    • Advanced treatment method and system of ethanolamine-containing wastewater are disclosed, which perform physicochemical and biological treatment processes. The method regenerates cation exchange resin that captures ethanolamine discharged from a nuclear power plant or a thermal power station, concentrates the ethanolamine-containing wastewater to reduce the volume of the wastewater, and then treats the highly concentrated ethanolamine-containing wastewater through biological decomposition and denitrification processes. The system for treating ethanolamine-containing wastewater performs the physicochemical process (ion-exchange and resin regenerations) where the waster is concentrated, and then applies the biological process to the small amount of wastewater highly concentrated. The physicochemical process is composed of exchanging ions and eluting/concentrating ethanolamine using sodium hydroxide. The wastewater of a few to tens of thousands ppm is transferred and undergoes a biological process where the ethanolamine is decomposed, converted into CO2 and N2 through the anoxic tank and two aerobic tanks, and then discharged in gas. Therefore, the wastewater is discharged, satisfying the biochemical oxygen demand value and the nitrogen content required by the environmental discharge standard.
    • 公开了含乙醇胺废水的先进处理方法和体系,进行物理化学和生物处理工艺。 该方法重新生成捕获从核电厂或火电厂排出的乙醇胺的阳离子交换树脂,浓缩含乙醇胺废水减少废水体积,然后通过生物分解和脱氮处理高浓度含乙醇胺废水 过程。 处理含有乙醇胺废水的系统进行废水浓缩后的物理化学过程(离子交换和树脂再生),然后将生物过程应用于少量高浓度废水。 物理化学过程由交换离子和使用氢氧化钠洗脱/浓缩乙醇胺组成。 转移几ppm到几万ppm的废水,经过乙醇胺分解的生物过程,通过缺氧罐和两个需氧罐转化成二氧化碳和氮气,然后排放气体。 因此,废水排放,满足生化需氧量和环境排放标准要求的氮含量。

    • A monitor apparatus having a monitor main body, and a base member to support the monitor main body includes a stand member placed between the monitor main body and the base member, a base hinge to connect the stand member to the base member, so that the stand member is rotated relative to the base member and folded, and a rotation control unit to prevent and allow a rotation of the stand member relative to the base member. Thus, a package volume of the monitor apparatus is reduced, so that a cost to keep and move the monitor apparatus is saved, and an accident occurred when the stand member is suddenly rotated is prevented.
    • 具有监视器主体的监视器装置和用于支撑监视器主体的基座部件包括:放置在监视器主体和基座部件之间的支架部件,将支架部件与基座部件连接的基座铰链, 支架构件相对于基座构件旋转并折叠;以及旋转控制单元,用于防止和允许支架构件相对于基座构件的旋转。 因此,监视器装置的封装体积减少,从而节省了保持和移动监视器装置的成本,并且防止了立体构件突然旋转时发生事故。
