Abstract: A method for processing a workflow in combination with a task, a task processing method, and related devices are provided. During reporting the workflow, a task control is created in a preset area, in response to a task addition instruction. A target task to be added may be inserted into the task control for display. In this way, the workflow added with the target task can be reported to a target user.

Abstract: This invention belongs to the field of biochemical engineering and relates to a method of cyclic utilization of water during separation of succinic acid made by fermentation. This invention uses water from separation process for aerobic growth of E. coli AFP111 and production of succinic acid by anaerobic fermentation, obtaining final succinic acid concentration of 55 g/L and yield of 91.6%. Compared with results of fermentation using culture medium prepared from tap water, succinic acid concentration and productivity increased by 8.5% and 8.46%, respectively. An outstanding advantage of this invention is recovery and utilization of evaporated water during separation of succinic acid, realizing cyclic use of water during industrial production of succinic acid, which is an environment-friendly process.

Abstract: The present invention relates to a process for separating isomers by simulated moving bed (SMB) adsorption, comprising separating the raw materials comprising isomers by SMB adsorption, said SMB comprising many adsorption beds each of which is equipped with grids, each of the grids being equipped with the feedstock inlet and outlet pipeline of the bed, the feedstock charged into and discharged from SMB at least comprising feedstocks, desorbent, extract, and raffinate, the extract being enriched with the target product, characterized in that the extract is used as a flushing liquid and respectively charged to first or second bed at the upstream of the feedstock charging position and to one of second to fourth beds at the downstream of the extract withdrawing position. Such process is used for separation of C8 aromatic isomers by adsorption, and can improve the capacity of the device while effectively increasing the purity of the target product separated by adsorption.
