The invention relates to an integrated mine water fluorine turbidity removal agent and a preparation method thereof. The medicament is prepared by grinding, mixing and granulating a flocculating agent, activated aluminum oxide and a binder, the binder accounts for 1-5% of the total weight of the medicament, and the flocculating agent is PAC. The mine water fluorine turbidity integrated removal agent integrates the functions of the flocculant, the fluorine removal agent, the coagulant aid and the dense medium, can realize the integrated removal of the mine water fluorine turbidity, and correspondingly simplifies the water treatment process flow.

This invention discloses a fabrication process for an all-solid-state battery without overhang, and the all-solid-state battery itself, belonging to the field of solid-state battery fabrication technology. The fabrication process provided by this invention includes: stacking a positive electrode roll, a solid electrolyte membrane roll, and a negative electrode roll with the positive and negative electrode material regions aligned to form a composite electrode roll; after preliminary bonding by roll forming, cutting into strip-shaped composite electrode sheets; vacuum sealing with an aluminum-plastic film after stacking; and then sending the stacked composite electrode sheets into an isostatic pressing device for densification treatment. The isostatically pressed composite electrode sheets are then cut into cells of the required size, and the cut surfaces of the cells are insulated before encapsulation to obtain an all-solid-state battery cell. This invention eliminates redundant structures, reduces battery short-circuit rate, increases energy density, simplifies process flow, and improves production efficiency. It is particularly suitable for large-scale production of high-energy-density, high-safety all-solid-state lithium-ion batteries.

This invention discloses a nucleogranulation device and its operating method, comprising an annular water distribution pipe installed below a tank, a sludge pipe installed on the tank at the bottom of the annular water distribution pipe, and a granulation reaction zone, a concentration zone, a separation zone, an inclined plate clarification zone, and an overflow trough arranged sequentially from bottom to top above the annular water distribution pipe. A packing device is installed in the separation zone; a drain outlet is provided on the overflow trough; a hollow barrel is located at the center of the granulation reaction zone, and an axial flow pump is installed inside the hollow barrel. The axial flow pump is used to pump part of the water in the concentration zone into the central hollow barrel and transport it to the center of the annular water distribution pipe, with the hollow barrel located directly above the annular water distribution pipe. A water flow disperser is installed at the bottom of the annular water distribution pipe. This invention can increase the operating load, increase the treatment depth, effectively improve the operating load and sludge concentration effect, and the discharged sludge can be directly dewatered, thus improving the effluent quality.
