Abstract: A doped diamond particle-based three-dimensional electrode for water treatment and a preparation method therefor are provided. A boron-doped diamond plate electrode is used as an anode electrode, a titanium plate is used as a cathode electrode, and doped diamond particles are used as a filler that is assembled to form a filler module. The doped diamond particles include a core material, and a doped diamond film coating the core material. The doping element is one or more selected from boron, nitrogen, phosphorus, and lithium; and the core material is at least one selected from diamond particles, boron-doped diamond particles, metal particles, and ceramic particles. Doped diamond particles having a loose porous structure are used as a filler, to greatly increase the electrochemical active area and the adsorbable area.

Abstract: Heterogeneous garbage types are collected by scanning all of the service items to identify all of the service types that are included within the service items, identifying garbage collection components that correspond with the service types, and then collecting garbage for the corresponding target service types by using the corresponding garbage collection components.

Abstract: The disclosed embodiments provide a task scheduling method and apparatus. Network resources needed for a task to perform cross-cluster reading and writing are analyzed to obtain usage information of the occupied network resources for reading and writing; and the task is scheduled according to the usage information of the network resources needed for reading and writing. Because the usage information of the network resources occupied for reading and writing respectively represent network resources that can be saved by the cluster where access data is located when the task is scheduled for reading and writing, it can be determined that the cluster to which the task is scheduled can enable the task to occupy less network resources, thereby solving the problem of high bandwidth usage across clusters in current systems.
