nitrogen environment; after that, it is cooled to room temperature, that is Obtain the composite catalytic material. The microbial fuel cell composite catalytic material prepared by the invention has good catalytic activity and good stability, simple preparation process and low price, and is suitable for the industrialized application of the microbial fuel cell.
