The invention discloses a method for recovering lead from waste lead plaster by a solid-phase electrolysis method, belonging to the technical field of lead resource recovery. Firstly, the waste lead paste is made into a pasty waste lead paste electrolytic material, and coated on the cathode plate; the electrolyte solution is added to the electrolytic cell; the cathode plate coated with the electrolytic material is inserted into the electrolyte solution, and the anode is inserted into the electrolyte solution middle; the anode is an electrode with oxygen-evolving electrocatalysis; the cathode plate and the anode are respectively connected to the negative pole and the positive pole of the DC power supply, so that electrolysis takes place in the electrolytic cell; the water on the anode loses electrons to precipitate oxygen, and the electrolytic material on the cathode plate is obtained The electrons are reduced in situ to generate simple lead, which is attached to the cathode plate, that is, lead is recovered from waste lead paste. In the present invention, the waste lead paste is directly electrolyzed after simple pulping, and the lead sulfate, lead dioxide and lead monoxide in the waste lead paste are obtained by electrons to generate lead element in situ, which saves a large number of pretreatment procedures and reduces reagents. The consumption makes the process simple and reduces the cost.

The invention relates to a calcium-based bentonite preparation process. The calcium-based bentonite preparation process adopts the following calcium-based bentonite preparation device. The calcium-based bentonite preparation device includes a preparation cylinder, a bottom plate, a plugging block, a sealing frame, a stirring motor and a stirring mechanism; The preparation process of calcium-based bentonite by the above-mentioned calcium-based bentonite preparation device includes the following steps: S1, calcium-based bentonite pulverization; S2, preparation cylinder cleaning; S3, calcium-based bentonite stirring; S4, slurry collection; S5, calcium-based bentonite subsequent treatment . The present invention can solve the problem existing in the purification operation for the preparation of calcium-based bentonite: when the calcium-based bentonite is discharged from the upper suspension, it usually adopts the method of dumping, which will pour out the calcium-based bentonite slurry together, and after pouring The coarse slag at the bottom of the slurry will move back to the calcium-based bentonite slurry.

The invention discloses a soft storage allocation method for the hybrid automatic repeat request process of a long term evolution system. The method comprises the following steps of: a downlink shared channel of the long term evolution system adopts a multi-process hybrid automatic repeat request technology and maximally performs transmission for 4 times, a transmitter transmits a redundancy version of a transmission block every time and can transmit two transmission blocks at a time in a space division multiplexing mode, wherein the transmission block TB can be divided into N coded blocks CB1, CB2, ..., and CBN, [] represents rounding-up and A is the number of information bits of the transmission block; and only one process of a receiver in any downlink sub-frame receives a currently transmitted transmission block. By the method, soft storage resources required by the multi-process hybrid automatic repeat request process are effectively reduced. The method is applied to various usage scenarios of the long term evolution system, and is highly robust.

The invention discloses a method for recovering junk data in a cloud storage log file system, used for solving the technical problem that the storage space of the existing junk data recovery method is poor in utilization rate. The technical scheme provided by the invention is as follows: the junk data is judged at first; a new log is established when the file system is updated; an index node in the log comprises a three-grade index structure; each file corresponds to one index node; an index address of a data block is stored in the three-grade index structure; the junk data is searched by taking the latest log as the base; the index addresses in the logs are sequentially compared from the earliest log; the data is stored in the log by the cloud storage log file system; the log is also stored in a segment storage file; and the junk data is recovered when the junk data amount of the segment storage file is more than a threshold value. According to the invention, the junk data is recovered manually or automatically; manual configuration of a segment file recovery threshold value is supported; the storage space occupied by the junk data can be recovered at any time; and thus, the utilization rate of the storage space is improved.
