Abstract: Disclosed is a device for efficiently recycling nickel from wastewater and a method. The device includes a housing, and an extraction unit and an electro-deposition unit which are respectively arranged inside the housing. The device is reasonable in overall structural design. An oscillating and floating component and a rotating component in an extraction cavity are used to fully and uniformly mix a solution to maximize the extraction strength. A mixing component in an electro-deposition cavity is used to accelerate ion dispersion, to better recycle nickel. The device is easy to operate, low in cost and suitable for mass promotion.

Abstract: A method and an apparatus for monitoring single board running state are disclosed in the present invention. The above method comprises: establishing an Module Management Controller (MMC) communication channel between a slave board and a master control board when the slave board is powered up; and the slave board reporting running state information of the slave board to the master control board by the MMC communication channel according to one or more preset monitor information points. In the present invention, by the MMC function channel under the uTCA architecture, the slave board reports the master control board the running state of the working process from the moment of being powered-up to the time when the system runs stably, which solves the problem in the conventional art that the monitoring on the single aboard is incomprehensive and can record the running state of the slave board completely.
