The invention discloses a mobile contaminated bottom mud bag pocket dewatering and volume reduction treatment method which is characterized by comprising the following steps of: transporting contaminated bottom mud in a river or water reservoir to closed pipeline mixers via an environment-friendly sand dredger or mud pump, throwing a stabilizing and curing agent into the first pipeline mixer, throwing a flocculating and conditioning agent into the second pipeline mixer, finally dewatering and reducing volume of bottom mud in geotex pipe pockets, and curing and stabilizing bottom mud contaminates. After the bottom mud in the geotex pipe pockets is solidified for 7-50 days, the moisture content of the bottom mud reaches less than 55%. The bottom mud in the bag pockets is transported off the site by using a mobile car body. Treatment or resource utilization reaches national relative standards. The technological innovation bridge spot of the method is 'environment-friendly sand dredging + agent + geotex bag pocket dewatering + natural drying of bottom mud + mobile car body'. Not only is the sludge treatment amount large during project implementation process, but also no site area is occupied, the technology is simple, and the operating cost is low. Good economic benefits are achieved.

The embodiment of the application discloses a data migration method, apparatus and device. The method comprises: according to the capacity of a storage device to be migrated in a storage system, a target migration device is added to the storage system to expand the capacity of the storage system; Performing write prohibition processing on the storage device to be migrated, and migrating data stored in the storage device to be migrated to the target migration device; a memory device to be migrate is removed from that memory system to perform a volume reduction processing on the memory system. With the embodiments of the present application, data migration and equipment replacement can be completed without interrupting service and affecting the quality of service of online services by volumeexpansion processing and volume reduction processing, thus not affecting the reading and writing of data in a storage system by a user, and the speed of data migration can be improved and the time consumed for data migration can be reduced.

The invention discloses a design method of flyback switching power supply transformer shield windings. The design method comprises the steps of (1) selecting a transformer, determining a connection type of the transformer shield windings, and measuring a structural dimension of the transformer, (2) setting turns of the shield windings as fixed values, and obtaining structural capacitance between the windings of the transformer under the different turns of the shield windings by utilizing simulation software, (3) calculating a common mode current equivalence coefficient in the transformer underthe different turns of the shield windings, and drawing a function relation characteristic curve of the common mode current equivalence coefficient and the turns of the shield windings, and (4) obtaining the turns of the shield windings when the common mode current equivalence coefficient is minimum according to the drawn characteristic curve, namely the optimal turns of the shield windings for inhibiting common mode current of the transformer. Compared with the existing common mode inhibition technique, the method has the advantages of simple device manufacturing, low realization cost, overall device weight and volume reduction, obvious inhibition effect and the like.

The invention discloses application of ferrous-iron feeding liquid in the aspect of promoting fermentation of bacterial groups for organic waste treatment. The bacterial groups for organic waste treatment include following bacterial genera of nemaline decomposing bacteria, streptomyces, pseudomonadaceae, aspergilli, penicillium, rhodopseudomonas, lactobacillus, bacillaceae and saccharomycetes. According to the ferrous-iron feeding liquid, decomposition fermentation of the bacterial groups for organic waste treatment can be accelerated, the fermentation period is greatly shortened, and the volume reduction rate is increased.
