The invention discloses a method for constructing a stable solid interface on the surface of a positive electrode of a sulfur-based or selenium-based battery. The method comprises the steps of 1) assembling a sulfur-based or selenium-based positive electrode material into a battery; 2) discharging the battery with a first-cycle discharging current when the battery is discharged for the first cycle; 3) when the battery is charged for the first circle, charging the battery with a first-circle charging current greater than the first-circle discharging current; and (4) using the battery at the circulating working current greater than the first-circle discharging current all the time in the using process of the battery. According to the method for constructing the stable solid interface on thesurface of the positive electrode of the sulfur-based and selenium-based battery, the circulating stability of an electrode material can be improved, and the capacity of rapidly charging and discharging the interior of the battery is improved at the same time.

The invention relates to the technical field of biological remediation of organic polluted soil, in particular to a strengthening remediation method and device for a bioreactor. The three-in-one windpower integration device comprises a leachate reciprocating distribution system, a power supply system and an electrolyte nutrient supply system pipeline; and the leachate reciprocating distribution system is arranged at the bottom of the device, the power supply system is composed of at least one electrode group of a sandwich-liked structure, and the electrolyte nutrient supply system is composedof the electrolyte nutrient supply system pipeline and an intermediate layer electrolyte nutrient supply system pipeline. According to the method and the device, the cathode design of a wind power integration mode effectively improves the anoxic environment at the bottom of a reactor body, so that secondary pollution is avoided and organic pollutants are thoroughly removed through the leachate circulation design, the remediation efficiency of the bioreactor technology on the organic polluted soil is effectively improved, and the method is an effective realization method for strengthening application of the bioreactor repair technology.

The invention discloses a mineral fiber treatment system and a treatment method thereof, comprising a slag removal device, a chopping device and a drying device which are sequentially arranged and used for respectively carrying out slag removal, chopping, drying and screening of mineral fibers containing ball slag and grading device; the slag removal device can not only effectively remove the ball slag mixed in the mineral fiber, but also reduce the loss of the mineral fiber in the slag removal process and improve the productivity of the mineral fiber; and then pass through the chopping device, drying device and The grading device chops the mineral fibers, dries them, and removes too short mineral fibers and other fine impurities, so that the obtained mineral fibers are of good quality.

The invention provides a composite shape-stabilized phase change material. The phase change material is a crystallized hydrated salt phase change material, and a support material is meerschaum. A preparation method of the phase change material comprises the following steps: performing acid treatment, high-temperature treatment and organic treatment on the meerschaum in sequence; performing an adsorption reaction on the treated meerschaum and a saturated aqueous solution of a crystallized hydrated salt under a vacuum condition to obtain a novel composite shape-stabilized phase change material. The composite shape-stabilized phase change material has the advantages that 1) packaging and shape stabilizing of the phase change material are realized through the porous structure of the meerschaum, the loss of phase change material crystal water is limited successfully through a functional group of the meerschaum, phase separation is reduced, and the crystallization performance and phase change energy storage feature of the crystallized hydrated salt phase change material are ensured; 2) raw materials of the support material and the phase change material are low in prices and readily-available; the composite preparation method is simple and convenient. By adopting the composite shape-stabilized phase change material and the preparation method, the phase separation phenomenon, overcooling phenomenon and leakage are reduced, and the stability of the phase change material in a long-term use process is improved; the phase change material has a wide application prospect in the phase change heat storage field.

The invention discloses an upper cover structure of a lead acid battery. The upper cover structure comprises a cover body and a cover plate, and the cover body is provided with a plurality of filling openings which are corresponding to various chambers leading to a storage battery box body; and the filling openings are respectively provided with a cover cap in a covering manner, a movable cover of the cover plate is arranged on each filling opening, the cover cap is provided with an air vent, and a closed structure which can automatically open a valve according to preset pressure is respectively arranged between the filling openings and the corresponding chambers of the storage battery box body. Compared with the prior art, the upper cover structure of the lead acid battery has beneficialeffects of being capable of limiting loss of sulfuric acid and water in formation and use, thus prolonging service life of the storage battery and avoiding environmental pollution; and the upper cover can be directly arranged on the box body in a capping manner and then formation is carried out, thus simplifying production procedures and then lowering production cost.
