Wherein limiting plates are arranged at the tops of the opposite sides of the two baffles respectively, and the plate conveying device has the advantages that one plate is vertically placed between the two baffles, the U-shaped frame is clamped on the longitudinal support at the bottom of the lifting frame to place the plates, and the plates are separated from one another.

The application relates to a molybdenum-tolerant phosphorus-dissolving bacterium with molybdenum reduction, which is named Serratia ficaria MoTB 2, and is preserved in the China Center for Type Culture Collection (CCTCC) on April 7, 2024, with a preservation number of CCTCC NO.M2024638. The application also relates to application of the molybdenum-tolerant phosphorus-dissolving bacterium with molybdenum reduction in soil or wastewater containing molybdenum ion pollution, and application of the molybdenum-tolerant phosphorus-dissolving bacterium with molybdenum reduction in dissolving insoluble phosphate. The Serratia ficaria MoTB 2 can reduce self-adsorbed Mo (VI) into Mo (V) and Mo (IV) with relatively low toxicity, so as to reduce the toxicity and ecological harm of Mo (VI) in soil or water body, and can activate insoluble phosphate in soil while having high Mo (VI) reduction efficiency.

A composition for selectively removing a first ionic contaminant from a wastewater stream. The composition is formed into a particle. The composition includes a core formed of a non-active material relative to the first ionic contaminant, and, a shell formed from an active material relative to the first ionic contaminant, wherein the active material comprises between 10 to 50 wt % of the particle. The shell may also include a binder material that may be non-active relative to the first ionic contaminant, but active relative to a second ionic contaminant. The core may be formed from a glass-forming material so that a vitrification process may be used for the spent solid waste.

An electrolysis system includes an electrolyzer stack and a contamination mitigation system. The electrolyzer stack includes an injection port fluidly connected with a cathode compartment of the electrolyzer stack. The contamination mitigation system is configured to remove ions from the electrolyzer stack to mitigate ion contamination in the electrolyzer stack. The contamination mitigation system includes a storage tank including formic acid therein and an injection line fluidly coupled between the storage tank and the injection port. The injection line is configured to direct the formic acid from the storage tank to the injection port for injection into the cathode compartment of the electrolyzer stack.

The application discloses a solid capsule with corrosion inhibition and ion adsorption functions and a preparation method thereof, and belongs to the technical field of oil and gas field chemistry. The solid capsule can deliver 1H-benzotriazole (BTA) to a corrosion area of an oil well for targeted corrosion inhibition through a curing reaction of an epoxy resin (EP) and polyethylene imine (PEI), and dense amino groups (-NH2 and -NH-) in a molecular chain of the polyethylene imine (PEI) endow the polyethylene imine (PEI) with strong chelation and electrostatic adsorption capabilities. The solid capsule with corrosion inhibition and ion adsorption functions has a three-dimensional network structure, and through swelling, the structure is fully stretched, the corrosion inhibitor is released, and at the same time, the amino groups in the molecular chain of the PEI are exposed to water, so that the diffusion and combination of heavy metal ions are accelerated. Therefore, a controlled release system with both corrosion inhibition and ion adsorption functions is realized, which provides an innovative solution for solving the problems of corrosion and ion pollution in a complex environment of an oil and gas field.
