The invention discloses a method of co-processing zinc-rich gypsum slag and jarosite slag, which comprises the following steps of: uniformly mixing the zinc-rich gypsum slag, the jarosite slag and a reducing agent, pressing into balls, putting the obtained balls into a reduction furnace, drying, pre-dehydrating, and then carrying out reduction vulcanization roasting to obtain a roasted material containing zinc sulfide, calcium sulfide and metal iron, mixing the roasted material with water, and acidifying in a three-phase fluidized bed by adopting hydrogen sulfide to obtain a calcium hydrosulfide solution and acidified slag, performing carbonation treatment on the calcium hydrosulfide solution to obtain a calcium carbonate product and hydrogen sulfide gas, and performing magnetic separationon the acidified slag to obtain iron ore concentrate, wherein magnetic separation tailings are zinc sulfide enriched slag. According to the method, calcium, zinc, sulfur and iron resources in the gypsum slag can be comprehensively recycled, secondary waste slag, waste gas and wastewater are not generated in the whole process, the method is environmentally friendly, full-quantitative utilization of the jarosite slag and the gypsum slag can be achieved, and the method has good application and popularization prospects.

The invention provides a new energy data sharing method. The method comprises the steps of classifying, packaging and screening real-time new energy data scheduled in each region of a power grid and extracted in advance, and then importing the new energy data into a source data end of an operation data platform in each region; periodically encoding the imported new energy data by using the sourcedata end of the operation data platform of each region, and importing the encoded new energy data into a regulation and control cloud platform in a unified manner; and feeding back the interacted real-time data to each region for scheduling through the message bus by passing through the source data end of the operation data platform of each region so as to realize data interaction and sharing, wherein the regulation and control cloud platform comprises a regulation and control cloud platform database and hierarchical deployment regional cooperation nodes. Through data processing and information sharing of massive new energy data in a power system, the accurate perception of regulation and control personnel on new energy information of the whole network is improved, and the data potential is effectively mined; a perfect power grid regulation and control strategy is formulated according to the real-time shared information, and the working efficiency of power grid dispatching personnel isimproved.
