  • Publication number: 20240309421
    Abstract: A method for isolating and selecting Trichoderma Virens with an aerobic denitrification function and a method for remediating a water body with a low carbon-to-nitrogen ratio using the Trichoderma Virens are provided. Compared with the prior art, the biological treatment adopted by the present disclosure can allow the relatively-complete removal of nitrates without producing a residue, and exhibits advantages such as low cost, efficiency, and eco-friendliness. Further, the biological treatment adopted by the present disclosure can enhance the resistance of the fungus to toxic compounds and harsh environments, significantly promote the removal of nitrogen and organic matters in a water body, improve a decontamination ability of a water body, and increase the diversity of microorganisms in a water body, thereby accelerating the promotion of remediation of a water quality of a water body with a low carbon-to-nitrogen ratio. Therefore, the present disclosure has an extensive application potential.

  • Patent number: 11028693
    Abstract: An absorption-induction convectional dust-controlling/removing air/fog curtain device of a fully-mechanized working face and a method thereof, wherein the device includes an extraction type dust-purifying blower, a sector deflector, a shearer external spraying device and an inter-hydraulic-support spraying device. The shearer external spraying devices are mounted at both sides of a shearer body close to rocking arms of a shearer and the inter-hydraulic-support spraying devices are mounted at two un-advanced hydraulic supports and two hydraulic supports at a leeward side of a front drum of the shearer respectively. Two extraction type dust-purifying blowers symmetrically mounted at the rocking arm close to the body of the shearer are started simultaneously with their air inlets exactly facing front and rear drums of the shearer respectively, and air outlets connected with the sector deflector.

  • Publication number: 20210047927
    Abstract: Disclosed are an absorption-induction convectional dust-controlling/removing air/fog curtain device of a fully-mechanized working face and a method thereof, belonging to the technical field of dust removal of coal mine. The device includes an extraction type dust-purifying blower, a sector deflector, a shearer external spraying device and an inter-hydraulic-support spraying device, wherein the shearer external spraying devices are mounted at both sides of a body of a shearer close to rocking arms of the shearer and the inter-hydraulic-support spraying devices are mounted at two un-advanced hydraulic supports and two hydraulic supports at a leeward side of a front drum of the shearer respectively, so that spraying is performed at a certain angle to form corresponding fog curtains so as to perform spraying precipitation for a large amount of dusts produced by support advancing and coal cutting.
