In general, majority of MOFs are powder, which limit their applications. In this study, the highly stable Zr-based MOF-808 and its thiol-modified MOF-808-SH were selected as precursors, and then they were wrapped by sodium alginate hydrogel via a dripping strategy. Based on these, MOF/hydrogel composite beads(Alg-MOF-808, AlgMOF-808-SH) with 3D network structure were prepared successfully. Due to its excellent adsorption properties and easy recovery, they were employed as effective environmental functional materials for the adsorption of Hg(Ⅱ). The adsorption capacities of Hg(Ⅱ) were 170.52 mg·g-1and 221.73 mg·g-1respectively and they can achieve adsorption equilibrium in a short time. The adsorption stability of Alg-MOF-808-SH was studied at different p H as well. In addition, the removal efficiency of composite beads for Hg(Ⅱ) was almost unaffected by other coexisting ions, displaying good adsorption selectivity. Furthermore, the removal efficiency only decreased by 10.4% after 5 cycles, indicating that the as-prepared materials have high recycling efficiency. The results demonstrated that the MOF/hydrogel composite beads have a certain application potential for mercury removal in actual wastewater.

Time-triggered Ethernet(TTEthernet or TTE for short) is a deterministic and congestion-free network based on the Ethernet standard. It supports mixcritical real-time applications by providing different message classes. The time-triggered(TT) messages have strict end-to-end delay and accurate jitter requirement, and the rate-constrained(RC) messages have less determinism than TT messages but with bounded end-to-end delay requirement. Traditionally, the scheduling of TT messages makes it free of conflicts for the transmission on physical links, but ignoring RC messages scheduling, so it cannot guarantee the transmission of RC messages with a bounded delay. Therefore, the design of TT schedule becomes the key to TTE network applications within avionics environment. In this paper, we propose an algorithm called RLTS based on reinforcement learning and tree search, to optimize the end-to-end delays of both TT and RC messages. Besides, its computation speed is dozens of times faster than satisfied modularity theory(SMT) with asynchronous method for the calculation of the optimal scheduling table. In the case of a large network with more than1000 TT and 1000 RC messages, the RLTS method can find a scheduling timetable in 10 seconds, and reduce the worst-case delay of RC messages averagely by 20% compared to the genetic algorithm. Meanwhile, our algorithm has a good generalization performance, in another word, it can quickly adjust itself to satisfy the scheduling with the similar performance as before. By using our method, the scheduling pattern of TTEthernet is further *** to the experimental results, the uniformly distributed slots scheduling pattern, namely the porosity scheduling model which is usually recommended for TTE application, is not always suitable for general situations.

A炼油厂酸性水汽提装置存在主汽提塔塔盘堵塞及净化水中硫化物过高问题。造成主汽提塔塔盘堵塞的主要原因是:酸性水中含有污油、氰化物、MDEA、环烷酸盐等杂质,这些杂质在操作过程中或聚合,或降解,或与其他物质反应生成一些沉积于塔盘的固体颗粒物或胶状物;通过增加酸性水在原料水罐及上游装置相关设备内的停留时间、适当降低主汽提塔进料板与塔顶之间的温差或适当提高塔顶温度、增加汽提蒸汽量、降低汽提蒸汽温度、降低酸性水原料中的氧含量、将中部塔盘更换为抗堵塔盘等措施,可有效解决主汽提塔塔盘堵塞问题。造成净化水中硫化物过高的主要原因是:酸性水原料携带的稳定硫化物及操作过程中反应生成的稳定硫化物等不能通过汽提的方式除去;通过降低含有MDEA或热稳定盐的酸性水量、降低酸性水原料中的氧含量等措施,可有效降低净化水中硫化物含量。
